| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The consolidated financial statements have been prepared in United States dollars, in accordance with accounting principles generally accepted in the United States ("GAAP"). Effective in fiscal 2012, the Company began to report its first, second and third quarters on a 4-4-5 basis, with the quarter ending on the Friday closest to the last day of each third month. In fiscal 2012, the Company's first quarter ended on March 30, 2012, the second quarter ended on June 29, 2012 and the third quarter ended on September 28, 2012. The Company's fiscal year ended on December 31, 2012. On August 24, 2012, the Company completed the acquisition of Network Equipment Technologies, Inc. (“NET”). The financial results of NET have been included in the Company's consolidated financial statements for the period subsequent to its acquisition. SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The accompanying consolidated financial statements include the accounts of Sonus and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates and Judgments The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and judgments relied upon in preparing these consolidated financial statements include accounting for business combinations, revenue recognition for multiple element arrangements, inventory valuations, assumptions used to determine the fair value of stock-based compensation, intangible assets and goodwill valuations, legal contingencies and recoverability of Sonus' net deferred tax assets and the related valuation allowances. Sonus regularly assesses these estimates and records changes in estimates in the period in which they become known. Sonus bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from those estimates. Business Combinations The Company recognizes identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed and represents the expected future economic benefits arising from other assets acquired in the business combination that are not individually identified and separately recognized. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill to the extent that it identifies adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. Revenue Recognition The Company recognizes revenue from sales when persuasive evidence of an arrangement exists, delivery has occurred, the sale price is fixed or determinable, and collectability of the related receivable is probable. In instances where customer acceptance is required, revenue is deferred until the acceptance has been achieved. When fees for products or services are not fixed and determinable, the Company defers the recording of receivables, deferred revenue and revenue until such time as the fees become due or are collected. Revenue from maintenance and support services is recognized ratably over the service period. Maintenance revenue is deferred until the associated product is accepted by the customer and all other revenue recognition criteria have been met. Maintenance and support services include telephone support, return and repair support and unspecified rights to product upgrades and enhancements. Revenue from other professional services is typically recognized as the services are delivered if all other revenue recognition criteria have been met. The Company's products typically have both software and non-software components that function together to deliver the products' essential functionality. In addition, hardware sold generally cannot be used apart from the software. Therefore, the Company considers its principal products to be both software and hardware-related. Many of the Company's sales involve multiple element arrangements that include product, maintenance and various professional services. Beginning January 1, 2011, the Company adopted the provisions of ASU No. 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”) and ASU No. 2009-14, Software (Topic 985): Certain Revenue Arrangements That Include Software Elements (“ASU 2009-14”) for new and materially modified arrangements that contain tangible products (hardware) with software elements, which comprise the majority of the Company's revenue transactions. For multiple element arrangements entered into subject to the guidance set forth in ASU 2009-13, arrangement consideration is allocated to each element based on the relative selling prices of all of the elements in the arrangement using the fair value hierarchy as required by ASU 2009-13. The Company limits the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations, or subject to customer-specific return or refund privileges. For transactions entered into prior to January 1, 2011 and prospectively for software-only sales, the Company recognizes revenue in accordance with ASC No. 985-605, Software - Revenue Recognition (“ASC 985-605”). Under this guidance, revenue for any undelivered elements that are considered not essential to the functionality of the product and for which vendor-specific objective evidence of selling price (“VSOE”) has been established is deferred and recognized upon delivery utilizing the residual method. If the Company has undelivered product for which VSOE has not been established, it defers all revenue on the entire arrangement until VSOE is established or until such elements are delivered, provided that all other revenue recognition criteria are met. If the Company has undelivered services for which VSOE has not been established, the entire arrangement is recognized as revenue over the longest remaining service period from the point in time that all services have commenced and all products have been delivered, provided that all other revenue recognition criteria are met. The Company establishes VSOE based upon the price charged when the same element is sold separately or established by management having the relevant pricing authority. The Company has VSOE for its maintenance and support services and certain professional services. When VSOE exists it is used to determine the selling price of a deliverable. The Company has not been able to establish VSOE of any of its products and for certain of its services because the Company has not sold such products or services on a stand-alone basis, has not priced its products or services within a narrow range, or has limited sales history. When VSOE is not established, the Company attempts to establish the selling price of each element based on third-party evidence of selling price (“TPE”). The Company's solution typically differs from that of its peers as there are no similar or interchangeable competitor products or services. The Company's various product and service offerings contain a significant level of customization and differentiation and therefore, comparable pricing of competitors' products and services with similar functionality cannot be obtained. Accordingly, the Company is not able to determine TPE for its products or services. When the Company is unable to establish selling price using VSOE or TPE, the Company uses estimated selling price (“ESP”) in its allocation of arrangement consideration for the relevant deliverables. The objective of ESP is to determine the price at which the Company would transact a sale if a product or service was sold on a stand-alone basis. The Company determines ESP for its products and certain services by considering multiple factors including, but not limited to, overall market conditions, including geographic or regional-specific market factors, profit objectives and historical pricing practices for such deliverables. The determination of ESP is a formal process within the Company that includes review and approval by the Company's management. Deferred revenue typically includes customer deposits and amounts associated with partial product shipments and maintenance or service contracts. Deferred revenue expected to be recognized as revenue more than one year subsequent to the balance sheet date is reported with long-term liabilities in the condensed consolidated balance sheets. The Company defers recognition of incremental direct costs, such as cost of goods, third-party installations and commissions, until recognition of the related revenue. Such costs are classified as current assets if the deferred revenue is initially classified as current and noncurrent assets if the related deferred revenue is initially classified as long-term. The Company excludes any taxes assessed by a governmental authority that are directly imposed on a revenue-producing transaction (i.e., sales, use, value added) from its revenue and costs. Reimbursement received for out-of-pocket expenses and shipping costs is recorded as revenue. The Company sells the majority of its products directly to its end customers. For products sold to resellers and distributors with whom the Company has sufficient history regarding the potential for product returns or refunds or any form of concession, the Company recognizes revenue on a sell-in basis. For all other resellers and distributors, the Company recognizes revenue on a sell-through basis. During the preparation of the Company's consolidated financial statements for the three month period ended March 31, 2011 and the accounting analysis for the new maintenance arrangement with a certain customer, the Company determined that the methodology that had been applied in fiscal 2009 and 2010 to the amortization of consideration related to maintenance provided to this customer was not appropriate and resulted in the inappropriate deferral of revenue related to maintenance billings from 2009 to 2010; total revenue recognized over the term of the arrangement was not impacted. This error resulted in the incorrect deferral and therefore, understatement of $3.8 million of service revenue in 2009 ($950,000 in each quarter of fiscal 2009) and related overstatement of 2010 service revenue by $3.8 million ($950,000 in each quarter of fiscal 2010). There is no tax effect on this revenue and therefore the error in service revenue impacted net loss in each year by the same amounts. There is no effect on retained earnings or any other account within the consolidated balance sheet as of December 31, 2010, and no effect on cash provided by operating activities for fiscal 2009 and fiscal 2010. The Company does not believe this error is material to its previously issued historical consolidated financial statements and, therefore, has not adjusted the historical consolidated financial statements. Financial Instruments The carrying amounts of Sonus' financial instruments, which include cash equivalents, marketable securities, investments, accounts receivable, accounts payable and convertible subordinated debt approximate their fair values. All investments in marketable securities are classified as available-for-sale and are reported at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, in Accumulated other comprehensive income (loss), which is a component of stockholders' equity. Unrealized losses that are determined to be other-than-temporary, based on current and expected market conditions, are recognized in earnings. Declines in fair value determined to be credit-related are charged to earnings. The cost of marketable securities sold is determined by the specific identification method. Financial instruments with remaining maturities or that are due within one year from the balance sheet date are classified as current. Financial instruments with remaining maturities or that are payable more than one year from the balance sheet date are classified as noncurrent. Cash and Cash Equivalents Cash equivalents are stated at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, in Accumulated other comprehensive income (loss). Cash equivalents are liquid securities that have remaining maturities of three months or less at the date of purchase. Restricted Cash The Company classifies as restricted cash all cash pledged as collateral to secure long-term obligations and all cash whose use is otherwise limited by contractual provisions. Restricted cash is recorded within other assets on the consolidated balance sheet. Foreign Currency Translation For foreign subsidiaries where the functional currency is the local currency, assets and liabilities are translated into U.S. dollars at the current exchange rate on the balance sheet date. Revenue and expenses are translated at average rates of exchange prevailing during each period. Translation adjustments for these subsidiaries are included in Accumulated other comprehensive income (loss). For foreign subsidiaries where the functional currency is the U.S. dollar, monetary assets and liabilities are translated into U.S. dollars at the current exchange rate on the balance sheet date. Nonmonetary assets and liabilities are remeasured into U.S. dollars at historical exchange rates. Revenue and expense items are translated at average rates of exchange prevailing during each period. Realized and unrealized foreign currency gains and losses arising from transactions denominated in currencies other than the subsidiary's functional currency are reflected in earnings with the exception of intercompany transactions considered to be of a long-term investment nature. The components of foreign currency translation gains (losses), which are reported as a component of General and administrative expenses in the consolidated statements of operations, for the years ended December 31, 2012, 2011 and 2010 are as follows (in thousands):
