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 : Multiple Dialog Usages in the Session
Initiation Protocol
Author(s) : R. Sparks
Filename : draft-ietf-sipping-dialogusage-01.txt
Pages : 26
Date : 2006-3-3
Several methods in the Session Initiation Protocol can create an
association between endpoints known as a dialog. Some of these
methods can also create a different, but related, association within
an existing dialog. These multiple associations, or dialog usages,
require carefully coordinated processing as they have independent
life-cycles, but share common dialog state.
This memo argues that multiple dialog usages should be avoided. It
discusses alternatives to their use and clarifies essential behavior
for elements that cannot currently avoid them.
This is an informative document and makes no normative statements of
any kind.

Send a message to:
mailserv@xxxxxxxxx
In the body type:
"FILE /internet-drafts/draft-ietf-sipping-dialogusage-01.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.
