1. Introduction
This document provides a basic set of Media Gateway Control Protocol
(MGCP) packages. The generic, line, trunk, handset, RTP, DTMF,
announcement server and script packages are updates of packages from
RFC 2705 [38] with additional explanation and in some cases new
versions of these packages. In addition to these, five new packages
are defined here. These are the signal list, resource reservation,
media format, supplementary services and digit map extension
packages.
