Sonus Networks Announces Enhancements to ASX VoIP Feature Server

WESTFORD, Mass., April 29 /PRNewswire-FirstCall/ -- Sonus Networks, Inc. (Nasdaq: SONS), a market leader in next generation IP-based network solutions, today announced enhancements to its ASX VoIP platform to triple its effective capacity, increase geographic resiliency and extend support for next generation voice over broadband, cable, 4G/WiMAX networks, as well as legacy last mile CLASS 5 deployments.

Sonus ASX is a market-leading solution for IP-based subscriber features, supporting both consumer and business segments, with deployments of millions of subscriber lines worldwide.

"Our continued investment in the ASX platform extends our leadership in the subscriber services market," said Guru Pai, chief operating officer at Sonus Networks.  "As voice over broadband solutions move to high volume deployments, scale and resiliency are of the highest importance. Our enhanced ASX platform is designed to better meet our customers' needs and create significant operational efficiencies for our customers as they upgrade their legacy networks or deploy green-field networks. Service providers can rapidly scale our standards-based distributed architecture, offer new services, and shorten time to market to gain a competitive advantage."

The enhancements to the Sonus ASX platform include:

Increased Scale and Density: Already one of the most scaleable platforms in the market, the ASX architecture now supports up to three times greater densities.  As a result, service providers can dramatically reduce the number of hardware elements required to scale the solution, reducing deployment cost and simplifying the points of management.

Enhanced Geographic Resiliency: Service providers can now deploy SIP-based voice over broadband services with multiple layers of redundancy.  The enhanced architecture sets the new standard for geographic resiliency by leveraging geographically dispersed servers that are treated as one virtual resource.

Reduced Roll-out Time: Architectural improvements further reduce the time and complexity required to roll out end-to-end solutions. The Sonus ASX seamlessly integrates with other Sonus elements including the Sonus Network Border Switch (NBS-9000) for session security, Sonus PSX centralized policy and routing engine and Sonus GSX-9000 media gateways.

The Sonus ASX VoIP platform is deployed worldwide by leading incumbent service providers, cable providers, and alternative service providers to deliver an industry leading array of consumer and business call features. With the ASX, service providers invest in a single, feature-rich platform to connect multiple types of end- points over an extensive set of last mile technologies, enhancing subscriber experience while reducing operational expense.
