| Accounting Policies [Abstract] | |
| BASIS OF PRESENTATION | BASIS OF PRESENTATION Business Sonus Networks, Inc. (“Sonus” or the “Company”) is a leading provider of networked solutions for communications service providers (e.g., telecommunications, wireless and cable service providers) and enterprises to help them advance, protect and unify their communications and improve collaboration. Sonus helps many of the world's leading communications service providers and enterprises embrace the next generation of Session Initiation Protocol ("SIP") and 4G/LTE (Long Term Evolution)-based solutions, including Voice over IP ("VoIP") video and Unified Communications ("UC") through secure, reliable and scalable Internet Protocol ("IP") networks. Sonus' products include session border controllers ("SBCs"), diameter signaling controllers ("DSCs"), policy/routing servers, network intelligence applications (VellOS, which is designed to provide Network-as-a-Service ("NaaS")), media and signaling gateways and network analytics tools. The Company utilizes both direct and indirect sales channels to reach its target customers. Customers and prospective customers in the service provider space are traditional and emerging communications service providers, including long distance carriers, local exchange carriers, Internet service providers, wireless operators, cable operators, international telephone companies and carriers that provide services to other carriers. Enterprise customers and target enterprise customers include financial institutions, retailers, state and local governments, and other multinational corporations. Basis of Presentation In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring items, necessary for their fair presentation with accounting principles generally accepted in the United States of America ("GAAP") and with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Interim results are not necessarily indicative of results for a full year or any future interim period. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2014 (the "Annual Report") filed with the SEC on February 25, 2015. During the preparation of the Company's consolidated financial statements for the three month period ended June 26, 2015, the Company identified an error related to the historical foreign translation of depreciation expense on certain foreign fixed assets that resulted in a historical understatement of expense in prior fiscal years totaling $1.4 million on a cumulative basis. There is no tax effect on these expenses as the amounts were calculated in the appropriate foreign currencies. The Company does not believe this error is material to its previously issued historical consolidated financial statements for any of the periods impacted and accordingly, has not adjusted its historical financial statements. The Company recorded the cumulative impact of the adjustment in the three months ended June 26, 2015. This adjustment resulted in a one-time $1.4 million overstatement of depreciation expense, which is included in the Company's condensed consolidated statement of operations for the nine months ended September 25, 2015. The Company does not believe this adjustment is material to its condensed consolidated financial statements for the periods presented. The Company effected a one-for-five reverse stock split of its issued, outstanding and authorized common stock, which became effective as of the commencement of trading on the NASDAQ Global Select Market on January 30, 2015. Unless otherwise indicated, all references herein to shares outstanding and share issuances have been adjusted to give effect to the Company's January 2015 reverse stock split. On January 2, 2015 (the "Treq Asset Acquisition Date"), the Company acquired from Treq Labs, Inc. ("Treq") certain assets related to Treq's business of designing, developing, marketing, selling, servicing and maintaining software-defined networking ("SDN") technology, SDN controller software and SDN management software (the "SDN Business"). The financial results of the SDN Business are included in the Company's condensed consolidated financial statements starting on the Treq Asset Acquisition Date. On February 19, 2014 (the "PT Acquisition Date"), the Company completed the acquisition of Performance Technologies, Incorporated ("PT"). The financial results of PT are included in the Company's condensed consolidated financial statements starting on the PT Acquisition Date. Significant Accounting Policies The Company's significant accounting policies are disclosed in Note 2 to the Consolidated Financial Statements included in the Annual Report. There were no material changes to the significant accounting policies during the three or nine months ended September 25, 2015. Principles of Consolidation The condensed consolidated financial statements include the accounts of Sonus and its wholly-owned subsidiaries. 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, including impairments, 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. Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include cash equivalents, marketable securities, investments, accounts receivable, accounts payable and other long-term liabilities, approximate their fair values. 