MGCP
The physical and logical sides of a softswitch need to be interconnected in order to establish communication between the media gateway and the media gateway controller. The media gateway protocol sends commands to the media gateway under the master/slave arrangement by using two protocols. One protocol is the MGCP, which was developed by the IETF and documented in RFC 2705; it is documented in its updated version in RFC 3435.
Gateways that can employ this protocol include trunking gateways present between telephone and VoIP networks; voice over ATM gateways; residential gateways that provide a RJ11 interface to a VoIP network; and other such gateways. The information between the media gateway controller and the media gateway can be categorized as either events or signals. The two categories are supported by endpoints such as telephone or video systems. MGCP commands are used for used for the communication between the call agents and the gateways. The commands include EPCF, RQNT, NTFY, CRCX, MDCX, DLCX, AUEP, AUCX, and RSIP.
