BroadSoft Platform at Core of Unient's Turnkey Wholesales VoIP Service for European Carriers

Off-the-Shelf Solution Enables Carriers to Launch Branded IP Centrex and Residential Broadband Services in Weeks

GAITHERSBURG, MD, May 16, 2005 - BroadSoft®, Inc., the leading provider of VoIP application software, today announced that Unient Communications a.s., a pan-European telecommunications systems provider, is using the BroadSoft BroadWorks VoIP application platform to offer European carriers the most comprehensive wholesale IP Centrex, hosted PBX and residential broadband service. Unient's viphone service bundles BroadWorks' complete range of advanced voice features, such as user-configurable voicemail-to-email and find-me, follow-me services, with extensive professional services, including training, portal development, billing and localization for Europe's multi-lingual market.

As a BroadWorks systems integrator for major incumbents, such as Slovak Telecom, Unient provides European carriers a smooth migration path from a shared to a dedicated VoIP network solution. By minimizing CAPEX (capital expenditures) and providing a full suite of professional services, Unient's viphone wholesale service removes barriers to entry for small carriers while enabling large carriers to focus on customer acquisition and long-term strategies rather than technical implementations of a VoIP service.

"BroadSoft is the clear leader in the hosted VoIP space in Europe," said Pavel Chlupácek, chairman of Unient. "BroadWorks' best-in-class technology and platform architecture readily supports wholesale offerings and third-party development, including localization, which is crucial for this market. By choosing BroadSoft, we're able to deliver wholesale services that carriers can launch quickly to begin earning revenue in their target market."

"The wholesale model is essential in the European market for carriers who want to launch localized hosted VoIP services quickly without the challenges of building a network," said Michael Tessler, CEO and chairman of BroadSoft. "With their unique combination of wholesale offerings and extensive professional services, Unient is successfully serving this market by enabling carriers to get to market as quickly and simply as possible."
