RE: [Sip] New I-D on UA loose routing

["Brian Stucker" <bstucker at nortel.com>]

Another idea to add to this topic...

Why not do something like this:

Contact: <sip:user at domain?Opaque-Params=blah>

...when handing out a URI, so that when someone creates an INVITE based
off of that contact they wind up generating:

INVITE sip:user at domain SIP/2.0
Opaque-Params: blah

Etc.

That should survive all the way to the other side.

Regards,
Brian
