CSC SELECTS BROADSOFT'S BROADWORKS PLATFORM TO PROVIDE HOSTED COMMUNICATIONS TO FEDERAL GOVERNMENT CUSTOMER

GAITHERSBURG, MD, April 29, 2003 -- BroadSoft® Inc., the leading provider of hosted communications platforms, today announced that Computer Sciences Corporation (NYSE: CSC) recently deployed a BroadSoft solution to deliver hosted communications services to a major federal agency customer. CSC, which provides hosted voice and data services to several federal agencies, selected BroadSoft's BroadWorks® solution.

"CSC has been providing end-to-end solutions to its clients for more than 43 years," said Peter Himmelberger, a vice president of CSC's Federal Sector business unit. "Before deploying a traditional switch-based telephone system for a recent customer, we worked through several business cases. Because the client's system services multiple locations, BroadSoft's IP-based technology was substantially more cost-effective than the switch-based option. We realized that a transition to the BroadWorks solution could better meet this customer's needs, and we acted accordingly."

BroadSoft has now announced 16 customers that are using the award-winning BroadWorks hosted communications platform, further establishing its market leadership with the most announced customers in its market segment.

"This relationship reinforces our strategy of serving the large enterprise through a variety of IT services organizations and managed service providers," said Michael Tessler, president and CEO of BroadSoft. "BroadWorks provides the reliability and security that government agencies require as they upgrade to advanced communications services. Our platform also gives these agencies access to the full range of next-generation communications applications."

BroadWorks provides a comprehensive range of applications including Hosted PBX, IP Centrex, and Voice VPN. BroadWorks is uniquely capable of providing these applications with the reliability, redundancy, scalability, and regulatory capabilities required to deliver carrier-class service. BroadWorks enables service providers to increase top-line revenues by offering enhanced services to enterprise customers. BroadWorks also reduces operational expenditures by empowering enterprises to manage their own moves, adds and changes via the patented CommPilot™ web portal. The open, standards-based environment of BroadWorks provides maximum flexibility for service providers to customize their offering.
