The Cirpack IMS core network aims at implementing SIP-based rich communication services for telecom operators. It operates SIP-based voice, video and messaging services for subscribers over fixed or wireless broadband access. Subscribers can access services from a variety of devices such as mobile, tablet, PC, smartphone, and regular web browser.
All these functions are integrated on the same software platform to be provisioned and operated as a single product.
As the migration of the networks from TDM to VoIP is accelerating, deploying the IMS Core network paves the way to have full VoIP networks where the SIP protocol is used on the access, the core network, as well as on the interconnect side.
Our IMS core network offers to network operators a solution for interactive multimedia services, from regular voice calls to multimedia and enriched communications. It is completed with our Multimedia Telephony Application Server for complete service offer, and comes also with an OTT application server providing access to the service through a Web browser access and mobile client application.
The IMS core network is an Interrogating Call Session Control Function (I-CSCF), Serving Call Session Control Function (S-CSCF), and a Home Subscriber Server (HSS) for fixed devices, also named User Profile Server Function (UPSF).
