Stage 2 Networks First U.S. Provider to Leverage Scalability Gained through BroadWorks Platform Run on Linux Operating System

Gaithersburg, MD, March 21, 2006 - BroadSoft, Inc., a leading provider of VoIP application software, today announced that Stage 2 Networks, a New York-based IP telephony business innovator, is using BroadSoft's VoIP application platform to support its suite of voice network services. Stage 2 is employing the BroadWorks^® platform to deliver hosted PBX services to small and mid-size enterprise customers in the New York metropolitan area and will leverage the platform to expand its services to include business trunking and wholesale services nationwide.

The first U.S. service provider to deliver services over the BroadWorks platform that runs completely on the IBM BladeCenter system running the Linux operating system, Stage 2 selected the integrated approach as a scaleable, cost-effective switching solution.

"BroadWorks' scalability and advanced features were vital factors in deciding to add Business Trunking to our service offering as well as our decision to expand nationally. We continue to rely upon BroadSoft's six 9's of reliability which typifies the quality our customers have come to expect from us. For Stage 2 Networks, being customer-centric is not just a slogan. It's our culture. And BroadSoft helps us deliver the highest quality and reliability possible to keep our customers happy."

"Stage 2 has recognized the enormous scalability benefit gained by running the entire BroadWorks platform on Linux-based hardware, enabling Stage 2 to grow both its services and its markets," said Michael Tessler, president and CEO of BroadSoft.
