MOUNTAIN VIEW, CA and RICHARDSON, TX - Carrius Technologies, Inc., an innovator in Voice over IP (VoIP) switching and intelligent gateway solutions, and LignUp Corporation, a provider of web services based VoIP communications solutions, today announced a partnership to provide a comprehensive VoIP communications platform targeting business and residential customers.

Carrius and LignUp have completed interoperability testing, bringing LignUp's LignUp Communications Platform and Carrius' Compleat-200 Intelligent IP Gateway together in a comprehensive, cost-effective solution. The LignUp Communications Platform offers IP-Centrex, Voice Mail, Unified Messaging, and IVR applications. The Compleat-200 combines media gateway, signaling gateway, and call control functions in a single scalable platform.

"We are excited to partner with LignUp to address a previously underserved market requiring scalable, cost-effective, and end-to-end VoIP solutions," said Allen Adams, CEO of Carrius. "The LignUp Communications Platform allows for rapid customization and enables service providers to quickly and easily develop enhanced services, differentiate themselves in the marketplace, and drive sustainable revenue."

"By joining with Carrius, we are lowering the entry barriers for service providers desiring to offer Voice over Broadband solutions," said Kevin Nethercott, President and COO, LignUp Corp. "Carrius' integrated solution eliminates the need for service providers to select, integrate, and deploy separate media gateways, signaling gateways, and softswitches."

Carrius and LignUp will demonstrate the solution live, at Spring 2005 VON, in the Carrius booth (1228) and LignUp booth (1329).
