Sonus Networks Reports Financial Results for Q4 FY2003, Fiscal Year 2003 and Q1
FY2004

     CHELMSFORD, Mass.--(BUSINESS WIRE)--July 28, 2004--Sonus Networks, Inc.
(Nasdaq: SONSE), a leading supplier of service provider voice over IP (VoIP)
infrastructure solutions, today reported its financial results for the fourth
quarter and fiscal year ended December 31, 2003, and for its first quarter ended
March 31, 2004. Sonus has restated its consolidated financial results for fiscal
years 2001 and 2002 and the first three quarters of fiscal 2003 in its Form
10-K/A filed with the Securities and Exchange Commission (SEC) on July 28, 2004.
Sonus today also filed its Form 10-Q for the first quarter of 2004 with the SEC.
Sonus will hold a conference call to review its financial results at 8:15 am
Eastern time, Thursday, July 29, 2004.
     Today's filings bring the Company into compliance with the SEC requirements
for the filing of its periodic reports. The Company received notice today from
the Nasdaq Stock Market that it has determined to delist the Company's stock
from the Nasdaq National Market effective as of the opening of the market on
Monday, August 2, 2004. The Company has notified Nasdaq that it has filed its
delinquent SEC reports. The Company has requested that its common stock remain
listed on the Nasdaq National Market because the Company is now in compliance
with Nasdaq's filing requirement and is awaiting a determination from Nasdaq.
     "Today we reported our financial results through the first quarter of 2004,
filed all the related securities filings and are once again in compliance with
the SEC financial reporting requirements. The completion of our financial review
forms a strong foundation for us to continue to build the company and expand our
position in the market," said Hassan Ahmed, chief executive officer and
chairman, Sonus Networks. "During this period in which we have invested
significant energy in our financial review, our business has continued to
thrive. We have announced new customers, extended our industry-leading solutions
further into the wireless and access markets, significantly expanded our
engineering, sales and services resources, and taken actions to strengthen our
internal controls, processes and infrastructure. We are excited about the market
opportunity for voice over IP and are confident in our ability to play a
leadership role."
     Revenues for the first quarter of fiscal 2004 were $36.5 million compared
with $9.2 million in the first quarter of 2003. Net income for the first quarter
of fiscal 2004 was $3.0 million, or $0.01 per share, compared with a net loss
for the first quarter of fiscal 2003 of $9.7 million, or $0.05 per share.
     Revenues for the fourth quarter of fiscal 2003 were $46.4 million compared
with $12.5 million in the fourth quarter of fiscal 2002. Net income for the
fourth quarter of fiscal 2003 was $6.9 million, or $0.03 per diluted share,
compared with a net loss for the fourth quarter of fiscal 2002 of $13.4 million,
or $0.07 per share. Revenues for fiscal year 2003 were $93.2 million compared
with $93.9 million for fiscal year 2002. Net loss for fiscal year 2003 was $15.1
million, or $0.07 per share, compared with a net loss for fiscal year 2002 of
$73.8 million, or $0.39 per share.

     Restatement of Consolidated Financial Statements

     As a result of the financial review, Sonus has restated its consolidated
financial results for fiscal years 2001 and 2002 and the first three quarters of
fiscal 2003 as embodied in its Form 10-K/A. As previously reported, the primary
impact of the restatements is the adjustment to the timing of revenue
recognition and certain other financial statement accounts. Principal
adjustments to revenue relate to the timing of revenue where the revenue has
been deferred and recognized in subsequent periods. In addition, other material
restatements include adjustments to purchase accounting, impairments, accruals
and deferred compensation.

     An overview of adjustments by period is as follows:

     --   2003 - Restated revenues for the first nine months of 2003 were $46.8
          million compared with $66.0 million as initially reported. Restated
          deferred revenues as of September 30, 2003 were $85.2 million compared
          with $34.0 million as initially reported. Accrued expenses as of
          September 30, 2003 were $17.5 million compared with $32.9 million as
          initially reported. Restated net loss was $22.0 million, or $0.10 per
          share, compared with $6.4 million, or $0.03 per share, as initially
          reported.

     --   2002 - Restated revenues for fiscal 2002 were $93.9 million compared
          with $62.6 million as initially reported. Restated deferred revenues
          as of December 31, 2002 were $59.8 million compared with $29.2 million
          as initially reported. Accrued expenses as of December 31, 2002 were
          $16.5 million compared with $33.4 million as initially reported.
          Restated net loss was $73.8 million, or $0.39 per share, compared with
          $68.5 million, or $0.36 per share, as initially reported.

     --   2001 - Restated revenues for fiscal 2001 were $128.8 million compared
          with $173.2 million as initially reported. Restated deferred revenues
          as of December 31, 2001 were $60.4 million compared with $13.3 million
          as initially reported. Accrued expenses as of December 31, 2001 were
          $18.4 million compared with $27.7 million as initially reported.
          Restated net loss was $635.6 million, or $3.68 per share compared with
          $645.4 million, or $3.74 per share, as initially reported.

     Sonus' restated annual financial statements are included in its Amendment
No. 1 on Form 10-K/A on file with the SEC. Investors are encouraged to read this
filing for a more complete description of the financial restatement. For the
purpose of restating its consolidated financial statements for the first three
quarters of 2003 and 2002, consistent with the restatements in the Company's
Form 10-K/A, Sonus anticipates amending its previously filed quarterly reports
on Form 10-Q for each of the first three quarters of 2003, as soon as
practicable.
     Sonus also reported that Stephen J. Nill, its vice president of business
operations and former chief financial officer, has resigned at the request of
the company.
