"The expanded demand for our VoIP solutions over the last several quarters and our focus on execution resulted in a strong second quarter and first half of 2005 for Sonus," said Hassan Ahmed, chairman and CEO, Sonus Networks. "We also are pleased to have expanded our customer base and to have introduced several new products reflecting an increased pace of innovation on which we will continue to build our leadership position in the industry during the second half of 2005 and beyond."

During the second quarter, the Company launched several major new products that further extend its technology leadership position. At SUPERCOMM 2005, Sonus unveiled its industry-leading solutions that will enable wireline and wireless service providers to realize the benefits of an IP Multimedia Subsystem (IMS) architecture. The Sonus IMS solution allows customers to comply seamlessly and cost effectively with the developing IMS standards and to maximize their investment by delivering converged multimedia services over their existing Sonus architecture. The Sonus IMS solution was recently honored with the distinguished Frost & Sullivan Award for Technology Innovation.

The Company also announced the introduction of the IMX(TM) Application Platform, a web-based multimedia environment that enables wireline and wireless service providers to rapidly develop, integrate, and manage enhanced telecommunication applications and services. The IMX Platform further strengthens the value proposition of the Sonus Open Services Partner Alliance (OSPA(R)) by allowing service providers to take advantage of existing applications through Sonus' OSPA partners and also to launch new innovative applications from Sonus and its partners.

Sonus also launched the GSX4000(TM) Open Services Switch at SUPERCOMM 2005. The GSX4000 is an innovative, compact VoIP switch that is designed to deliver carrier-class functionality, reliability and manageability. Developed specifically for service providers, the GSX4000 enables operators to expand the reach of their VoIP networks into new geographic regions, to launch new applications, or to deploy IP-based multimedia services. Further, the GSX4000 enables network operators to deploy a more efficient network topology that reduces costs by eliminating the need to backhaul traffic to large central locations. Based on the award-winning GSX9000(TM), the GSX4000 allows service providers to cost-effectively extend the reach of their network boundaries with the same carrier-class functionality that is the hallmark of Sonus' products.

Continuing to expand its worldwide customer base, Sonus announced that Jupiter Telecommunications Co., Ltd. (J:COM) is implementing the Sonus platform as the foundation for its new VoIP network in order to deliver enhanced residential voice services to consumers throughout Japan. In conjunction with the deployment of their network, J:COM is also one of the first Sonus customers to deploy the IMX Application Platform.

Following an important ruling by the Federal Communications Commission that requires VoIP service providers to supply Enhanced 911 (E-911) emergency calling capabilities to their customers as a mandatory feature of their service, Sonus announced its continued support of the delivery of these critical services to consumers through seamless connectivity to the Public Switched Telephone Network (PSTN). The Company also reported that several Sonus customers, including Level 3 Communications, are already utilizing Sonus' platform to support delivery of E-911.

During the second quarter, Sonus continued to focus on expanding its global presence through strategic partnerships. The Company announced partnerships with NK Networks to address the market opportunity in Western Europe, and with TFJY to expand the Company's distribution channel in China. In the U.S., Sonus announced its first major alliance with a major consumer electronics retailer, Belkin Corporation. Sonus and Belkin have successfully completed interoperability testing between Sonus' Voice over Broadband (VoBB) solutions and Belkin's line of VoIP broadband phone adapters, enabling service providers and consumers to simplify the configuration and provisioning process for consumer VoIP systems.

On June 8, 2005, Sonus announced that it received written notification from the Securities and Exchange Commission regarding the formal inquiry that the SEC undertook in connection with the Company's previously announced independent investigation of its financial reporting. The SEC notified the Company that its investigation had been terminated and that no enforcement action had been recommended.

"Looking ahead, the market for next-generation packet voice equipment continues to expand. Our continued product leadership and solid market momentum highlight our unique strategy for addressing the convergence of the world's communications infrastructures. We are pleased with the decision by network operators around the world to rely on Sonus for the development of their voice networks. We believe that this underscores our position in the market and our ability to continue to lead the market's evolution," concluded Ahmed.