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. Recent Accounting Pronouncements In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-16, Simplifying the Accounting for Measurement-Period Adjustments ("ASU 2015-16"), which eliminates the requirement to restate prior periods to reflect adjustments made to provisional amounts recognized in a business combination. Under ASU 2015-16, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, rather than retrospectively, as had previously been required. ASU 2015-16 also requires acquirers to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for the Company beginning January 1, 2016. The adoption of ASU 2015-16 is not expected to have a material impact on the Company's consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory ("ASU 2015-11"). ASU 2015-11 simplifies the measurement of inventory by requiring entities to measure most inventory at the lower of cost and net realizable value, replacing the previous requirement to measure most inventory at the lower of cost or market. ASU 2015-11 does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. ASU 2015-11 is effective for the Company for both interim and annual reporting periods beginning January 1, 2017. The adoption of ASU 2015-11 is not expected to have a material impact on the Company's consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). ASU 2014-15 provides guidelines for determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity's ability to continue as a going concern. ASU 2014-15 is effective for the Company for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The adoption of ASU 2014-15 is not expected to have a material impact on the Company's consolidated financial statements. In June 2014, the FASB issued ASU 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force) (“ASU 2014-12”). ASU 2014-12 clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent upon the entity’s satisfaction of a performance target until it becomes probable that the performance target will be met. ASU 2014-12 does not contain any new disclosure requirements. ASU 2014-12 is effective for the Company beginning January 1, 2016. The adoption of ASU 2014-12 is not expected to have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) its final standard on revenue from contracts with customers. ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the revenue model to contracts within its scope, an entity identifies the contract(s) with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to the performance obligations in the contract and recognizes revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 applies to all contracts with customers that are within the scope of other topics in the FASB ASC. Certain of ASU 2014-09’s provisions also apply to transfers of nonfinancial assets, including in-substance nonfinancial assets that are not an output of an entity’s ordinary activities (i.e., property, plant and equipment; real estate; or intangible assets). Existing accounting guidance applicable to these transfers has been amended or superseded. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the original effective date of interim and annual reporting periods by one year. As a result, public entities would not be required to apply the new revenue standard until annual reporting periods beginning after December 15, 2017. The Company is currently assessing the potential impact of the adoption of ASU 2014-09 on its consolidated financial statements. |

| BUSINESS ACQUISITIONS | BUSINESS ACQUISITIONS Treq Labs, Inc. On the Treq Asset Acquisition Date, the Company acquired from Treq its SDN Business. The SDN Business provides solutions that optimize networks for voice, video and UC for both enterprise and service provider customers. The Company believes that the acquisition of the SDN Business will accelerate Sonus' delivery of its SDN strategy. In consideration for the acquisition of the SDN Business, Sonus paid $10.1 million in cash on the Treq Asset Acquisition Date, with an additional consideration payment of $750,000 paid on July 2, 2015 and a second additional consideration payment of $750,000 due on January 4, 2016. The Company also entered into an Earn-Out Agreement, dated as of January 2, 2015, with Treq and Karl F. May, the seller representative in the transaction (the "Earn-Out Agreement"), under which the Company has agreed to issue up to an aggregate of 1.3 million shares of common stock over a three-year period subsequent to the Treq Asset Acquisition Date if aggregate revenue thresholds of at least $60 million are achieved by the SDN Business during that period, and up to an aggregate of an additional 2.2 million shares (3.5 million shares in total) if aggregate revenue thresholds of at least $150 million are achieved by the SDN Business during that period. If the initial revenue thresholds are not met, no shares will be issued. Based on historical and forecasted sales, no incremental contingent consideration was recorded either initially as of the Treq Asset Acquisition Date or through September 25, 2015. Any shares issued pursuant to the Earn-Out Agreement will be issued in reliance on the exemption from registration available under Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), and will be subsequently registered for resale under the Securities Act by the Company. The transaction has been accounted for as a business combination. The Company finalized its valuation of the identifiable intangible assets in the second quarter of fiscal 2015. Based on the purchase price allocation, the Company recorded $1.0 million of goodwill, primarily due to expected synergies between the combined companies and expanded market opportunities. The goodwill is deductible for tax purposes. A summary of the purchase consideration for the SDN Business 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 preliminarily value the acquired in-process research and development 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 technology attrition and revenue growth projections. During the three months ended September 25, 2015, the Company began to record amortization expense in connection with certain of the in-process research and development intangible assets related to a product that became generally available in the quarter and accordingly, reclassified the asset with a cost basis of $7.5 million to its developed technology intangible assets. The Company will begin to amortize the remaining in-process research and development intangible asset at the time that the related product becomes generally available. Once the products become generally available, the Company will amortize the identifiable intangible assets in relation to the expected cash flows from the individual intangible assets over their respective useful lives (see Note 6). The actual results of the SDN Business for the period since the Treq Asset Acquisition Date were not material to the