Enables service providers to rapidly deploy affordable, easy-to-install voice solution tailored for smaller firms

September 12, 2006 - BroadSoft Inc., a leading provider of voice over Internet Protocol (VoIP) application software, today announced at Fall 2006 VON an interoperable solution that uses its BroadWorks® SIP Trunking Solution and Avaya's one-X™ Quick Edition, a small business and branch office solution. The companies are conducting demos of the solution in the BroadSoft booth (Booth 1143) during the trade show.

BroadSoft's BroadWorks is an IMS-compliant application server suite that provides enhanced business and consumer communications services. Avaya one-X Quick Edition is a SIP-based, peer-to-peer communication solution that distributes PBX functionality through its phones. The joint BroadSoft-Avaya interoperable solution enables the capabilities service providers need to add new SIP-based offerings to their portfolio-helping them rapidly deploy affordable services specifically tailored for smaller firms. Avaya Inc. (NYSE:AV) is a leading global provider of business applications, systems and services.

"By working with BroadSoft, we are dramatically simplifying small business telephony and speeding time to market for service providers" said Geoffrey Baird, vice president and general manager, communications appliance division, Avaya. "Now the millions of companies with fewer than 20 employees can realize the features and cost-saving benefits of intelligent communications that were previously available only to much larger enterprises."

Cbeyond Inc. (NASDAQ: CBEY), a managed services provider that delivers integrated packages of voice, mobile and broadband services, currently has customers trialing the BroadSoft-Avaya solution. Chief Marketing Officer for Cbeyond Brooks Robinson said, "Using our BroadWorks server suite, we can offer our customers who have Avaya one-X Quick Edition a high quality, cost-effective method to connect to our network."

The end-to-end capabilities enabled by BroadSoft and Avaya allow service providers to offer revenue-generating packages based on the VoIP features provided by the BroadWorks application platform, including mobile integration, call centers, remote office, conferencing, auto attendant and integrated PC clients. one-X Quick Edition phones in turn house the software needed for IP telephony-automatically discovering each other when plugged into a local area network and providing PBX functionality that is fully integrated with BroadWorks VoIP features.

"Everybody wins with this solution," said David Bukovsky, vice president of products for BroadSoft. "Small businesses can work with a single vendor to give their employees access to the feature-rich BroadWorks platform via one-X Quick Edition phones. Service providers get an easy-to-sell voice solution that can be bundled with other services, such as Internet access, email and Web hosting."
