Abstract
This document provides a basic set of Media Gateway Control Protocol
(MGCP) packages. The generic, line, trunk, handset, RTP, DTMF (Dual
Tone Multifrequency), announcement server and script packages are
updates of packages from RFC 2705 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.