Company's financial results and accordingly, the Company has not provided pro forma information. Performance Technologies, Incorporated On the PT Acquisition Date, the Company acquired all of the outstanding common stock of PT for cash consideration of $35.0 million, or $3.75 per share of PT common stock. This acquisition has enabled Sonus to expand and diversify its overall portfolio to include both legacy signaling and an integrated, virtualized Diameter and SIP-based signaling technology and acquire expertise to enable mobile service providers to offer new real-time multimedia services through their mobile, cloud-based infrastructure. Delivering these services across the LTE next-generation mobile networks requires adoption of the next-generation signaling technology known in the industry as Diameter Signal. The transaction has been accounted for as a business combination. The Company finalized the valuation of acquired assets, identifiable intangible assets and certain accrued liabilities in the fourth quarter of 2014. The Company recorded $8.8 million of goodwill, primarily due to expected synergies between the combined companies and expanded market opportunities. The goodwill is not deductible for tax purposes. A summary of the allocation of the purchase consideration for PT 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 preliminarily 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 6). The Company has not provided pro forma information as the results of PT are not material to the Company's financial results. Acquisition-Related Expenses Acquisition-related expenses include those expenses related to acquisitions that would otherwise not have been incurred by the Company. These expenses include professional and services fees, such as legal, audit, consulting, paying agent and other fees, as well as cash payments to certain employees of acquired companies in connection with change of control agreements. The amount recorded in the nine months ended September 25, 2015 relates to professional fees in connection with the acquisition of the SDN Business. The amount recorded in the nine months ended September 26, 2014 represents professional and services fees and expenses related to cash payments to certain former PT executives under their respective change of control agreements in connection with the PT acquisition. The components of acquisition-related costs included in the Company's results of operations for the nine months ended September 25, 2015 and September 26, 2014 are as follows (in thousands):
Sale of Multi-Protocol Server Business On June 20, 2014 (the "MPS Sale Date"), the Company sold its PT Multi-Protocol Server ("MPS") business for $2.0 million to an affiliate of Sunhillo Corporation, comprised of $0.2 million of inventory, $0.1 million of fixed assets, $0.2 million of deferred revenue and $1.9 million of PT goodwill allocable to the MPS business. The Company had acquired the MPS business in connection with the acquisition of PT. The results of operations of the MPS business are excluded from the Company's condensed consolidated results after the MPS Sale Date. |

| 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, unvested shares of restricted stock, unvested shares of performance-based stock and shares in connection with future purchases under the Company's Amended and Restated 2000 Employee Stock Purchase Plan, as amended (the "ESPP"), aggregating 8.6 million shares for the three and nine months ended September 25, 2015 and 8.4 million shares for the three and nine months ended September 26, 2014 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 AND INVESTMENTS The Company invests in debt instruments, primarily U.S. government-backed, municipal and corporate obligations, which management believes to be high quality (investment grade) credit instruments. During the three months ended March 28, 2014, the Company sold $45.9 million of its available-for-sale securities and realized gross gains aggregating $46,000, which are included as a component of Other income (expense), net in the Company's condensed consolidated statement of operations for the nine months ended September 26, 2014. The Company did not realize any gross losses on these sales. In addition, $41.7 million of the Company's available-for-sale securities matured during the three months ended March 28, 2014 and were redeemed upon maturity. The Company did not sell any of its available-for-sale securities during the three or nine months ended September 25, 2015 or the three months ended September 26, 2014. Investments with continuous unrealized losses for one year or greater at September 25, 2015 were nominal. Since the Company currently 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 September 25, 2015. The amortized cost, gross unrealized gains and losses and fair value of the Company's marketable debt securities and investments at September 25, 2015 and December 31, 2014 were comprised of the following (in thousands):
The Company's available-for-sale debt securities classified as Investments in the condensed consolidated balance sheets at September 25, 2015 and December 31, 2014 had maturity dates 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 September 25, 2015 and December 31, 2014. These financial assets are comprised of the Company's available-for-sale debt securities and reported under the captions Cash and cash equivalents, Marketable securities and Investments in the condensed consolidated balance sheets (in thousands):
The Company's investments have been valued with the assistance 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 condensed 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. |

The Company will begin to amortize the remaining in-process research and development intangible asset at the time that the related product becomes generally available. The Company will amortize the identifiable intangible assets in relation to the expected cash flows from the individual intangible assets over their respective useful lives, which the Company expects will occur over the next several quarters.

