Media Gateway Control Protocol

In computing, Media Gateway Control Protocol (MGCP) is a protocol used within a Voice over IP system. MGCP is defined in an informational (non-standard) IETF document, RFC 3435, which obsoletes an earlier definition in RFC 2705. It superseded SGCP[?].

MGCP is an internal protocol used within a distributed system that appears to the outside world as a single VoIP gateway.

This system is composed of a Call Agent, and a set of gateways, including at least one "media gateway[?]" that performs the conversion of media signals between circuits and packets, and at least one "signaling gateway[?]" when connected to an SS7 controlled network.

The "approved" IETF protocol for the same purpose, although not as widely implemented as MGCP, is Megaco[?], defined in RFC 3015.
