What is Media Gateway Control Protocol (MGCP)?

MGCP stands for Media Gateway Control Protocol. It represents a protocol that can be used to handle the components of a decomposed media gateway. Media gateways include endpoints on which the call agent can make, alter and remove links to create and control media sessions with several multimedia endpoints.

The call agent can inform the endpoints to identify specific events and produce signals. The endpoints automatically interact with changes in the service state to the call agent. The call agent can audit endpoints and the links on endpoints. MGCP considers a call control architecture where the call control judgement is external to the gateways and handled by external call control elements defined as Call Agents.

The MGCP considers that these call control components, or Call Agents, will synchronize with each other to transmit coherent commands and feedback to the gateways under their control.

If this presumption is disrupted, inconsistent behavior must be expected. MGCP does not represent a structure for synchronizing call agents. MGCP is a master/slave protocol where the gateways are normal to execute commands shared by the Call Agents.

Media Gateway Control Protocol is a call control protocol that can be used in VOIP connection. VOIP represents Voice over internet protocol. It supports voice communication on TCP/IP networks or the internet. Telephones and smartphones are very common things. The normal phone communications on the radio waves which do not need some IP address or web connectivity.

The voice communication is transformed on the IP-based framework. A user uses voice communication equivalent to data communication on the internet. Media Gateway Control Protocol supports the facility to create voice calls among several users on the internet or WAN.

MGCP supports the reorganization of common electronic voice communication to IP-based voice communication. The TCP/IP network supports the data shared between the users on the web. Voice communication can be completed in a similar method like data shared in the TCP/IP network.

The voice changed in the form of data packets and transferred between different devices like IP Phones. We can say the voice transformed in the form of digital data and routed from the routers in a similar way to data communication.

VOIP provides the feature of voice calls over the internet or IP network. The ordinary voice call terminology was replaced by the IP network communication system. The technology is as easy as sending a message over the internet. In the case of VOIP, the voice is divided in the form of data packets and routed via a router in the TCP/IP network.
