Abstract

This document describes an application programming interface and a corresponding protocol (MGCP) which is used between elements of a decomposed multimedia gateway. 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.

IESG Note

   This document is being published for the information of the

   community.  It describes a protocol that is currently being deployed

   in a number of products.  Implementers should be aware of RFC 3015,

   which was developed in the IETF Megaco Working Group and the ITU-T

   SG16 and which is considered by the IETF and ITU-T to be the

   standards-based (including reviewed security considerations) way to

   meet the needs that MGCP was designed to address.

Abstract

   This document describes an application programming interface and a

   corresponding protocol (MGCP) which is used between elements of a

   decomposed multimedia gateway.  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 gateways contain endpoints on which the Call Agent can create,

   modify and delete connections in order to establish and control media

   sessions with other multimedia endpoints.  Also, the Call Agent can

   instruct the endpoints to detect certain events and generate signals.

   The endpoints automatically communicate changes in service state to

   the Call Agent.  Furthermore, the Call Agent can audit endpoints as

   well as the connections on endpoints.

RFC 3435                        MGCP 1.0                    January 2003

   The basic and general MGCP protocol is defined in this document,

   however most media gateways will need to implement one or more MGCP

   packages, which define extensions to the protocol suitable for use

   with specific types of media gateways.  Such packages are defined in

   separate documents.
