Global communications have radically improved due to the introduction of the Internet, broadband, and mobile technologies and devices, but true convergence of user experiences and the networks that enable them remains a challenge for many operators and enterprises.  Convergence requires intelligent, advanced call and session control platforms that connect diverse networks, media types, signaling, protocols, architectures, and devices together to create a seamless experience for users.

GENBAND’s C20 Call Session Controller is the world’s leading IP and IMS communications convergence platform for voice and multimedia.  Integrating significant new investment in intelligent innovations, the software-centric C20 utilizes the GENBAND GENiUS commercial-off-the-shelf platform and provides call and session control, network connectivity, switching, signaling and protocol interworking, core and edge interworking, unified multimedia communications, and applications for wireless, wireline, cable, and enterprise markets.

Deployed globally to enable new multimedia services, the C20 grows revenue and ARPU, converges disparate networks, replaces costly legacy switching, and is the cornerstone of new core networks.  It is fully carrier-grade and network-hardened, having switched billions of calls and sessions for business and residential customers.  The C20 is a key element in many of GENBAND’s Solutions including IMS, VoLTE, SIP Trunking, IPX, Peering, and Intra-Network Interconnect.
