MOUNTAIN VIEW, Calif. and DRAPER, Utah – September 27, 2005. LignUp Corporation, a provider of Web services based converged communications solutions, and IP Telesis Communications, a provider of hosted VoIP business services, today announced that the LignUp Communications Solution will power IP Telesis’ hosted VoIP services for small, medium and large enterprises.

The IP Telesis service will provide hosted PBX services to organizations ranging from small companies that require dozens of phone lines to large, multi-location businesses, such as retail or restaurant chains, that need thousands of extensions. The LignUp Communication Solution includes hosted PBX, voice mail, unified messaging, auto attendant and other Web applications built on the Web services-based LignUp Communications Platform.

“After we evaluated our choices, we enthusiastically chose LignUp because it was the company that met our requirement for a software solution that lowers the cost of entry into a competitive telecom market,” said Brian Pettersen, president, IP Telesis Communications. "Because LignUp’s products minimize the up-front investments required to build VoIP infrastructure, we can get our business customers on-line cost-effectively. In addition, the LignUp solution also enables us to cost-effectively build enhanced services that will differentiate us in the marketplace as well as produce revenues with strong margins. These advantages are critical as we look to break into the VoIP market.”

The 100% software, standards-based LignUp Communications Solution can be deployed inexpensively, using off-the-shelf servers, and interoperates with any SIP compliant device including a mix of IP phones, IADs and media gateways. The solution easily integrates with billing and OSS systems to ensure revenue is captured, and it connects directly to VoIP termination services via a standard SIP handoff, eliminating the need for additional class-4 switching.

“IP Telesis’ selection of the LignUp Communications Solution validates our ability to strengthen business prospects for emerging VoIP service providers,” said Kevin Nethercott, president and chief operating officer, LignUp Corp. “By minimizing upfront capital requirements and enabling the delivery of higher margin services, LignUp makes it possible for companies to enter the VoIP marketplace and cost-effectively grow at the pace the market demands.”
