I-D ACTION:draft-ietf-sip-connected-identity-04.txt

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		: Connected Identity in the Session Initiation
Protocol (SIP)
	Author(s)	: J. Elwell
	Filename	: draft-ietf-sip-connected-identity-04.txt
	Pages		: 24
	Date		: 2007-1-17
	
Because of retargeting of a Session Initiation Protocol
(SIP) dialog-
   forming request (changing the value of the Request-URI),
the User
   Agent Server (UAS) can have a different identity from
that in the To
   header field.  This document provides a means for that
User Agent
   (UA) to supply its identity to the peer UA by means of a
request in
   the reverse direction and for that identity to be signed
by an
   Authentication Service.  The same mechanism can be used
to indicate a
    change of identity during a dialog, e.g., because of
some action in
   the Public Switched Telephone Network (PSTN) behind a
gateway.  This
   document normatively updates RFC 3261 (SIP).

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

Internet-Draft.
