BroadWorks Platform Underpins ATX's VoIP Services on Mid-Atlantic Network

Gaithersburg, MD, February 22, 2006 - BroadSoft, Inc., the leading provider of VoIP application software, today announced that ATX Communications, a leading provider of communications technologies, is using BroadSoft's VoIP application software as the platform to deliver its high-value ATX CoreFlexSM VoIP service to small and mid-sized businesses in the Mid-Atlantic region.

"ATX is actively committed to strengthening customers' competitive advantages by solving problems in three fundamental business areas-infrastructure, security and productivity," said Lou Sommi, director of Product Management for ATX. "As the foundation for our VoIP services, we chose the BroadWorks® platform because it offered an integrated solution with the ability to deliver multiple services on a single platform. BroadWorks lets us offer quality VoIP services while improving the efficiency of our customers' systems and workforces, as well as enhancing communication both internally and externally. BroadSoft's professional and knowledgeable support has also been crucial in bringing our service to market quickly."

"One of ATX's strengths is close collaboration with customers to understand their requirements and to develop advanced communications services and solutions based on those needs," said Michael Tessler, CEO and president of BroadSoft. "With the launch of the CoreFlex service, ATX is well positioned to expand its technology offerings to include cost-effective, IP-enabled applications that help customers leverage the benefits of voice and data convergence."
