    Multi-party Chat Using the Message Session Relay Protocol (MSRP)

Abstract

   The Message Session Relay Protocol (MSRP) defines a mechanism for
   sending instant messages (IMs) within a peer-to-peer session,
   negotiated using the Session Initiation Protocol (SIP) and the
   Session Description Protocol (SDP).  This document defines the
   necessary tools for establishing multi-party chat sessions, or chat
   rooms, using MSRP.
