BOCA RATON, Fla. — July 27, 2005 — Siemens Communications, Inc., today announced the creation of a new strategic relationship with General Bandwidth and is leveraging the company’s G6 Universal Media Gateway as an integral component of the Siemens Next Generation Exchange (NGE) offering for U.S. service providers. The Siemens® NGE portfolio is a carrier-grade, standards-based solution designed to give service providers a cost-effective way to introduce new voice over Internet protocol (VoIP) services over existing legacy networks.

General Bandwidth is a leading VoIP manufacturer of equipment and applications that enable rapid deployment and new service revenue generation over broadband networks. As part of the new strategic relationship, Siemens Venture Capital (SVC), a $600 million corporate venture organization of Siemens AG, is increasing its existing equity investment in General Bandwidth. SVC originally invested in General Bandwidth in 2001.

The Siemens NGE solution, designed for U.S. service providers, is a fully integrated offering that includes the Siemens SURPASS® softswitch and integration services from Siemens, along with General Bandwidth’s G6 Universal Media Gateway. The Siemens NGE solution is scalable up to 100,000 lines and offers multiple services on the same SURPASS platform, including residential and business services.

The NGE solution complements Siemens’ family of SURPASS NGN solutions including Voice over Broadband (VoBB), Hosted Office™ (BC) and Voice over Cable (VoC). The offering can also become a building block in an Internet Protocol (IP)-based Multimedia Subsystem (IMS) fixed mobile convergence environment.

By incorporating General Bandwidth’s G6 Universal Media Gateway, Siemens will provide both line and trunk media gateway functions on a single platform. Enhanced emergency standalone capabilities are also integrated into the G6 platform, enabling the remote G6 gateway to maintain emergency and local community calling in the event of lost connectivity to the central softswitch.

General Bandwidth’s G6 platform scales to meet the needs of distributed softswitch deployments using industry standards-based protocols such as GR-303, TR-08, SS7 IMT, CAS, PRI and E911. As the access network evolves to deliver broadband services, the same G6 platform can simultaneously perform as a trunking media gateway supporting IP protocols such as SIP, MGCP and H.248.

“Service providers who want to displace legacy Class 5 networks want assurance that investments in IP will scale as they migrate for full VoIP and IMS architectures,” said Charles Vogt, General Bandwidth’s president and CEO. “The Siemens SURPASS hiQ softswitch and the General Bandwidth G6 Universal Media Gateway are each designed for reliable, scalable, carrier-grade network environments, creating a compelling offering for service providers who want to make a circuit-to-packet transition without disrupting existing service offerings.”

“The benefit of open standards is that service providers can always choose the best solution for their businesses,” said Harald Braun, president of Siemens Carrier Networks, Siemens Communications, Inc. “With the Siemens NGE solution, service providers also benefit from industry-leading experience in deploying fully integrated IP solutions.”
