Howdy,
In an effort to avoid endless thrashing, I will be updating the Session-ID
draft to only be about troubleshooting use.
For dialog matching issues, I have followed Adam's advice and submitted a
separate draft to update RFC 3261, linked below.
This issue will only get worse, and the code changes to do this should be
fairly small for most folks, I would think.
And it's only 6 pages, so we should be able to agree on this in about 3 years.
:)
A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : A Secure Call-ID for the Session Initiation Protocol
(SIP)
Author(s) : H. Kaplan
Filename : draft-kaplan-sip-secure-call-id-00.txt
Pages : 6
Date : 2009-03-04
Many SIP devices generate Call-ID values which contain their system IP Address,
due to examples and normative text in RFC 3261. This has led to some
middleboxes, such as SBC's, to change the Call-ID for security reasons. This
draft updates RFC 3261 to require SIP User Agents to generate benign Call-IDs,
in such a manner that they can be detected as secure and not need to be changed.