Inventory Inventory is recorded at the lower of cost or market value using the first-in, first-out convention. The Company reduces the carrying value of inventory for those items that are potentially excess, obsolete or slow-moving based on changes in customer demand, technology developments or other economic factors. Sonus writes down evaluation equipment at the time of shipment to its customers, as it is probable that the inventory value will not be realized. Deferred product costs represent deferred cost of revenue for product shipments to customers prior to satisfaction of Sonus' revenue recognition criteria. Such costs are classified as inventory if the related deferred revenue is initially classified as current. Deferred product costs are recorded in Other assets if the related deferred revenue is initially classified as long-term, and remain a component of noncurrent assets until such costs are recognized in the consolidated statement of operations. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets, which range from two to five years. Leasehold improvements are amortized over the lesser of the lease term or five years. When an asset is sold or retired, the cost and related accumulated depreciation or amortization are eliminated, and the resulting gain or loss, if any, is recognized in income (loss) from operations in the consolidated statement of operations. The Company reviews property and equipment for impairment in the same manner as intangible assets discussed below. Intangible Assets and Goodwill Intangible assets are comprised of intellectual property purchased in 2010 which is amortized over its estimated useful life of five years, and intangible assets arising from the August 24, 2012 acquisition of NET, comprised of developed technology, customer relationships, order backlog and internal use software, which are amortized over their estimated useful lives of four months to approximately six years. Intangible assets are reviewed for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable based upon the estimated undiscounted cash flows. Recoverability of intangible assets with estimated lives and other long-lived assets is measured by a comparison of the carrying amount of an asset or asset group to future net undiscounted cash flows expected to be generated by the asset or asset group. If these comparisons indicate that an asset is not recoverable, the Company will recognize an impairment loss for the amount by which the carrying value of the asset or asset group exceeds the related estimated fair value. Estimated fair value is based on either discounted future operating cash flows or appraised values, depending on the nature of the asset. Goodwill is recorded when the consideration for an acquisition exceeds the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but instead is tested for impairment at least annually or if indicators of potential impairment exist by comparing the fair value of the Company's reporting unit to its carrying value. The Company estimates the fair value of its reporting unit using a discounted cash flow model or other valuation models, such as comparative transactions and market multiples. The Company performs its annual testing on November 30 of each year. Other Assets Other assets are primarily comprised of the long-term portion of deferred cost of goods sold, prepaid expenses and deposits. In the fourth quarter of fiscal 2012, the Company wrote off $7.1 million of prepaid royalties related to products from which the Company does not expect to derive future sales. This amount is included as a component of Cost of revenue - product in the consolidated statement of operations for the year ended December 31, 2012. Stock-Based Compensation The Company's stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options. The fair value of stock option awards is affected by the Company's stock price as well as valuation assumptions, including the volatility of Sonus' stock price, expected term of the option, risk-free interest rate and expected dividends. Research and Development Costs Research and development costs are expensed as incurred. Software Development Costs The costs for the development of new software and substantial enhancements to existing software are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized until the product is available for general release. The Company has determined that technological feasibility is established at the time a working model of the software is completed. The Company's process for developing software is essentially completed concurrently with the establishment of technological feasibility. Accordingly, no costs have been capitalized to date. Concentrations of Credit Risk and Single Source Suppliers The financial instruments that potentially subject Sonus to concentrations of credit risk are cash, cash equivalents, marketable debt securities and accounts receivable. The Company's cash equivalents and marketable debt securities were managed by two financial institutions at both December 31, 2012 and 2011. Certain components and software licenses from third parties used in Sonus' products are procured from single sources of supply. The failure of a supplier, including a subcontractor, to deliver on schedule could delay or interrupt Sonus' delivery of products and thereby materially adversely affect Sonus' revenues and operating results. Sonus has five contract manufacturers. Failure to manage the activities of these manufacturers or any disruption in these relationships could result in the disruption in the supply of its products and in delays in the fulfillment of the Company's customer orders. Advertising Costs Advertising costs are expensed as incurred. Advertising expenses were $1.1 million for the year ended December 31, 2012, $0.2 million for the year ended December 31, 2011 and $0.1 million for the year ended December 31, 2010. Operating Segments The Company operates in a single segment. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and assessing performance. To date, the chief operating decision maker has made such decisions and assessed performance at the company level, as one segment. The Company's chief operating decision maker is its President and Chief Executive Officer. Loss Contingencies and Reserves Loss Contingencies. Sonus is subject to ongoing business risks arising in the ordinary course of business that affect the estimation process of the carrying value of assets, the recording of liabilities and the possibility of various loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be reasonably estimated. Sonus regularly evaluates current information available to determine whether such amounts should be adjusted and records changes in estimates in the period they become known. Allowance for Doubtful Accounts. Sonus establishes billing terms at the time it negotiates purchase agreements with its customers. Sonus monitors its outstanding receivables for timely payments and potential collection issues. An allowance for doubtful accounts is estimated based on Sonus' assessment of the collectability of specific customer accounts. Accrual for Royalties. Sonus accrues for royalties for technology that it licenses from vendors based on established royalty rates and usage. In certain cases, Sonus has been contacted by third parties who claim that Sonus' products infringe on certain intellectual property of the third party. Sonus evaluates these claims and accrues amounts only when it is probable that the obligation has been incurred and the amounts are reasonably estimable. Reserve for Litigation and Legal Fees. Sonus is subject to various legal claims. Sonus reserves for legal contingencies and legal fees when it is probable that a loss has been incurred and the amounts are reasonably estimable. Accounting for Income Taxes Deferred tax assets and liabilities are recognized for the expected future consequences of events that have been reflected in the consolidated financial statements. Deferred tax assets and liabilities are determined based on the differences between the book and tax bases of assets and liabilities and operating loss carryforwards, using tax rates expected to be in effect for the years in which the differences are expected to reverse. Such differences arise primarily from stock-based compensation, depreciation, accruals and reserves, acquired intangible assets, deferred revenue, tax credits, net operating loss carryforwards and allowances for accounts receivable. Sonus records valuation allowances to reduce deferred income tax assets to the amount that is more likely than not to be realized. Sonus has not provided for U.S. income taxes on the undistributed earnings of non-U.S. subsidiaries, as the Company plans to permanently reinvest these amounts. Cumulative undistributed foreign earnings were approximately $19 million at December 31, 2012 and approximately $20 million at December 31, 2011. The Company determines whether it is more likely than not that a tax position will be sustained upon examination. If it is not more likely than not that a position will be sustained, no amount of the benefit attributable to the position is recognized. The tax benefit to be recognized of any tax position that meets the more likely than not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon resolution of the contingency. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for income taxes. Recent Accounting Pronouncements On June 16, 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”), which revises the manner in which entities present comprehensive income in their financial statements. The new guidance requires companies to report components of comprehensive income in either: (1) a continuous statement of comprehensive income; or (2) two separate consecutive statements. ASU 2011-05 does not change the items that must be reported in other comprehensive income. On December 23, 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05 (“ASU 2011-12”), which defers certain provisions of ASU 2011-05, including the provision that requires entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented. The unaffected provisions of ASU 2011-05 became effective for the Company in its reporting of the first quarter of fiscal 2012. The Company has elected to present the Statement of Comprehensive Loss as a separate statement. |

