Other investors in this round include Tekelec, Bessemer Venture Partners, Charles River Ventures, Columbia Capital, and Crescendo Ventures.

This additional funding comes at a time when BroadSoft's sales are increasing both in the United States and abroad. BroadSoft will use the funding principally to expand its sales activities worldwide. BroadSoft is leading its market with the largest number of announced customer deployments, with nine customers announced to date.

"Carriers worldwide are beginning to recognize the value of IP telephony services in terms of increasing revenue/profits while decreasing infrastructure and operations costs. BroadSoft offers the first carrier-class solution for these services, providing a level of operational support, management, reliability and scalability that the 'tier one' carriers demand. With the largest installed base of customer deployments, BroadWorks is a field tested and proven product that delivers telephony services 'day-in and day-out' to satisfied carrier customers throughout the globe," said Frank Dzubeck, president of Communications Network Architects Inc., a leading communications analyst firm.

"By providing carrier-class reliability and scalability, lower operations costs, and a comprehensive portfolio of business communications applications, BroadSoft is driving the acceptance of IP telephony services by US as well as global service providers and their enterprise customers," said Rich McGinn, general partner at RRE Ventures. "The company's strong management team, sound business strategy and superior product capabilities have convinced me that BroadSoft will realize its enormous growth potential and attracted RRE to make this investment."

"BroadSoft offers service providers the opportunity to expand revenue streams with new and innovative services while lowering operations costs. This combination gives carriers what they need to be successful and maintain profitability," said Joseph R. Zell, general partner at Grotech Capital Group. "Grotech invested in BroadSoft because we have seen no other vendor that can offer the combination of carrier-class reliability along with cost-effective operations capabilities. We pride ourselves on investing in successful companies, and we believe that BroadSoft fits that requirement."

McGinn and Zell, who are both joining BroadSoft's Board of Directors, have played major roles in bringing innovative new services to the carrier market. McGinn has spent more than 30 years in global communication systems, networking and technology industries. He is the former Chairman and CEO of Lucent Technologies as well as president and CEO of AT&T's Network Systems Group and president of AT&T Computer Systems. He also served as president of AT&T's Data. Zell has more than 20 years of experience in communications and data networking. He spent nine years with US West Communications (now Qwest Communications) and was instrumental in building its !NTERPRISE Networking Division, for which he served as president his last four years. Most recently, Zell was CEO of Convergent Communications.

"The strong validation this significant investment provides BroadSoft is very, very encouraging - especially coming at such a challenging time for the economy in general and telecommunications in particular " said Michael Tessler, president and CEO of BroadSoft. "The depth of experience that Rich brings from Lucent and AT&T and that Joe brings from US West, Convergent Communications and Wiltel will be invaluable for BroadSoft."
