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.
