Media Gateway Control Protocol

The Media Gateway Control Protocol ( MGCP ) is a network protocol for controlling VoIP gateways. MGCP (RFC 2705) is a master / slave protocol that the control information in clear text ( such as SIP ) transfers. The VoIP gateway acts as a slave and run by a switching unit (English: Call Control Device) controlled.

Operation

MGCP gateways are controlled by eight different control information ( commands). The control information is transmitted in clear text over UDP port 2427.

Pros and Cons

MGCP gateways are controlled by a central switching unit. The intelligence in the network is so centralized. The implementation and administration of MGCP gateways is simpler than H.323 gateways, since the central processing unit takes over the control. Unlike H.323 gateways, the central processing unit at any time a current status of each interface of a gateway.
