Media Gateway Control Protocol

communications, protocol (MGCP) A protocol used within a

Voice over IP system. MGCP is an IETF work in progress,

it superseded SGCP.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 "signalling gateway" when

connected to an SS7 controlled network.
