MGCP

    (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   it superseded SGCP.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.