| RESTRUCTURING ACCRUAL | RESTRUCTURING ACCRUAL 2015 Restructuring Initiative To better align the Company's cost structure to its current revenue expectations, in April 2015, the Company announced a cost reduction review. As part of this review, on April 16, 2015, the Company initiated a restructuring plan to reduce its workforce by approximately 150 positions, or 12.5% of its worldwide workforce (the "2015 Restructuring Initiative"). In connection with the 2015 Restructuring Initiative, the Company recorded $2.9 million of restructuring expense for severance and related costs in the three months ended June 26, 2015. The Company recorded an adjustment of $0.1 million in the three months ended September 25, 2015 for changes in severance amounts paid to certain individuals. A summary of the 2015 Restructuring Initiative accrual activity for the nine months ended September 25, 2015 is as follows (in thousands):
The Company expects that the remaining amounts accrued under the 2015 Restructuring Initiative will be paid in the fourth quarter of 2015. 2012 Restructuring Initiative In August 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 (the "2012 Restructuring Initiative"). The Company regularly reviews its restructuring accruals against expected cash expenditures to determine if adjustments are required. As a result of such reviews, the Company recorded credits to restructuring expense aggregating $1.7 million in the nine months ended September 25, 2015. This amount is comprised of a credit of $1.4 million recorded in the three months ended June 26, 2015 in connection with a settlement with the landlord of the Company's Fremont, California facility to vacate the facility without penalty or future payments and a credit of $0.3 million recorded in the three months ended March 27, 2015. The amount reversed in the three months ended March 27, 2015 is comprised of approximately $272,000 for facilities in connection with a settlement with the landlord of the Company's Dulles, Virginia facility for an amount that was lower than had previously been accrued and approximately $67,000 in connection with changes in the amounts of severance ultimately paid to certain individuals. The Company also recorded $0.1 million of restructuring expense in the three months ended September 25, 2015 related to vacating the Company's Rochester, New York facility. The Company recorded $0.7 million of restructuring expense in the three months ended September 26, 2014 and $2.2 million in the nine months ended September 26, 2014 for severance and related costs in connection with reducing its workforce. A summary of the 2012 Restructuring Initiative accrual activity for the nine months ended September 25, 2015 is as follows (in thousands):
The Company expects that the remaining amounts for severance accrued under the 2012 Restructuring Initiative will be paid in the fourth quarter of 2015. Balance Sheet Classification of Restructuring Accruals The current portion of the restructuring accrual is included as a component of Accrued expenses in the Company's condensed consolidated balance sheets. 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 condensed consolidated balance sheets. At September 25, 2015, all of the restructuring accrual was included in Accrued expenses, as there was no long-term portion. The long-term portion of accrued restructuring was $1.9 million at December 31, 2014. |

| Equity [Abstract] | |
| COMMON STOCK REPURCHASES AND UNDERWRITTEN OFFERING | COMMON STOCK REPURCHASES AND UNDERWRITTEN OFFERING Stock Buyback Program On July 29, 2013, the Company announced that its Board of Directors had authorized a stock buyback program to repurchase up to $100 million of the Company's common stock from time to time on the open market or in privately negotiated transactions. The timing and amount of any shares repurchased will be determined by the Company's management based on its evaluation of market conditions and other factors. The Company may elect to implement a 10b5-1 repurchase program, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The Company has not implemented such a 10b5-1 repurchase program to date. The stock buyback program may be suspended or discontinued at any time. The stock buyback program is being funded using the Company's working capital. During the nine months ended September 25, 2015, the Company spent $6.1 million, including transaction fees, to repurchase and retire 0.4 million shares of its common stock under the stock buyback program. During the nine months ended September 26, 2014, the Company spent $14.7 million, including transaction fees, to repurchase and retire 0.8 million shares of its common stock under the stock buyback program. At September 25, 2015, the Company had $16.8 million remaining under the stock buyback program for future repurchases. Underwritten Offering On March 20, 2014, the Company announced the commencement of an underwritten public offering of 7.5 million shares of its common stock on behalf of Galahad Securities Limited and its affiliated entities (collectively, the "Legatum Group"). The underwriter