what is media gateway control protocol

This document addresses how the protocol functions and how it is implemented in Cisco CallManager. Implementors' Guide for the H.248 Sub-series of Recommendations ("Media Gateway Control Protocol") Superseded : H.Imp248.x (04/06) Implementors' Guide for the H.248 Sub-series of Recommendations ("Media Gateway Control Protocol") Superseded : H.Imp248.x (11/06) The Media Gateway Control Protocol MGCP is a signaling and call control communications protocol used in voice over IP VoIP telecommunication systems. Abbreviated as MGC, media gateway controller is a system used in some VoIP architectures. MGCP and Megaco/H.248 are the Media Gateway Control Protocols defined by the IETF and ITU-T for use in distributed switching environments. MGC handles the registration and management of resources at the media gateway.A media gateway controller exchanges messages with central office switches via a signaling gateway. A media gateway is a device used in the core network of a telecom network operator to provide transformation and interworking between media streams that use different network standards, communication protocols, codecs and physical connections, so that phone calls work properly between networks using different technologies.. Network operators can use media gateways to provide … Media gateway control protocol (MGCP) This protocol was the predecessor to Megaco (see Section 12.3.4) and still holds sway with a number of carriers and other VoIP users. http://www.theaudiopedia.com What is MEDIA GATEWAY? MGCP is designed to interface a media gateway controller and media gateway. Application Layer Gateways (ALGs) manage specific protocols by intercepting traffic as it passes through the security device. The decomposed multimedia gateway consists of a Call Agent, which contains the call control "intelligence", and a media gateway which contains the media functions, e.g., conversion from TDM voice to Voice over IP. Media Gateway Call Agent uses MGCP to establish and control media sessions with other multimedia endpoints. media gateway: A media gateway is any device, such as a circuit switch, IP gateway, or channel bank that converts data from the format required for one type of network to the format required for another. RFC 2705 Media Gateway Control Protocol (MGCP) Version 1.0 - The last update of the draft of this protocol. Media gateway communications protocol is used to implement a network element that provides conversion between the audio signals carried on telephone circuits and data packets carried over the Internet or over other packet networks. The protocol is text based 3 and supports a centralized call model. RFC 3435 Media Gateway Control Protocol (MGCP) Version 1.0 - A much more complete definition of the protocol. Discussion. The media gateway controller is called call agent in MGCP terminology and the media gateways can be either different types of VoIP gateways (residential, trunking, corporate, etc. It implements the media gateway control protocol architecture for controlling media gateways connected to the … (Megaco and H.248 are equivalent names for the same protocol, developed jointly between the IETF and the ITU-T; … What does MEDIA GATEWAY mean? MGCP (last edited 2008-04 … This document describes an application programming interface and a corresponding protocol (MGCP) which is used between elements of a decomposed multimedia gateway. Media Gateway Control Protocol (MGCP) is a plain-text protocol used by call-control devices to manage IP Telephony gateways. After analyzing the traffic, the ALG allocates resources to … MGCP (Ref.