| Business Combinations [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ACQUISITION OF NET | ACQUISITION OF NET On August 24, 2012 (the “NET Acquisition Date”), the Company acquired all of the outstanding common stock of NET for cash consideration of $41.5 million, or $1.35 per share of NET common stock. The acquisition was effected through a merger of a wholly-owned subsidiary of the Company into NET with NET surviving the merger as a wholly-owned subsidiary of the Company. NET is a provider of networking equipment focused on secure real-time communications for Unified Communications ("UC"), SIP trunking, enterprise mobility and IP-based multi-service networking. The Company acquired NET to enhance its position as an enabler of cloud-based UC. The acquisition of NET expands the Company's portfolio of Session Border Controller (“SBC”) solutions for enterprise customers and is expected to bring engineering resources, broader channel capability and a broad U.S. federal government installed base to leverage into SIP-enabled platforms. The transaction has been accounted for as a business combination and the financial results of NET have been included in the Company's condensed consolidated financial statements for the period subsequent to its acquisition. The Company's financial results for year ended December 31, 2012 include $17.3 million of revenue and $9.5 million of net loss attributable to NET for the period subsequent to its acquisition. As of December 31, 2012, the valuation of acquired assets, identifiable intangible assets, uncertain tax liabilities and certain accrued liabilities is preliminary. The Company is in the process of investigating the facts and circumstances existing as of the NET Acquisition Date in order to finalize its valuation. Based on the preliminary purchase price allocation, including adjustments which resulted in a net reduction to goodwill of $0.8 million in the three months ended December 31, 2012, the Company recorded $28.7 million of goodwill, which is primarily due to expected synergies between the combined companies and expanded market opportunities with broader SBC product solution offerings. The acquisition was accounted for as a nontaxable business combination and the Company carried over the existing tax basis of the acquired assets and assumed liabilities. The Company concluded that there was insufficient positive evidence to overcome the more objective evidence of cumulative losses and accordingly, a valuation allowance against these assets has been recorded in purchase accounting. As further described in Note 17, the Company intends to elect under Section 338(g) of the Internal Revenue Code to have the transaction treated as an asset acquisition (i.e., a taxable transaction) and therefore the goodwill will be deductible for tax purposes over 15 years. A summary of the preliminary allocation of the purchase consideration for NET is as follows (in thousands):
The valuation of the acquired intangible assets is inherently subjective and relies on significant unobservable inputs. The Company used an income approach to value the acquired customer relationships and developed technology intangible assets. The valuation for each of these intangible assets was based on estimated projections of expected cash flows to be generated by the assets, discounted to the present value at discount rates commensurate with perceived risk. The valuation assumptions take into consideration the Company's estimates of contract renewal, technology attrition and revenue growth projections. The Company is amortizing the identifiable intangible assets in relation to the expected cash flows from the individual intangible assets over their respective useful lives (see Note 9). The identifiable intangible assets as of the NET Acquisition Date are as follows (in thousands):
Pro Forma Results The following unaudited pro forma information presents the condensed combined results of operations of the Company and NET for the years ended December 31, 2012 and 2011 as if the acquisition of NET had been completed on January 1, 2011 with adjustments to give effect to pro forma events that are directly attributable to the acquisition. These pro forma adjustments include a reduction of historical NET revenue for the fair value adjustment related to acquired deferred revenue, an increase in amortization expense for the acquired identifiable intangible assets, a decrease in historical NET interest expense reflecting the extinguishment of certain of NET's debt as a result of the acquisition and the elimination of transaction costs included in the Company's and NET's historical results, directly attributable to the acquisition from the year ended December 31, 2012 and inclusion of such costs in the year ended December 31, 2011. The unaudited pro forma results do not reflect any operating efficiencies or potential cost savings which may result from the consolidation of the operations of the Company and NET. Accordingly, these unaudited pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the combined company that would have been achieved had the acquisition occurred at the beginning of each period presented, nor are they intended to represent or be indicative of future results of operations (in thousands, except per share amounts):
Acquisition-Related Costs Acquisition-related costs include those costs related to the acquisition that would otherwise not have been incurred by the Company. These costs include professional and services fees, such as legal, audit, consulting, paying agent and other fees and expenses related to cash payments to former NET executives under their NET change of control agreements. The components of acquisition-related costs included in the Company's results of operations for the year ended December 31, 2012 are as follows (in thousands):

| Earnings Per Share [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| EARNINGS (LOSS) PER SHARE | EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding during the period. For periods in which the Company reports net income, diluted net income per share is determined by using the weighted average number of common and dilutive common equivalent shares outstanding during the period unless the effect is antidilutive. The calculations of shares used to compute basic and diluted loss per share are as follows (in thousands):
Options to purchase the Company's common stock and unvested shares of restricted stock aggregating 25.7 million shares for the year ended December 31, 2012, 24.9 million shares for the year ended December 31, 2011 and 20.8 million shares for the year ended December 31, 2010 have not been included in the computation of diluted loss per share because their effect would have been antidilutive. |

| CASH EQUIVALENTS, MARKETABLE SECURITIES AND INVESTMENTS | CASH EQUIVALENTS, MARKETABLE SECURITIES AND INVESTMENTS The Company invests in debt and equity instruments, primarily U.S. government-backed, municipal and corporate obligations, which management believes to be high quality (investment grade) credit instruments. During the years ended December 31, 2012 and December 31, 2011, the Company did not sell any of its available-for-sale securities and accordingly, no such gains or losses were realized. During the year ended December 31, 2010, the Company sold $8.4 million of available-for-sale securities and realized approximately $7,000 of gains and no losses as a result of these sales on a specific identification basis. Marketable securities and investments with continuous unrealized losses for one year or greater at December 31, 2012 were nominal; however, since the Company does not intend to sell these securities and does not believe it will be required to sell any securities before they recover in value, it does not believe these declines are other-than-temporary. On a quarterly basis, the Company reviews its marketable securities and investments to determine if there have been any events that could create a credit impairment. Based on its reviews, the Company does not believe that any impairment existed with its current holdings at December 31, 2012. The amortized cost, gross unrealized gains and losses and fair value of the Company's marketable debt and equity securities and investments at December 31, 2012 and 2011 were comprised of the following (in thousands):
The Company's available-for-sale debt securities that are classified as Investments in the consolidated balance sheet mature after one year but within two years or less from the balance sheet date. Fair Value Hierarchy Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. The three-tier fair value hierarchy is based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows: Level 1. Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2. Level 2 applies to assets or liabilities for which there are inputs that are directly or indirectly observable in the marketplace, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets). Level 3. Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. The following table shows the fair value of the Company's financial assets at December 31, 2012 and 2011. These financial assets are comprised of the Company's available-for-sale debt and equity securities and reported under the captions Cash and cash equivalents, Marketable securities and Investments in the consolidated balance sheets (in thousands):
The Company's marketable securities and investments have been valued on the basis of valuations provided by third-party pricing services, as derived from such services' pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and asked prices, broker/dealer quotations, prices or yields of securities with similar characteristics, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. The Company is ultimately responsible for the consolidated financial statements and underlying estimates. Accordingly, the Company assesses the reasonableness of the valuations provided by the third-party pricing services by reviewing actual trade data, broker/dealer quotes and other similar data, which are obtained from quoted market prices or other sources. |

| RESTRUCTURING ACCRUAL | RESTRUCTURING ACCRUAL On August 7, 2012, the Company announced that it had committed to a restructuring initiative to streamline operations and reduce operating costs by closing and consolidating certain facilities and reducing its worldwide workforce. In connection with this initiative, the Company recorded $7.7 million of restructuring expense in the year ended December 31, 2012, comprised of $3.2 million for severance and related costs to reduce the Company's workforce by approximately 150 people, or 12% of employees worldwide, $4.2 million related to space reductions in three facilities and $0.3 million for the write-off of assets associated with the aforementioned facility consolidations. Of this amount, the Company recorded $5.7 million in the three months ended December 31, 2012 and $2.0 million in the three months ended September 28, 2012. The $4.2 million recorded in the year ended December 31, 2012 related to facilities is comprised of $4.0 million related to space reductions in NET's former corporate headquarters in California, $0.1 million related to space reductions in the former NET facility in New Jersey and $0.1 million to consolidate the Company's offices in France. Restructuring expense is reported separately in the Company's consolidated statements of operations. The Company expects to complete the payments related to severance in the first quarter of fiscal 2013 and the payments related to facilities in fiscal 2016. The portion of restructuring payments due more than one year from the balance sheet date is included in Other long-term liabilities in the Company's consolidated balance sheet. At December 31, 2012, the long-term portion of accrued restructuring was $2.7 million.

