A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Protocol Working Group of the IETF.
Title : Request Authorization through Dialog Identification in the Session Initiation Protocol (SIP)
Author(s) : J. Rosenberg
Filename : draft-ietf-sip-target-dialog-01.txt
Pages : 16
Date : 2005-7-20
This specification defines the Target-Dialog header field for the
Session Initiation Protocol (SIP), and the corresponding option tag,
tdialog. This header field is used in requests that create SIP
dialogs. It indicates to the recipient that the sender is aware of
an existing dialog with the recipient, either because the sender is
on the other side of that dialog, or because it has access to the
dialog identifiers. The recipient can then authorize the request
based on this awareness.

In the body type:
"FILE /internet-drafts/draft-ietf-sip-target-dialog-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.
