Callipso Selects Sonus for VOIP

SWINDON, U.K. -- Sonus Networks and Callipso today announced that Callipso is implementing a nationwide, next-generation packet voice network with Sonus Networks. Callipso is deploying Sonus' Open Services Architecture (OSA) to deliver a range of voice over IP (VoIP) services, including origination and termination, as well as Session Initiation Protocol (SIP)-based enhanced services in to its existing nationwide, voice over IP network.

"Callipso is committed to providing innovative and reliable enhanced IP services that will add value to our customers' businesses today and well into the future," said Ted Dimmer, chief technology officer, Callipso. "Sonus' field-proven voice infrastructure delivers enhanced IP services that will allow us to differentiate ourselves and build loyalty among our customers, and also enable us to expand our business opportunities into new markets."

To build out its VoIP network, Callipso is implementing Sonus' core trunking solutions including the GSX9000 Open Services Switch, the Insignus Softswitch and the Sonus Insight Management System. Callipso is currently deploying the Sonus infrastructure in five cities throughout the United States to enable a SS7 interconnection capability that will support nationwide voice services as well as SIP-based enhanced services such as prepaid calling, web-based audio conferencing and, in later deployment phases, hosted IP Centrex and IP PBX offerings. Future network plans call for the deployment of Sonus' Network Border Switching solution, which will enable Callipso to interconnect or "peer" with other domestic and international carriers using VoIP rather than circuit switching.

"Implementing innovative network technologies is a critical component of Callipso's strategy," said Michael O'Hara, vice president, marketing, Sonus Networks. "As a leader in the VoIP market, Sonus has extensive experience developing feature-rich voice networks for service providers around the globe. We are pleased to have been selected by Callipso for this network deployment and look forward to building a successful relationship."