| Debt Disclosure [Abstract] | |
| DEBT | DEBT In connection with the Company's acquisition of NET, NET remained obligated under its 3 3/4 % Convertible Senior Notes due December 15, 2014 (the "2007 Notes") and 7 1/4 % Redeemable Convertible Subordinated Debentures due May 15, 2014 (the "1989 Debentures") outstanding at the NET Acquisition Date, subject to the transactions discussed below. The Company has determined that the estimated fair value of its outstanding debt at December 31, 2012 equals its carrying value. Although the debt can be publicly traded, there have been no trading transactions since 2010 and accordingly, the Company has categorized it as a Level 2 within the fair value hierarchy. 3¾% Convertible Senior Notes In December 2007, NET issued $85.0 million of 2007 Notes in a private placement, of which $10.5 million in principal remained outstanding at the NET Acquisition Date, and under which NET remained obligated after the acquisition. The 2007 Notes bear interest at a rate of 3 3/4 % per annum and mature on December 15, 2014. The 2007 Notes are unsecured senior obligations of NET, ranking equal in right of payment to all existing and future senior indebtedness of NET, and senior in right of payment to any existing and future subordinated indebtedness of NET. The 2007 Notes are effectively subordinated to existing and future secured indebtedness of NET to the extent of the assets securing such indebtedness and structurally subordinated to the claims of all existing and future indebtedness and other liabilities of NET's subsidiaries. In connection with the acquisition, the Company neither assumed nor guaranteed NET's obligations under the 2007 Notes. The 2007 Notes are not redeemable by NET prior to the stated maturity date. Prior to the acquisition, a 2007 Note could be converted by a holder, at its option, into shares of NET common stock at a conversion rate of 73.3689 shares of NET common stock per $1,000 principal amount, subject to adjustment in certain events. On August 24, 2012, in connection with the consummation of the acquisition and as provided in the merger agreement, NET entered into a supplemental indenture for the 2007 Notes, which provided, among other things, that, in lieu of being convertible into shares of NET common stock, the 2007 Notes will be convertible into the kind and amount of merger consideration that would have been receivable upon the consummation of the acquisition by a holder of the number of shares of NET common stock issuable upon conversion of such 2007 Notes immediately preceding the effective time of the acquisition. The merger consideration was $1.35 in cash per share of NET common stock. Upon the occurrence of certain fundamental changes including, without limitation, an acquisition of voting control of NET, the liquidation of NET, or NET's common stock ceasing to be traded on a U.S. national securities exchange, a holder of 2007 Notes obtained the right to require NET to purchase for cash all or any part of its 2007 Notes at a purchase price equal to 100% of the principal amount plus any accrued and unpaid interest (including additional interest, if any) up until, but not including, the fundamental change purchase date. The acquisition of NET by the Company constituted a "fundamental change" under the indenture governing the 2007 Notes. Accordingly, as required by the indenture governing the 2007 Notes and as provided in the merger agreement, on August 27, 2012, a fundamental change notice was sent to each holder of 2007 Notes, indicating that each such holder had the right to have all or a portion of its 2007 Notes purchased at a price in cash equal to 100% of the principal amount of the 2007 Notes (or portion thereof), plus any accrued and unpaid interest to, but excluding the fundamental change purchase date of October 12, 2012. In response to the fundamental change notice, $8.1 million in aggregate principal amount of 2007 Notes were tendered for purchase. The remaining $2.4 million in aggregate principal amount is due in 2014. 7¼% Redeemable Convertible Subordinated Debentures In May 1989, NET issued $75.0 million of 1989 Debentures, of which $23.7 million in aggregate principal amount remained outstanding as of the NET Acquisition Date, and under which NET remained obligated after the acquisition. The 1989 Debentures bore interest at a rate of 7 1/4 % per annum and matured according to their terms on May 15, 2014. In connection with the acquisition, the company neither assumed nor guaranteed NET's obligations under the 1989 Debentures. Prior to the acquisition, each 1989 Debenture was convertible at the option of the holder into NET common stock at a conversion price of $31.50 per share and was redeemable at the option of NET. The 1989 Debenture holders were entitled to a sinking fund which began May 15, 2000, of 14 annual payments of 5% of the aggregate principal amount of the 1989 Debentures issued ($3.8 million annually), reduced by any redemption or conversion of the 1989 Debentures. As a result of previous redemptions, the total remaining sinking fund requirement was $1.2 million at the NET Acquisition Date, which, assuming no further redemptions would be due as a final sinking fund payment on May 15, 2014. On August 24, 2012, in connection with the consummation of the acquisition and as provided in the merger agreement, NET entered into a supplemental indenture for the 1989 Debentures, which provided, among other things, that, in lieu of being convertible into shares of NET common stock, the 1989 Debentures would be convertible into the kind and amount of merger consideration that would have been received upon the consummation of the acquisition by a holder of the number of shares of NET common stock issuable upon conversion of such 1989 Debenture immediately preceding the effective time of the acquisition. The merger consideration was $1.35 per share. On August 24, 2012, NET sent a notice to the holders of the 1989 Debentures, notifying them that NET had elected to redeem the entire outstanding aggregate principal amount of the 1989 Debentures. The date for the redemption was September 26, 2012. On the redemption date, the entire outstanding principal amount of the 1989 Debentures became due and payable at a redemption price equal to 100% of the principal amount of the 1989 Debentures plus accrued and unpaid interest to the redemption date. NET paid the aggregate principal amount of $23.7 million plus $0.6 million in accrued interest to the holders of the 1989 Debentures on September 26, 2012 and accordingly, at December 31, 2012, no obligation remained in connection with the Debentures. |

| Stockholders' Equity Note [Abstract] | |
| STOCKHOLDER RIGHTS PLAN | STOCKHOLDER RIGHTS PLAN On June 10, 2011, the Company entered into an amendment to its stockholder rights agreement (the "Rights Plan") to extend the expiration date of the rights in such Rights Plan from June 26, 2011 to June 26, 2013. The amendment was not in response to any acquisition proposal and no other amendments were made to the Rights Plan. The Rights Plan was originally adopted on June 26, 2008 and would have expired on June 26, 2011. Under the Rights Plan, preferred stock purchase rights (the "Rights") were distributed as a dividend at the rate of one Right per share of common stock of the Company held by stockholders of record as of the close of business on July 7, 2008. Each Right entitles the stockholder to purchase from the Company a unit consisting of one one-thousandth of a share (a "Unit") of preferred stock at a purchase price of $25.00 per Unit, subject to adjustment. The Rights generally will be exercisable only if a person or group acquires beneficial ownership of 15% or more of the Company's common stock (which includes for this purpose shares of common stock referenced in derivative transactions or securities), or commences or publicly announces a tender or exchange offer upon consummation of which they would beneficially own 15% or more of the Company's common stock. Subject to certain conditions, a person or group who beneficially owned 15% or more of the outstanding shares of the Company's common stock prior to the adoption of the Rights Plan did not cause the Rights to become exercisable upon adoption of the Rights Plan. Should the Rights become exercisable, the effect would be to dilute the ownership of the beneficial owner(s) who triggered the Rights, as that beneficial owner or group of owners would not receive the Units. |

| STOCK-BASED COMPENSATION PLANS | STOCK-BASED COMPENSATION PLANS 2007 Stock Incentive Plan The Company's 2007 Stock Incentive Plan (the "2007 Plan") was approved at the Company's Annual Meeting of Stockholders held on November 12, 2007, and became effective on that date. The 2007 Plan provides for the award of options to purchase the Company's common stock ("stock options"), stock appreciation rights ("SARs"), restricted common stock ("restricted stock"), performance-based awards, restricted stock units and other stock-based awards to employees, officers, directors (including those directors who are not employees or officers of the Company), consultants and advisors of the Company and its subsidiaries. At the Company's Annual Meeting of Stockholders held on June 16, 2010 (the "2010 Annual Meeting"), the Company's stockholders approved an increase to the number of shares of the Company's common stock available for grant under the 2007 Plan by 20 million shares (the "Amended 2007 Plan"). At December 31, 2012, there were 8.5 million shares available for future issuance under the Amended 2007 Plan. Under the fungible share pool formula, the number of total shares available for future awards under the Amended 2007 Plan would be reduced by the fungible share pool multiple of 1.5 for each share of common stock included in an award other than a stock option or SAR award. Accordingly, the total number of shares awarded in the future under the Amended 2007 Plan could be less than the number of shares currently available for issuance. 