of the offering was granted a 30-day option to purchase up to 1.125 million additional shares from the Legatum Group. The Legatum Group received all the proceeds from the underwritten offering; no shares in the underwritten offering were sold by the Company or any of its officers or directors. The Company purchased 4.3 million shares of its common stock from the underwriter for $17.4410 per share, the price equal to the price paid by the underwriter to the Legatum Group in the underwritten offering, for a total of $75.3 million, including transaction fees of $0.3 million. This repurchase was not completed under the Company's stock buyback program. The Company funded the share repurchase with cash on hand. The repurchased shares were retired upon completion of the transaction. |

| STOCK-BASED COMPENSATION PLANS | STOCK-BASED COMPENSATION PLANS Stock Incentive Plan The Company's 2007 Stock Incentive Plan, as amended (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 awards ("RSAs"), restricted common stock units ("RSUs"), performance-based stock awards ("PSAs"), performance-based stock units ("PSUs") 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 its June 11, 2015 annual meeting of stockholders, the Company's stockholders approved amendments to the 2007 Plan to, among other things:
Executive and Board of Directors Equity Arrangements In connection with the Company's annual incentive program, 22 executives of the Company were given the choice to receive all or half of their fiscal year 2015 bonuses (the "2015 Bonus"), if any were earned, in the form of shares of the Company's common stock (the "2015 Bonus Shares"). Each executive could also elect not to participate in this program and to earn his or her 2015 Bonus, if any, in the form of cash. Under this program, the amount of the 2015 Bonus, if any, for each executive would be determined by the Compensation Committee of the Board of Directors of the Company (the "Compensation Committee"). The number of shares of the Company's common stock that would be granted to those executives who elected to receive their 2015 Bonus entirely in the form of shares of common stock would be calculated by dividing an amount equal to 1.5 times each executive's 2015 Bonus earned by $20.55, the closing price of the Company's common stock on January 2, 2015. The number of shares of the Company's common stock that would be granted to those executives who elected to receive one-half of their 2015 Bonus in the form of shares of common stock would be calculated by dividing an amount equal to 1.5 times one-half of each executive's 2015 Bonus earned by $20.55, with the cash portion equal 50% of their respective 2015 Bonus earned. Under this program, the 2015 Bonus, if any, would be granted and/or paid on a date concurrent with the timing of the payout of bonuses under the Company-wide incentive bonus program and would be fully vested on the date of grant. Of the eligible executives, 16 elected to receive their entire 2015 Bonus in shares of common stock, five elected to receive 50% of their 2015 Bonus in shares of common stock and 50% in cash and one elected not to participate and instead to receive his entire 2015 Bonus in cash. As of September 25, 2015, four participants in the 2015 Bonus program had separated from the Company and accordingly, forfeited any 2015 Bonus Shares they might otherwise have earned, subject to the terms of their respective employment agreements. The Company determined that the grant date criteria for the 2015 Bonus Shares was met on July 2, 2015, and accordingly, recorded stock-based compensation expense based on the grant date fair value of $6.79 per share. Subsequent to that date, in September 2015, the Compensation Committee considered the impact on employee retention and incentive compensation caused by the drop in the price of the Company's common stock since January 2, 2015, and indicated its intent to pay all such executives their 2015 Bonus, if any is earned, in cash. As a result, as of September 25, 2015, the Company reclassified the stock-based compensation expense recorded through that date in connection with the 2015 Bonus Shares aggregating $1.0 million from Additional paid-in capital to Accrued expenses. In addition, the Company recorded incremental bonus expense of $1.3 million related to the estimated 2015 Bonus payment, which the Company expects to pay in March 2016. The Company will not record any additional stock-based compensation expense in subsequent periods in connection with the 2015 Bonus Shares, but will instead record bonus expense through December 31, 2015. On January 22, 2014, 21 executives of the Company were given the choice to receive all or half of their fiscal year 2014 bonuses (the "2014 Bonus"), if any were earned, in the form of shares of the Company's common stock (the "2014 Bonus Shares"). Of the eligible executives, 17 elected to receive their entire 2014 Bonus in shares of common stock, while four elected to receive 50% of their 2014 Bonus in shares of common stock and 50% in cash. The 2014 Bonus Shares were granted on February 20, 2015 and