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.
