GAITHERSBURG, Md. -- BroadSoft, Inc., the leading provider of VoIP application software, today announced that Comstar United Telesystems, one of Russia's largest digital telecommunications operators and a subsidiary of Sistema (LSE:SSA - News), deployed BroadSoft's hosted VoIP application software to support its suite of corporate voice network services. Based on the BroadSoft® BroadWorks® platform, Comstar provides its SME and large business customers all the advanced features of an IP PBX minus the cost of owning and operating one.

In 2004 Sistema announced the creation of Comstar United Telesystems - the merger of three alternative telecom service providers to offer business customers a one-stop-shopping solution for all their information technology needs. By adding BroadSoft's hosted VoIP applications to its converged services package, Comstar is able to deliver to their more than 28,000 corporate customers a complete range of hosted PBX features including audio and video conferencing, universal voice mailbox, find-me-follow-me services, automatic secretary and user-friendly web-based portals for each user. BroadWorks also supports Comstar's Voice VPN service that interlinks a company's subsidiaries into a single manageable voice corporate network.

"BroadSoft's hosted voice services appeal to our customers because they support a rich set of compelling features, eliminate the need for a PBX and lower total cost of ownership," said Semen Rabovsky, general director of Comstar United Telesystems. "By supporting the IMS architecture and multiple applications on one platform, BroadSoft positions us to integrate our wireless and wireline services and move into new markets, such as residential, as regulations change and demand grows."
