Abstract

This document describes an application programming interface and a corresponding protocol (MGCP) for controlling Voice over IP (VoIP) Gateways from external call control elements. MGCP assumes a call control architecture where the call control "intelligence" is outside the gateways and handled by external call control elements.

IESG NOTE:

This document is being published for the information of the

in a number of products. Implementers should be aware of

developments in the IETF Megaco Working Group and ITF-T SG16 who are

currently working on a potential successor to this protocol.

Abstract

This document describes an application programming interface and a

corresponding protocol (MGCP) for controlling Voice over IP (VoIP)

Gateways from external call control elements. MGCP assumes a call

control architecture where the call control "intelligence" is outside

the gateways and handled by external call control elements.

The document is structured in 6 main sections:

* The introduction presents the basic assumptions and the relation

to other protocols such as H.323, RTSP, SAP or SIP.

* The interface section presents a conceptual overview of the MGCP,

presenting the naming conventions, the usage of the session

description protocol SDP, and the procedures that compose MGCP:

Notifications Request, Notification, Create Connection, Modify

Connection, Delete Connection, AuditEndpoint, AuditConnection and

RestartInProgress.

* The protocol description section presents the MGCP encodings,

which are based on simple text formats, and the transmission

procedure over UDP.

* The security section presents the security requirement of MGCP,

and its usage of IP security services (IPSEC).

* The event packages section provides an initial definition of

packages and event names.

* The description of the changes made in combining SGCP 1.1 and IPDC

to create MGCP 1.0.