2008 Stock Incentive Plan In connection with the acquisition of NET, the Company assumed NET's 2008 Equity Incentive Plan (the "NET 2008 Plan"), which provides for the award of stock options, SARs, restricted stock, performance-based awards and restricted stock units ("RSUs"), and the number of shares available for grant under the 2008 Plan were converted to like Sonus equity awards (the "converted awards") using a conversion factor of 0.75, which was calculated based on the acquisition consideration of $1.35 per share of NET common stock divided by the average of the closing price of Sonus common stock for the ten consecutive days ending with the third trading day that preceded the closing date. This conversion factor was also used to convert the exercise prices of NET stock options to Sonus stock option exercise prices. The converted awards will vest under the same schedules as the respective NET stock options and NET RSUs. The fair values of the NET stock options assumed were estimated using a Black-Scholes option pricing model. The Company recorded $0.9 million as additional purchase consideration for the fair value of the assumed equity awards. The fair value of the assumed awards attributable to future stock-based compensation expense totaled $0.4 million, which is being recorded over a weighted average period of approximately eight months. In December 2012, the Company's Board of Directors approved the re-naming of the NET 2008 Plan to the 2008 Stock Incentive Plan (the "2008 Plan"). At December 31, 2012, there were 2.6 million shares available for future issuance under the 2008 Plan. Under the fungible pool formula, the number of total shares available for future awards under the 2008 Plan would be reduced by the fungible share pool multiple of 1.25 for each share of common stock included in an award other than a stock option or SAR award. Accordingly, the total number of shares awarded in the future under the 2008 Plan could be less than the number of shares currently available for issuance. Chief Executive Officer Agreement On August 7, 2012, the Company and Raymond P. Dolan, the Company's President and Chief Executive Officer (“Mr. Dolan”) executed a letter agreement (the “Amendment”) amending the terms and conditions of Mr. Dolan's employment agreement of October 8, 2010 as amended on February 13, 2011 (the “Agreement”). Under the terms of the Amendment, Mr. Dolan elected to accept shares of restricted stock (the “Salary Shares”) in lieu of base salary for the period from August 10, 2012 through December 31, 2012. Mr. Dolan also elected to receive his fiscal year 2012 target bonus, if earned, in the form of restricted shares (“Bonus Shares”). The Company granted Mr. Dolan 108,398 Salary Shares, which have a total grant date fair value equal to the balance of Mr. Dolan's base salary for the year ending December 31, 2012, calculated by dividing Mr. Dolan's remaining base salary for the year by $1.78, the closing price of the Company's common stock on the date of grant. The Salary Shares vested in full on December 31, 2012. The Company recorded compensation expense related to these awards ratably over the remaining vesting period through December 31, 2012. The Salary Shares are included in the amount reported as “Granted” in the Restricted Stock Awards table below. The Company granted Mr. Dolan 421,348 Bonus Shares, which equals Mr. Dolan's target bonus at the maximum level of achievement (150% of Mr. Dolan's annual base salary), divided by $1.78, the closing price of the Company's common stock on the date of grant. The Company recorded stock-based compensation expense for the Bonus Shares commensurate with the expected achievement level represented by the Company's accrual for its company-wide cash bonus program, as the performance metrics for each are consistent. The Bonus Shares are included in the amount reported as “Granted” in the Performance-Based Stock Awards table below. On February 14, 2013, the Compensation Committee determined that Mr. Dolan had earned 280,899 Bonus Shares, of which 50% of such shares will vest on August 15, 2013 and the remaining 50% of such shares will vest on February 15, 2014. Mr. Dolan forfeited the remaining 140,449 Bonus Shares on February 14, 2013. Stock Option Exchange Offer The Company commenced a voluntary stock option exchange program (the "Exchange Offer") beginning on September 8, 2009 and expiring on October 5, 2009. Shares of restricted stock issued under the Exchange Offer were completely unvested at the time they were granted and vest over a period of three years following the exchange date, with 33 1/3% of the shares vesting annually. The Company recognized the unamortized stock-based compensation expense related to the tendered stock options, aggregating $3.5 million, over the three-year vesting period of the restricted common stock issued under the Exchange Offer. This three-year vesting period ended in October 2012. Stock Options Options are issued to purchase shares of common stock of the Company at prices that are equal to the fair market value of the shares on the date the option is granted. Options generally vest over a period of four years, with 25% of the shares subject to the option vesting on the first anniversary of the grant date and the remaining 75% vesting in equal monthly increments thereafter through the fourth anniversary of the grant date. Options granted under the Amended 2007 Plan generally expire ten years from the date of grant. Options granted under the 2008 Plan generally expire seven years from the date of grant. The grant date fair value of options, adjusted for estimated forfeitures, is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period. Forfeitures are estimated based on historical experience. The activity related to the Company's outstanding stock options during the year ended December 31, 2012 is as follows:
The grant date fair values of options to purchase common stock granted in the years ended December 31, 2012, 2011 and 2010 were estimated using the Black-Scholes valuation model with the following assumptions:
The risk-free interest rate used is the average U.S. Treasury Constant Maturities Rate for the expected life of the award. The expected dividend yield of zero is based on the fact that the Company has never paid dividends and has no present intention to pay cash dividends. The expected life for stock options is based on a combination of the Company's historical option patterns and expectations of future employee actions. The weighted average grant-date fair values of options granted during the year were $1.39 for the year ended December 31, 2012, $1.37 for the year ended December 31, 2011 and $1.65 for the year ended December 31, 2010. The total intrinsic values of options exercised during the year were $0.2 million for the year ended December 31, 2012, $0.9 million for the year ended December 31, 2011 and $1.0 million for the year ended December 31, 2010. The Company received cash from option exercises of $0.3 million in the year ended December 31, 2012, $0.8 million in the year ended December 31, 2011 and $1.0 million in the year ended December 31, 2010. Restricted Stock Grants - Restricted Stock Awards and Restricted Stock Units The Company's outstanding restricted stock grants consist of both restricted stock awards ("RSAs") and RSUs. The Company has no unvested RSUs other than those converted in connection with the NET acquisition. Recipients of RSAs have voting rights and rights to receive dividends, if declared. RSAs generally vest 25% on the first anniversary of the grant date, with the remaining 75% vesting in equal increments semi-annually thereafter. RSAs issued in connection with the Company's Exchange Offer, under which restricted shares were granted on October 6, 2009, vested over a period of three years following the exchange date, with 33 1/3% of the shares vesting annually. The RSUs assumed in connection with the NET acquisition vest over a period of 1.75 years and will be fully vested in August 2013. The grant date fair value of restricted stock grants, adjusted for estimated forfeitures, is recognized as expense on a straight-line basis over the requisite service period. The fair value of restricted stock grants is determined based on the market value of the Company's shares on the date of grant. The activity related to the Company's unvested restricted stock grants for the year ended December 31, 2012 is as follows:
The total fair value of restricted stock grant shares vested was $1.8 million in the year ended December 31, 2012, $3.2 million in the year ended December 31, 2011 and $7.8 million in the year ended December 31, 2010. Performance-Based Stock Awards Similar to recipients of RSAs, recipients of performance-based stock awards have voting rights and rights to dividends, if declared. The Company begins to record stock-based compensation expense for performance-based stock awards at the time that it becomes probable that the respective performance conditions will be achieved. The Company will continue to recognize the grant date fair value of performance-based stock awards through the vest date of the respective awards so long as it remains probable that the related performance conditions will be satisfied. The activity related to the Company's performance-based stock awards for the year ended December 31, 2012 is as follows:
