          An Interactive Voice Response (IVR) Control Package
                for the Media Control Channel Framework

Abstract

   This document defines a Media Control Channel Framework Package for
   Interactive Voice Response (IVR) dialog interaction on media
   connections and conferences.  The package defines dialog management
   request elements for preparing, starting, and terminating dialog
   interactions, as well as associated responses and notifications.
   Dialog interactions are specified in a dialog language.  This package
   defines a lightweight IVR dialog language (supporting prompt
   playback, runtime controls, Dual-Tone Multi-Frequency (DTMF)
   collection, and media recording) and allows other dialog languages to
   be used.  The package also defines elements for auditing package
   capabilities and IVR dialogs.
