Callipso Selects Sonus Networks for VoIP

Callipso is deploying Sonus Networks' Open Services Architecture (OSA) in its national network to deliver a range of VoIP services, including origination and termination, as well as SIP-based enhanced services. Specifically, 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 U.S. 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.