At January 1, 2012, the Company had 1.7 million unvested shares of common stock related to performance-based stock awards. The performance conditions for these awards were not satisfied by December 31, 2011, the end of the performance period. As a result, these shares were forfeited on February 21, 2012, the date that the Company issued a press release reporting its financial results for the quarter and year ended December 31, 2011, and accordingly, no expense was recognized for these awards in 2011. There are 2.0 million shares of the Company's common stock that are not included in the table above. As of December 31, 2012, the Company had established performance conditions for these awards; however, due to the level of discretion that the Compensation Committee of the Board of Directors (the "Compensation Committee") has in determining the final number of shares earned under each performance-based award, the grant date criteria have not been met as of December 31, 2012 and accordingly, these shares are not reported as “granted” in the table above. The Company is recording stock-based compensation expense over the requisite service period for these awards based upon the most probable outcome of the performance conditions as set forth within each agreement. The Company recorded expense of $1.0 million related to performance-based shares in the year ended December 31, 2012. ESPP The Amended and Restated 2000 Employee Stock Purchase Plan (the "ESPP") is designed to provide eligible employees of the Company and its participating subsidiaries an opportunity to purchase common stock of the Company through accumulated payroll deductions. The ESPP provides for six-month consecutive offering periods, with the purchase price of the stock equal to 85% of the market price on the last day of the offering period. Under the ESPP, because employees are entitled to purchase a variable number of shares for a fixed monetary amount, future awards are classified as share-based liabilities and recorded at fair value. However, the maximum number of shares of common stock an employee may purchase during each offering period is 2,500, subject to certain adjustments pursuant to the ESPP. The Company reclassifies these liabilities to Additional paid-in capital at the time of the share purchase, which is the date of the award. On January 1 of each year, the aggregate number of shares of common stock available for purchase under the ESPP increases by the lesser of (i) 2% of the outstanding shares on December 31 of the preceding year or (ii) an amount determined by the Board of Directors of the Company. At December 31, 2012, 25.0 million shares were authorized and 12.4 million shares were available under the ESPP for future issuance. Stock-Based Compensation The consolidated statements of operations include stock-based compensation for the years ended December 31, 2012, 2011 and 2010 as follows (in thousands):
Stock-based compensation expense for the year ended December 31, 2011 includes $0.3 million related to the acceleration of vesting of stock options and restricted stock in connection with the separation of the former Senior Vice President and Chief Financial Officer from the Company. Stock-based compensation expense for the year ended December 31, 2010 includes $5.1 million in the aggregate related to the acceleration of vesting of stock options and restricted stock in connection with the departures of the former President and Chief Executive Officer and the former Executive Vice President and Chief Operating Officer. The Company included stock-based compensation in inventory of approximately $29,000 at December 31, 2012 and $0.1 million at December 31, 2011. There is no income tax benefit for employee stock-based compensation expense for the years ended December 31, 2012, 2011and 2010 due to the valuation allowance recorded. At December 31, 2012, there was $13.1 million, net of expected forfeitures, of unrecognized stock-based compensation expense related to unvested stock options and restricted stock awards. This expense is expected to be recognized over a weighted average period of approximately three years. Common Stock Reserved Common stock reserved for future issuance at December 31, 2012 consists of the following:
The Company's policy is to issue authorized but unissued shares upon the exercise of stock options, grant restricted common stock and performance-based stock awards, and authorize the purchase of shares of the Company's common stock under the ESPP. |

| INCOME TAXES | INCOME TAXES The components of income (loss) from continuing operations before income taxes consist of the following (in thousands):
The provision (benefit) for income taxes from continuing operations consists of the following (in thousands):
A reconciliation of the Company's effective tax rate for continuing operations to the statutory federal rate is as follows:
The following is a summary of the significant components of deferred income tax assets and liabilities (in thousands):
At December 31, 2012, the Company had cumulative net operating losses ("NOL") of $192.4 million for federal income tax purposes and $91.5 million for state income tax purposes. The federal NOL carryforwards expire at various dates from 2020 through 2032. The state NOL expires at various dates from 2013 through 2032. Of the federal NOL, $119.0 million is attributable to stock option deductions. The Company's federal NOL carryforwards for tax return purposes are $24.0 million greater than its recognized federal NOL for financial reporting purposes, primarily due to excess tax benefits (stock compensation deductions in excess of book compensation costs) not recognized for financial statement purposes until realized. The tax benefit of this loss would be recognized for financial statement purposes in the period in which the tax benefit reduces income taxes payable, which will not be recognized until the Company recognizes a reduction in taxes payable from all other NOL carryforwards. In addition, the Company has $7.9 million of deferred tax assets as of December 31, 2012 related to compensation expenses recognized for financial reporting purposes that are not deductible for tax purposes until options are exercised or shares vest. As employees will not exercise the underlying options unless the current market price exceeds the option exercise price and the Company's tax deduction for restricted shares is determined as the shares vest, the ultimate realization of the benefit related to stock options is directly associated with the price of the Company's common stock. At December 31, 2012, the Company's stock price of $1.70 was well below the weighted average exercise price of the Company's stock options of $3.46. With respect to non-U.S. NOL carryovers, the Company's United Kingdom subsidiary has a current year estimated NOL of $0.2 million and a carryover of $2.8 million from its acquisition of NET. The Company also has available federal and state research and development credit carryforwards of $25.5 million that expire at various dates from 2015 through 2032. The Company has available $14.2 million of capital loss carryover resulting from the sale of its Zynetix subsidiary on November 26, 2008. The capital loss is only available to offset capital gains. Because it is not more likely than not that the Company will realize a benefit prior to the expiration of the capital loss carryforward in 2013, a full valuation allowance has been established against the $5.5 million tax benefit associated with this capital loss. During fiscal 2012 and fiscal 2011, the Company performed an analysis to determine if, based on all available evidence, it considered it more likely than not that some portion or all of the recorded deferred tax assets will not be realized in a future period. As a result of the Company's evaluation, the Company concluded that there was insufficient positive evidence to overcome the more objective negative evidence related to its cumulative losses and other factors. Accordingly, the Company has maintained a valuation allowance against its domestic deferred tax assets amounting to $116.9 million at December 31, 2012 and $102.6 million at December 31, 2011. The Company operated under a tax holiday in India, which expired in March 2011. A reconciliation of the Company's unrecognized tax benefits is as follows (in thousands):
The Company recorded liabilities for potential penalties and interest of $14,000 for the year ended December 31, 2012, $14,000 for the year ended December 31, 2011 and $23,000 for the year ended December 31, 2010. The Company does not expect its unrecognized tax benefits to change materially over the next 12 months. Due to the Company's valuation allowance at December 31, 2012, none of the Company's unrecognized tax benefits, if recognized, would affect the effective tax rate. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, as well as various state and foreign jurisdictions. Generally, the tax years 2007 through 2012 remain open to examination by the major taxing jurisdictions to which the Company is subject. The Company's federal NOLs generated prior to 2003 could be adjusted on examination even though the year in which the loss was generated is otherwise closed by the statute of limitations. The Company's primary state jurisdiction, Massachusetts, has open periods from 2008 through 2012. The acquisition of NET was accounted for as a nontaxable business combination and the Company carried over the existing tax basis of the acquired assets and liabilities. Deferred taxes were recorded as part of the business combination based on the differences between the tax basis of the acquired assets or liabilities and their reported amounts for financial reporting purposes. The Company concluded that there was insufficient positive evidence to overcome the more objective negative evidence related to cumulative losses and other factors. Accordingly, the Company recorded a valuation allowance against the majority of the acquired deferred tax assets. With respect to the acquisition of NET, the Company intends to unilaterally elect under Section 338(g) of the Internal Revenue Code to have the acquisition transaction treated as an asset acquisition (i.e., a taxable transaction). The election is not considered part of the business combination and resulted in a step-up in the acquired assets and liabilities to fair market value for tax purposes. During the quarter ended September 28, 2012 as a result of the election, the Company reversed all of the deferred taxes related to NET's assets, liabilities and net operating loss carryovers and the related valuation allowance that were recorded in the business combination. Any resulting taxable gain from the election will be fully offset by NET's operating loss carryovers and no taxes will be payable by the Company as a result of the election. |

| Accounting Policies [Abstract] | |
