BROADSOFT AND INTERNET2 LAUNCH DISASTER RECOVERY FOR UNIVERSITIES' VOICE NETWORKS

Business Continuity Ensured Through SIP-Based VoIP Application

HOLLYWOOD, Fla., July 28, 2003 -- BroadSoft® Inc., the leading provider of hosted communications platforms, today announced the launch of a disaster recovery initiative within the Internet2 Voice over IP (VoIP) Working Group. This cooperative initiative is being led by BroadSoft, Georgetown University, Internet2, and Paetec with participating member institutions including Catholic University, Harvard, University of Pennsylvania, and Texas A&M. The objective of this initiative is to ensure business continuity and survivability using IP networks in an event that the circuit-switched public network goes down. Using Internet2 as a backup for a traditional PBX and switched network architecture offers an IP-based disaster recovery solution at a greatly reduced cost.

Universities and government agencies require uninterrupted communications to maintain lifeline services under adverse conditions. The purpose of the Internet2 VoIP disaster recovery project is to ensure business continuity and survivability via IP networks, such as the public Internet or Internet2's Abilene network, when the public switched telephone network (PSTN) goes down. Internet2's Abilene network provides a resilient and distributed IP-based disaster recovery alternative to the PSTN's traditional PBX and switched network architecture, which is more susceptible to outages.

"BroadSoft's innovative VoIP-based disaster recovery application includes an inherent self-healing nature that allows calls to be automatically re- routed to other PSTN and call-routing resources," said Christopher Peabody, project leader for the working group and IT Director for Georgetown University. "As a result, administrators can access the disaster recovery lines in response to an emergency situation, whether it's a network element failure, sustained usage spike, natural calamity or malicious activity."

According to Walt Magnussen, Co-Chair of the VoIP Working Group and Director of Technology at Texas A&M University, "The VoIP Disaster Recovery project is effective because of the close working relationship between the BroadSoft team and the participating universities, which have a shared goal of delivering an essential survivability application. We're looking forward to expanding the scope of the project to the rest of the Internet2 membership, especially since we're using a standards SIP-based approach."

The circuit-switched network, though built with highly reliable individual components, is nevertheless vulnerable to geographic disruptions, whether caused by a flash flood or terrorist activities. However, this joint initiative results in nationwide disaster recovery for any university that is part of Internet2. With the first BroadWorks platform deployed at the Internet2 point of presence at the Mid-Atlantic Crossroads (www.maxgigapop.net) on the east coast, and a second location to be rolled-out shortly, the platform is architected for robust geographic redundancy.

"Internet2's goal is to build partnerships between industry, government and academia to develop and deploy advanced Internet applications," explained Ben Teitelbaum, Program Manager for Internet2's voice and integrated communications initiatives. "We are delighted to have BroadSoft generously supporting and very actively engaged in this trial. The BroadWorks platform provides an excellent set of call control features and a high degree of voice survivability, while simultaneously serving the needs of multiple institutions."

"We're very pleased to be part of the Internet2 VoIP effort, and we've learned a lot from the experts in the working group on the disaster recovery and business continuity project," said Scott Hoffpauir, Chief Technology Officer at BroadSoft. "This application demonstrates how IP voice can provide extra value for large enterprises, such as universities, through disaster recovery as well as Centrex or PBX replacement and unified communications services."