vested immediately. The Company granted approximately 266,000 2014 Bonus Shares, with the number of shares granted calculated by dividing amounts equal to 1.5 times each executive's 2014 Bonus earned, as determined by the Compensation Committee, by $15.40, the closing price of the Company's common stock on January 2, 2014. The Company recorded stock-based compensation expense for the 2014 Bonus Shares from January 1, 2014 through the grant date. These shares are reported as both "Granted" and "Vested" in the RSA table below. On March 16, 2015, the Company granted an aggregate of 131,250 PSUs with both market and service conditions to eight of its executives. The terms of the PSUs are such that up to one-third of the shares subject to the PSUs will vest on each of the first, second and third anniversaries of the date of grant (collectively, the "Vesting Dates") to the extent of achievement of the Company's total shareholder return ("TSR") compared to the TSR of the companies included in the NASDAQ Telecommunications Index for the same Performance Period, measured by the Compensation Committee at the end of each of the 2015, 2016 and 2017 fiscal years, respectively (each, a "Performance Period"). The shares determined to be earned will vest on the anniversary of the grant date following each Performance Period. Shares subject to the PSUs that fail to be earned will be forfeited. The PSUs include a market condition that requires the use of a Monte Carlo simulation approach to model future stock price movements based upon the risk-free rate of return, the volatility of each entity, and the pair-wise covariance between each entity. These results were then used to calculate the grant date fair values of the PSUs. The Company is recording expense for the PSUs through the final Vesting Date of March 16, 2018. The PSUs are reported as "Granted" in the performance-based awards table below. In connection with the separation of two executives from the Company during the second quarter of 2015 and in accordance with their respective employment agreements with the Company, the Company accelerated the vesting of certain unvested stock options, RSAs and PSUs. These RSAs and PSUs are reported as "Vested" in the respective tables below. Stock Options The activity related to the Company's outstanding stock options during the nine months ended September 25, 2015 is as follows:
The grant date fair values of options to purchase common stock granted in the three and nine months ended September 25, 2015 were estimated using the Black-Scholes valuation model with the following assumptions:
Additional information regarding the Company's stock options for the three and nine months ended September 25, 2015 is as follows:
Restricted Stock Awards and Units The activity related to the Company's RSAs for the nine months ended September 25, 2015 is as follows:
The activity related to the Company's unvested RSUs for the nine months ended September 25, 2015 is as follows:
The total fair value of shares of restricted stock that vested during the nine months ended September 25, 2015 was $8.3 million. Performance-Based Stock Awards and Units The activity related to the Company's PSAs for the nine months ended September 25, 2015 is as follows:
The activity related to the Company's PSUs for the nine months ended September 25, 2015 is as follows:
Employee Stock Purchase Plan The Company's ESPP provides for six-month offering periods with the purchase price of the stock equal to 85% of the lesser of the market price on the first or last day of the offering period. The maximum number of shares of common stock an employee may purchase during each offering period is 500, subject to certain adjustments pursuant to the ESPP. Stock-Based Compensation The condensed consolidated statements of operations include stock-based compensation for the three and nine months ended September 25, 2015 and September 26, 2014 as follows (in thousands):
There is no income tax benefit for employee stock-based compensation expense for the nine months ended September 25, 2015 or September 26, 2014 due to the valuation allowance recorded. At September 25, 2015, there was $34.1 million, net of expected forfeitures, of unrecognized stock-based compensation expense related to unvested stock options, awards and units. This expense is expected to be recognized over a weighted average period of approximately two years. |

| Commitments and Contingencies Disclosure [Abstract] | |
| COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES As previously reported in the Company's Quarterly Reports on Form 10-Q, Part II, Item 1., for the fiscal quarters ended March 27, 2015 and June 26, 2015, Ming Huang, a purported shareholder of the Company, filed a Class Action Complaint (Civil Action No. 3:15-02407) on April 6, 2015, alleging violations of the federal securities laws (the “Complaint”) in the United States District Court for the District of New Jersey (the "Court"), against the Company and two of its officers, Raymond P. Dolan, the Company’s President and Chief Executive Officer, and Mark T. Greenquist, the Company’s Chief Financial Officer (collectively, the “Defendants”). On September 21, 2015, in response to motions subsequently filed with the Court by four other purported shareholders of the Company seeking status as lead plaintiff, the Court appointed Richard Sousa as lead plaintiff (the "Plaintiff") in this case. The Plaintiff claims to represent purchasers of the Company’s common stock during the period from October 23, 2014 to March 24, 2015, and seeks unspecified damages. The principal allegation contained in the Complaint is that the Defendants made misleading forward-looking statements concerning the Company’s fiscal first quarter of 2015 financial performance. On September 22, 2015, the Company filed a Motion to Transfer this case to the United States District Court for the District of Massachusetts (the "Motion to Transfer"). The Plaintiff filed his opposition to the Motion to Transfer on October 5, 2015, and the Company filed its reply to the Motion to Transfer on October 13, 2015. The Company believes that the Defendants have meritorious defenses to the allegations made in the Complaint and does not expect the results of this suit to have a material effect on its business or consolidated financial statements. In addition, the Company is often a party to disputes and legal proceedings that it considers routine and incidental to its business. Management does not expect the results of any of these actions to have a material effect on the Company's business or consolidated financial statements. |

| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring items, necessary for their fair presentation with accounting principles generally accepted in the United States of America ("GAAP") and with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Interim results are not necessarily indicative of results for a full year or any future interim period. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2014 (the "Annual Report") filed with the SEC on February 25, 2015. During the preparation of the Company's consolidated financial statements for the three month period ended June 26, 2015, the Company identified an error related to the historical foreign translation of depreciation expense on certain foreign fixed assets that resulted in a historical understatement of expense in prior fiscal years totaling $1.4 million on a cumulative basis. There is no tax effect on these expenses as the amounts were calculated in the appropriate foreign currencies. The Company does not believe this error is material to its previously issued historical consolidated financial statements for any of the periods impacted and accordingly, has not adjusted its historical financial statements. The Company recorded the cumulative impact of the adjustment in the three months ended June 26, 2015. This adjustment resulted in a one-time $1.4 million overstatement of depreciation expense, which is included in the Company's condensed consolidated statement of operations for the nine months ended September 25, 2015. The Company does not believe this adjustment is material to its condensed consolidated financial statements for the periods presented. The Company effected a one-for-five reverse stock split of its issued, outstanding and authorized common stock, which became effective as of the commencement of trading on the NASDAQ Global Select Market on January 30, 2015. Unless otherwise indicated, all references herein to shares outstanding and share issuances have been adjusted to give effect to the Company's January 2015 reverse stock split. On January 2, 2015 (the "Treq Asset Acquisition Date"), the Company acquired from Treq Labs, Inc. ("Treq") certain assets related to Treq's business of designing, developing, marketing, selling, servicing and maintaining software-defined networking ("SDN") technology, SDN controller software and SDN management software (the "SDN Business"). The financial results of the SDN Business are included in the Company's condensed consolidated financial statements starting on the Treq Asset Acquisition Date. On February 19, 2014 (the "PT Acquisition Date"), the Company completed the acquisition of Performance Technologies, Incorporated ("PT"). The financial results of PT are included in the Company's condensed consolidated financial statements starting on the PT Acquisition Date. |
| Principles of Consolidation | Principles of Consolidation The condensed consolidated financial statements include the accounts of Sonus and its wholly-owned subsidiaries. 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, including impairments, 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. |
| Financial Instruments | Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include cash equivalents, marketable securities, investments, accounts receivable, accounts payable and other long-term liabilities, approximate their fair values. |
