-- more -- Sonus Networks Reports 2002 Second Quarter Financial Results -- p.2/ "The telecommunications market remains very challenging, and continues to impact our financial results," said Hassan Ahmed, president and CEO, Sonus Networks. "During this period, we have been focused on managing our business and finances with precision and extending our market leadership. Today's announcement of Deutsche Telekom, the largest PTT in Europe, as our newest customer further validates the packet voice market, and is an important endorsement of Sonus and our packet voice solutions." Concurrent with this release, Sonus announced that Deutsche Telekom's T-Systems International division has chosen Sonus to build out its next-generation VoIP network to provide multi-national corporations with enhanced voice services (see today's press release "T-Systems International Selects Sonus Networks to Provide Packet Voice Infrastructure and Services"). T-Systems will leverage the Sonus-based network to deliver services such as global voice VPN (virtual private network) and sophisticated call center routing facilities, with additional services to follow. In May, Sonus announced that KDDI, one of the largest carriers in Japan, selected Sonus to provide packet voice infrastructure solutions to support the delivery of voice over IP (VoIP) services over KDDI's broadband network. By deploying Sonus' industry-leading media gateway, softswitch and management solutions, KDDI will be able to cost-effectively deliver a range of SIP-based voice services over its high-speed fiber optic infrastructure. During the quarter, Sonus unveiled its SMARRT(TM) Cable solution, a next-generation packet voice solution specifically geared to the requirements of cable operators (MSOs). Building on packet technology already proven in carrier voice networks, Sonus' SMARRT Cable solution is designed for carrier-grade reliability, voice quality and features, and delivers voice services in a cost-effective and flexible PacketCable(TM) architecture. To further drive the implementation of VoIP in broadband cable networks, Sonus and Motorola, Inc. Broadband Communications Sector are collaborating to create a comprehensive packet voice solution available for broadband network operators. The Motorola/Sonus end-to-end packet voice solution draws upon the extensive capabilities of two industry leaders - Motorola providing advanced IP access network solutions and Sonus providing telco-grade packet voice infrastructure products. -- more -- Sonus Networks Reports 2002 Second Quarter Financial Results -- p.3/ Also in the quarter, Sonus was named the worldwide market share leader for carrier-class packet voice equipment for the seventh consecutive quarter. Leading industry research firms In-Stat/MDR, Infonetics Research and Synergy Research Group issued first quarter 2002 market share reports confirming Sonus' continued leadership position in a number of market segments. Also in May, the Aberdeen Group released a report citing Sonus' deployment with Japanese carrier Fusion Communications as one of the most significant VoIP deployments of 2001. Today, Sonus announced that it has been named as a defendant in a securities class action lawsuit (STEINBERG V. SONUS NETWORKS, INC., ET AL., 02 CV 11315 D. Mass) alleging that the company made false and misleading statements about its products and business. Sonus has not yet filed a response to the complaint. The company believes that the claims are without merit and that it has substantial legal and factual defenses, which it intends to pursue vigorously. ABOUT SONUS NETWORKS Sonus Networks, Inc., is a leading provider of packet voice infrastructure products for the new public network. With its Open Services Architecture(TM) (OSA), Sonus delivers end-to-end solutions addressing a full range of carrier applications, including trunking, residential access and Centrex, tandem switching, and IP voice termination, as well as enhanced services.
