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 : Extending the Session Initiation Protocol Reason Header for Preemption Events
Author(s) : J. Polk
Filename : draft-ietf-sipping-reason-header-for-preemption-03.txt
Pages : 19
Date : 2005-7-19
This document proposes an IANA Registration extension to the Session
Initiation Protocol (SIP) Reason Header to include in a BYE Method
Request as a result of a session preemption event, either at a user
agent (UA), or somewhere in the network using RSVP. This document
does not attempt to address routers failing in the packet path; but
a deliberate event of tearing down a flow between UAs, and informing
the terminated UA(s) with an indication of what occurred.

In the body type:

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.
