                   draft-ietf-mediactrl-call-flows-12

Abstract

   This document provides a list of typical Media Control Channel
   Framework call flows.  It aims at being a simple guide to the use of
   the interface between Application Servers and MEDIACTRL-based Media
   Servers, as well as a base reference documentation for both
   implementors and protocol researchers.
