Title : Private SIP Extension for Original Dialog Identifier
Author(s) : E. Henrikson
Filename : draft-henrikson-sip-original-dialog-id-02.txt
Pages : 9
Date : 22-May-02
This memo describes a private extension to SIP in the form of a
P-Original-Dialog-ID header. The header is used to correlate two
different dialogs across a B2BUA that is non-transparent to
dialogs. The contents of the header identify the original dialog
(Call-id, From tag, To tag) associated with the SIP entity that
inserted the header into a request. When the same instance of the
header is received at that SIP entity in a different request, then
it is used to correlate the two different dialogs.

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.
