             A User Agent Profile Data Set for Media Policy
              draft-camarillo-rai-media-policy-dataset-03

Abstract

   This specification defines an XML document format to describe the
   media properties of Session Initiation Protocol (SIP) sessions.
   Examples for media properties are the codecs or media types used in
   the session.  This document also defines an XML document format to
   describe policies that limit the media properties of SIP sessions.
