Sonus Supports IMS

CHELMSFORD, Mass. and CHICAGO -- Today at SUPERCOMM 2005, Sonus Networks (Nasdaq: SONS), a leading supplier of service provider voice over IP (VoIP) infrastructure solutions, announced that it is delivering 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 seamlessly and cost effectively comply with the developing IMS standards and to maximize their investment by delivering converged multimedia services over their existing Sonus architecture.

"Today's service providers are tasked with the significant challenge of building new revenue streams, improving margins, and attracting new users. Converged networks were originally viewed simply as a way to reduce operating expenses, but the real potential for service providers lies in the rollout of innovative multimedia services," said Hassan Ahmed, chairman and CEO, Sonus Networks. "IMS is the industry's first framework that allows wireline and wireless operators to leverage the disruptive force of broadband, breaking down the former barriers to service delivery and opening the door for the delivery of new services. The power of IMS is that it allows for a truly presence-enabled network and represents a profound change in the way service providers offer communication services."

The Sonus IMS solution builds on the proven benefits of Sonus' architecture, which has been deployed in service provider networks for nearly six years and today supports approximately 12 billion minutes of traffic per month. Key components in the Sonus IMS solution include its existing products: the GSX family, PSX, SGX, ASX and Insight Management Systems.
