Abstract

   This document is a proposal to add a new event/signal package to the
   MGCP (Media Gateway Control Protocol) protocol to control an ARF
   (Audio Resource Function) which may reside on a Media Gateway or
   specialized Audio Server.

   This event package provides support for the standard IVR (Interactive
   Voice Response) operations of PlayAnnouncement, PlayCollect, and
   PlayRecord.  It supports direct references to simple audio as well as
   indirect references to simple and complex audio. It provides audio
   variables, control of audio interruptibility, digit buffer control,
   special key sequences, and support for reprompting during data
   collection.  It also provides an arbitrary number of user defined
   qualifiers to be used in resolving complex audio structures.  For
   example, the user could define qualifiers for any or all of the
   following: language, accent, audio file format, gender, speaker, or
   customer.
