A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Proposal Investigation Working Group of the IETF.
Title : A Call Control and Multi-party usage framework for the
Session Initiation Protocol (SIP)
Author(s) : R. Mahy, et al.
Filename : draft-ietf-sipping-cc-framework-04.txt
Pages : 41
Date : 2005-2-22
This document defines a framework and requirements for multi-party
usage of SIP. To enable discussion of multi-party features and
applications we define an abstract call model for describing the
media relationships required by many of these. The model and actions
described here are specifically chosen to be independent of the SIP
signaling and/or mixing approach chosen to actually setup the media
relationships. In addition to its dialog manipulation aspect, this
framework includes requirements for communicating related information
and events such as conference and session state, and session history.
This framework also describes other goals which embody the spirit of
SIP applications as used on the Internet.

In the body type:
"FILE /internet-drafts/draft-ietf-sipping-cc-framework-04.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
