MOUNTAIN VIEW, Calif. – September 20, 2005. LignUp Corporation, a provider of Web services based converged communications solutions, today announced that it has been named to the 2005 Pulver 100 list. The Pulver 100 represents private companies in the communications sector that have substantial real-world deployments, enjoy significant growth rates, and represent the future of IP communications.

"LignUp is one of the players in an industry value chain that increasingly differs from the vertically integrated telecom model of the last century,” said Jeff Pulver, founder and chairman of pulvermedia. “By exhibiting a focus on a networking industry model, open interfaces, open standards, and an innovative Web services based architecture, LignUp has joined a circle of companies that represent the future of IP communications."

The LignUp Communications Solution is a Web services based solution that includes the LignUp Communications Platform (LignUp Call Director, LignUp Media Server, and LignUp SDK), and hosted IP-PBX, voice mail, unified messaging, and auto attendant applications. LignUp's Web services capabilities allow service providers to develop and deploy an ongoing flow of new hosted applications for their service offerings, increasing their competitiveness and avoiding the threat of commoditization. More than 110 organizations in the U.S. and Japan are currently leveraging the LignUp Communications Solution.

"We are proud to be counted among the Pulver 100," said Kevin Nethercott, president and COO of LignUp Corporation. "As service providers rely on this list to identify leading solutions, we appreciate Jeff Pulver's recognition and look forward to continuing our work to ease development, enhancement, and differentiation of VoIP services."

LignUp will demonstrate the LignUp Communications Solution at Fall 2005 VON in Boston at booth #1038.
