CFX-5000 SIP session control

CFX-5000 central controller for the IMS/SIP core

The CFX-5000 controls every service in an all-IP network and makes possible new subscriber services such as VoLTE, VoWiFi, RCS and WebRTC.

Acting as central control core, the CFX-5000 offers session and service control, all using standard interfaces and application triggering mechanisms. Yet it remains flexible enough to allow rapid introduction of new, ARPU-boosting services and applications.
