A Media Gateway terminates voice calls on inter-switch trunks from the public switched telephone network, compresses and packetizes the voice data, and delivers compressed voice packets to the IP network. For voice calls originating in an IP network, the MG performs these functions in reverse order. For ISDN calls from the PSTN, Q.931 signaling information is transported from the MG to the Media Gateway Controller for call processing.

Media Gateway Controller

A Media Gateway Controller (MGC) handles the registration and management of resources at the Media Gateways. An MGC may have the ability to authorize resource usage based on local policy. For signaling transport purposes, the MGC serves as a possible termination and origination point for SCN application protocols, such as SS7 ISDN User Part and Q.931/DSS1. T. Because vendors of MGCs often use off-the-shelf computer platforms, an MGC is sometimes called a softswitch.