| 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. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-16, Simplifying the Accounting for Measurement-Period Adjustments ("ASU 2015-16"), which eliminates the requirement to restate prior periods to reflect adjustments made to provisional amounts recognized in a business combination. Under ASU 2015-16, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, rather than retrospectively, as had previously been required. ASU 2015-16 also requires acquirers to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for the Company beginning January 1, 2016. The adoption of ASU 2015-16 is not expected to have a material impact on the Company's consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory ("ASU 2015-11"). ASU 2015-11 simplifies the measurement of inventory by requiring entities to measure most inventory at the lower of cost and net realizable value, replacing the previous requirement to measure most inventory at the lower of cost or market. ASU 2015-11 does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. ASU 2015-11 is effective for the Company for both interim and annual reporting periods beginning January 1, 2017. The adoption of ASU 2015-11 is not expected to have a material impact on the Company's consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). ASU 2014-15 provides guidelines for determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity's ability to continue as a going concern. ASU 2014-15 is effective for the Company for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The adoption of ASU 2014-15 is not expected to have a material impact on the Company's consolidated financial statements. In June 2014, the FASB issued ASU 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force) (“ASU 2014-12”). ASU 2014-12 clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent upon the entity’s satisfaction of a performance target until it becomes probable that the performance target will be met. ASU 2014-12 does not contain any new disclosure requirements. ASU 2014-12 is effective for the Company beginning January 1, 2016. The adoption of ASU 2014-12 is not expected to have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) its final standard on revenue from contracts with customers. ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the revenue model to contracts within its scope, an entity identifies the contract(s) with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to the performance obligations in the contract and recognizes revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 applies to all contracts with customers that are within the scope of other topics in the FASB ASC. Certain of ASU 2014-09’s provisions also apply to transfers of nonfinancial assets, including in-substance nonfinancial assets that are not an output of an entity’s ordinary activities (i.e., property, plant and equipment; real estate; or intangible assets). Existing accounting guidance applicable to these transfers has been amended or superseded. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the original effective date of interim and annual reporting periods by one year. As a result, public entities would not be required to apply the new revenue standard until annual reporting periods beginning after December 15, 2017. The Company is currently assessing the potential impact of the adoption of ASU 2014-09 on its consolidated financial statements. |

| Summary of restructuring accrual activity |
The Company expects that the remaining amounts accrued under the 2015 Restructuring Initiative will be paid in the fourth quarter of 2015. 2012 Restructuring Initiative In August 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 (the "2012 Restructuring Initiative"). The Company regularly reviews its restructuring accruals against expected cash expenditures to determine if adjustments are required. As a result of such reviews, the Company recorded credits to restructuring expense aggregating $1.7 million in the nine months ended September 25, 2015. This amount is comprised of a credit of $1.4 million recorded in the three months ended June 26, 2015 in connection with a settlement with the landlord of the Company's Fremont, California facility to vacate the facility without penalty or future payments and a credit of $0.3 million recorded in the three months ended March 27, 2015. The amount reversed in the three months ended March 27, 2015 is comprised of approximately $272,000 for facilities in connection with a settlement with the landlord of the Company's Dulles, Virginia facility for an amount that was lower than had previously been accrued and approximately $67,000 in connection with changes in the amounts of severance ultimately paid to certain individuals. The Company also recorded $0.1 million of restructuring expense in the three months ended September 25, 2015 related to vacating the Company's Rochester, New York facility. The Company recorded $0.7 million of restructuring expense in the three months ended September 26, 2014 and $2.2 million in the nine months ended September 26, 2014 for severance and related costs in connection with reducing its workforce. A summary of the 2012 Restructuring Initiative accrual activity for the nine months ended September 25, 2015 is as follows (in thousands):