| Basis of Presentation | BASIS OF PRESENTATION The consolidated financial statements have been prepared in United States dollars, in accordance with accounting principles generally accepted in the United States ("GAAP"). Effective in fiscal 2012, the Company began to report its first, second and third quarters on a 4-4-5 basis, with the quarter ending on the Friday closest to the last day of each third month. In fiscal 2012, the Company's first quarter ended on March 30, 2012, the second quarter ended on June 29, 2012 and the third quarter ended on September 28, 2012. The Company's fiscal year ended on December 31, 2012. On August 24, 2012, the Company completed the acquisition of Network Equipment Technologies, Inc. (“NET”). The financial results of NET have been included in the Company's consolidated financial statements for the period subsequent to its acquisition. |
| Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include the accounts of Sonus and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. |
| Use of Estimates and Judgments | Use of Estimates and Judgments The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and judgments relied upon in preparing these consolidated financial statements include accounting for business combinations, revenue recognition for multiple element arrangements, inventory valuations, assumptions used to determine the fair value of stock-based compensation, intangible assets and goodwill valuations, legal contingencies and recoverability of Sonus' net deferred tax assets and the related valuation allowances. Sonus regularly assesses these estimates and records changes in estimates in the period in which they become known. Sonus bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from those estimates. |
| Business Combinations | Business Combinations The Company recognizes identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed and represents the expected future economic benefits arising from other assets acquired in the business combination that are not individually identified and separately recognized. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill to the extent that it identifies adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. |
| Revenue Recognition | Revenue Recognition The Company recognizes revenue from sales when persuasive evidence of an arrangement exists, delivery has occurred, the sale price is fixed or determinable, and collectability of the related receivable is probable. In instances where customer acceptance is required, revenue is deferred until the acceptance has been achieved. When fees for products or services are not fixed and determinable, the Company defers the recording of receivables, deferred revenue and revenue until such time as the fees become due or are collected. Revenue from maintenance and support services is recognized ratably over the service period. Maintenance revenue is deferred until the associated product is accepted by the customer and all other revenue recognition criteria have been met. Maintenance and support services include telephone support, return and repair support and unspecified rights to product upgrades and enhancements. Revenue from other professional services is typically recognized as the services are delivered if all other revenue recognition criteria have been met. The Company's products typically have both software and non-software components that function together to deliver the products' essential functionality. In addition, hardware sold generally cannot be used apart from the software. Therefore, the Company considers its principal products to be both software and hardware-related. Many of the Company's sales involve multiple element arrangements that include product, maintenance and various professional services. Beginning January 1, 2011, the Company adopted the provisions of ASU No. 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”) and ASU No. 2009-14, Software (Topic 985): Certain Revenue Arrangements That Include Software Elements (“ASU 2009-14”) for new and materially modified arrangements that contain tangible products (hardware) with software elements, which comprise the majority of the Company's revenue transactions. For multiple element arrangements entered into subject to the guidance set forth in ASU 2009-13, arrangement consideration is allocated to each element based on the relative selling prices of all of the elements in the arrangement using the fair value hierarchy as required by ASU 2009-13. The Company limits the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations, or subject to customer-specific return or refund privileges. For transactions entered into prior to January 1, 2011 and prospectively for software-only sales, the Company recognizes revenue in accordance with ASC No. 985-605, Software - Revenue Recognition (“ASC 985-605”). Under this guidance, revenue for any undelivered elements that are considered not essential to the functionality of the product and for which vendor-specific objective evidence of selling price (“VSOE”) has been established is deferred and recognized upon delivery utilizing the residual method. If the Company has undelivered product for which VSOE has not been established, it defers all revenue on the entire arrangement until VSOE is established or until such elements are delivered, provided that all other revenue recognition criteria are met. If the Company has undelivered services for which VSOE has not been established, the entire arrangement is recognized as revenue over the longest remaining service period from the point in time that all services have commenced and all products have been delivered, provided that all other revenue recognition criteria are met. The Company establishes VSOE based upon the price charged when the same element is sold separately or established by management having the relevant pricing authority. The Company has VSOE for its maintenance and support services and certain professional services. When VSOE exists it is used to determine the selling price of a deliverable. The Company has not been able to establish VSOE of any of its products and for certain of its services because the Company has not sold such products or services on a stand-alone basis, has not priced its products or services within a narrow range, or has limited sales history. When VSOE is not established, the Company attempts to establish the selling price of each element based on third-party evidence of selling price (“TPE”). The Company's solution typically differs from that of its peers as there are no similar or interchangeable competitor products or services. The Company's various product and service offerings contain a significant level of customization and differentiation and therefore, comparable pricing of competitors' products and services with similar functionality cannot be obtained. Accordingly, the Company is not able to determine TPE for its products or services. When the Company is unable to establish selling price using VSOE or TPE, the Company uses estimated selling price (“ESP”) in its allocation of arrangement consideration for the relevant deliverables. The objective of ESP is to determine the price at which the Company would transact a sale if a product or service was sold on a stand-alone basis. The Company determines ESP for its products and certain services by considering multiple factors including, but not limited to, overall market conditions, including geographic or regional-specific market factors, profit objectives and historical pricing practices for such deliverables. The determination of ESP is a formal process within the Company that includes review and approval by the Company's management. Deferred revenue typically includes customer deposits and amounts associated with partial product shipments and maintenance or service contracts. Deferred revenue expected to be recognized as revenue more than one year subsequent to the balance sheet date is reported with long-term liabilities in the condensed consolidated balance sheets. The Company defers recognition of incremental direct costs, such as cost of goods, third-party installations and commissions, until recognition of the related revenue. Such costs are classified as current assets if the deferred revenue is initially classified as current and noncurrent assets if the related deferred revenue is initially classified as long-term. The Company excludes any taxes assessed by a governmental authority that are directly imposed on a revenue-producing transaction (i.e., sales, use, value added) from its revenue and costs. Reimbursement received for out-of-pocket expenses and shipping costs is recorded as revenue. The Company sells the majority of its products directly to its end customers. For products sold to resellers and distributors with whom the Company has sufficient history regarding the potential for product returns or refunds or any form of concession, the Company recognizes revenue on a sell-in basis. For all other resellers and distributors, the Company recognizes revenue on a sell-through basis. |
| Financial Instruments | Financial Instruments The carrying amounts of Sonus' financial instruments, which include cash equivalents, marketable securities, investments, accounts receivable, accounts payable and convertible subordinated debt approximate their fair values. All investments in marketable securities are classified as available-for-sale and are reported at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, in Accumulated other comprehensive income (loss), which is a component of stockholders' equity. Unrealized losses that are determined to be other-than-temporary, based on current and expected market conditions, are recognized in earnings. Declines in fair value determined to be credit-related are charged to earnings. The cost of marketable securities sold is determined by the specific identification method. Financial instruments with remaining maturities or that are due within one year from the balance sheet date are classified as current. Financial instruments with remaining maturities or that are payable more than one year from the balance sheet date are classified as noncurrent. |
| Cash and Cash Equivalents | Cash and Cash Equivalents Cash equivalents are stated at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, in Accumulated other comprehensive income (loss). Cash equivalents are liquid securities that have remaining maturities of three months or less at the date of purchase. |
