Media Gateway Control Function (MGCF)

The IP Multimedia Subsystem (IMS) MGCF is the next step in the evolution of the NGN class 4 VoIP softswitch and the first logical step in an IMS/VoLTE IP transformation strategy. It provides key functionality that supports IMS to TDM routing and interworking of media and signaling between core IMS/VoLTE, NGN VoIP and PSTN networks—the same kind of real-world environments that Communication Service Providers (CSPs) and IP Exchange (IPX) operators currently have in production today.

The ControlSwitch System MGCF is designed to make this transformation to all-IP IMS seamless and cost effective with minimal disruption to a CSP’s existing network. It also has an integrated Breakout Gateway Control Function (BGCF) that allows it to determine the most optimal way to process calls that break out of the IMS network and terminate on the PSTN.

The Dialogic ControlSwitch™ System is an IMS-ready Media Gateway Control Function (MGCF) NGN class 4 softswitch that provides a smooth migration path from existing TDM voice networks to the Next-Generation Network/IP Multimedia Subsystem (NGN/IMS) by enabling the interconnection of a mix of traditional and IMS SIP-based voice networks.