| Restricted Cash | Restricted Cash The Company classifies as restricted cash all cash pledged as collateral to secure long-term obligations and all cash whose use is otherwise limited by contractual provisions. Restricted cash is recorded within other assets on the consolidated balance sheet. |
| Foreign Currency Translation | Foreign Currency Translation For foreign subsidiaries where the functional currency is the local currency, assets and liabilities are translated into U.S. dollars at the current exchange rate on the balance sheet date. Revenue and expenses are translated at average rates of exchange prevailing during each period. Translation adjustments for these subsidiaries are included in Accumulated other comprehensive income (loss). For foreign subsidiaries where the functional currency is the U.S. dollar, monetary assets and liabilities are translated into U.S. dollars at the current exchange rate on the balance sheet date. Nonmonetary assets and liabilities are remeasured into U.S. dollars at historical exchange rates. Revenue and expense items are translated at average rates of exchange prevailing during each period. Realized and unrealized foreign currency gains and losses arising from transactions denominated in currencies other than the subsidiary's functional currency are reflected in earnings with the exception of intercompany transactions considered to be of a long-term investment nature. |
| Inventory | Inventory Inventory is recorded at the lower of cost or market value using the first-in, first-out convention. The Company reduces the carrying value of inventory for those items that are potentially excess, obsolete or slow-moving based on changes in customer demand, technology developments or other economic factors. Sonus writes down evaluation equipment at the time of shipment to its customers, as it is probable that the inventory value will not be realized. Deferred product costs represent deferred cost of revenue for product shipments to customers prior to satisfaction of Sonus' revenue recognition criteria. Such costs are classified as inventory if the related deferred revenue is initially classified as current. Deferred product costs are recorded in Other assets if the related deferred revenue is initially classified as long-term, and remain a component of noncurrent assets until such costs are recognized in the consolidated statement of operations. |
| Property and Equipment | Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets, which range from two to five years. Leasehold improvements are amortized over the lesser of the lease term or five years. When an asset is sold or retired, the cost and related accumulated depreciation or amortization are eliminated, and the resulting gain or loss, if any, is recognized in income (loss) from operations in the consolidated statement of operations. The Company reviews property and equipment for impairment in the same manner as intangible assets discussed below. |
| Intangible Assets and Goodwill | Intangible Assets and Goodwill Intangible assets are comprised of intellectual property purchased in 2010 which is amortized over its estimated useful life of five years, and intangible assets arising from the August 24, 2012 acquisition of NET, comprised of developed technology, customer relationships, order backlog and internal use software, which are amortized over their estimated useful lives of four months to approximately six years. Intangible assets are reviewed for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable based upon the estimated undiscounted cash flows. Recoverability of intangible assets with estimated lives and other long-lived assets is measured by a comparison of the carrying amount of an asset or asset group to future net undiscounted cash flows expected to be generated by the asset or asset group. If these comparisons indicate that an asset is not recoverable, the Company will recognize an impairment loss for the amount by which the carrying value of the asset or asset group exceeds the related estimated fair value. Estimated fair value is based on either discounted future operating cash flows or appraised values, depending on the nature of the asset. Goodwill is recorded when the consideration for an acquisition exceeds the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but instead is tested for impairment at least annually or if indicators of potential impairment exist by comparing the fair value of the Company's reporting unit to its carrying value. The Company estimates the fair value of its reporting unit using a discounted cash flow model or other valuation models, such as comparative transactions and market multiples. The Company performs its annual testing on November 30 of each year. |
| Share-Based Compensation | Stock-Based Compensation The Company's stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options. The fair value of stock option awards is affected by the Company's stock price as well as valuation assumptions, including the volatility of Sonus' stock price, expected term of the option, risk-free interest rate and expected dividends. |
| Research and Development Costs | Research and Development Costs Research and development costs are expensed as incurred. |
| Software Development Costs | Software Development Costs The costs for the development of new software and substantial enhancements to existing software are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized until the product is available for general release. The Company has determined that technological feasibility is established at the time a working model of the software is completed. The Company's process for developing software is essentially completed concurrently with the establishment of technological feasibility. Accordingly, no costs have been capitalized to date. |
| Advertising Costs | Advertising Costs Advertising costs are expensed as incurred. |
| Operating Segments | Operating Segments The Company operates in a single segment. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and assessing performance. To date, the chief operating decision maker has made such decisions and assessed performance at the company level, as one segment. The Company's chief operating decision maker is its President and Chief Executive Officer. |
| Loss Contingencies and Reserves | Loss Contingencies and Reserves Loss Contingencies. Sonus is subject to ongoing business risks arising in the ordinary course of business that affect the estimation process of the carrying value of assets, the recording of liabilities and the possibility of various loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be reasonably estimated. Sonus regularly evaluates current information available to determine whether such amounts should be adjusted and records changes in estimates in the period they become known. Accrual for Royalties. Sonus accrues for royalties for technology that it licenses from vendors based on established royalty rates and usage. In certain cases, Sonus has been contacted by third parties who claim that Sonus' products infringe on certain intellectual property of the third party. Sonus evaluates these claims and accrues amounts only when it is probable that the obligation has been incurred and the amounts are reasonably estimable. Reserve for Litigation and Legal Fees. Sonus is subject to various legal claims. Sonus reserves for legal contingencies and legal fees when it is probable that a loss has been incurred and the amounts are reasonably estimable. |
| Accounting for Income Taxes | Accounting for Income Taxes Deferred tax assets and liabilities are recognized for the expected future consequences of events that have been reflected in the consolidated financial statements. Deferred tax assets and liabilities are determined based on the differences between the book and tax bases of assets and liabilities and operating loss carryforwards, using tax rates expected to be in effect for the years in which the differences are expected to reverse. Such differences arise primarily from stock-based compensation, depreciation, accruals and reserves, acquired intangible assets, deferred revenue, tax credits, net operating loss carryforwards and allowances for accounts receivable. Sonus records valuation allowances to reduce deferred income tax assets to the amount that is more likely than not to be realized. Sonus has not provided for U.S. income taxes on the undistributed earnings of non-U.S. subsidiaries, as the Company plans to permanently reinvest these amounts. Cumulative undistributed foreign earnings were approximately $19 million at December 31, 2012 and approximately $20 million at December 31, 2011. The Company determines whether it is more likely than not that a tax position will be sustained upon examination. If it is not more likely than not that a position will be sustained, no amount of the benefit attributable to the position is recognized. The tax benefit to be recognized of any tax position that meets the more likely than not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon resolution of the contingency. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for income taxes. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements On June 16, 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”), which revises the manner in which entities present comprehensive income in their financial statements. The new guidance requires companies to report components of comprehensive income in either: (1) a continuous statement of comprehensive income; or (2) two separate consecutive statements. ASU 2011-05 does not change the items that must be reported in other comprehensive income. On December 23, 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05 (“ASU 2011-12”), which defers certain provisions of ASU 2011-05, including the provision that requires entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented. The unaffected provisions of ASU 2011-05 became effective for the Company in its reporting of the first quarter of fiscal 2012. The Company has elected to present the Statement of Comprehensive Loss as a separate statement. |
