From: "Vikram Chhibber" <[EMAIL PROTECTED]> I strongly feel that IETF should define a standard where media-description is defined to propagate SIP MESSAGE as session-mode.
Once you've established a dialog, any conforming proxy will propagate in-dialog MESSAGE requests. The only question is how to establish the dialog. We've been discussing using INVITE, but it would probably be better to establish the dialog using SUBSCRIBE. In any case, it appears that you must have both the initiating and terminating UAs understand the use of MESSAGE that you contemplate, so they can priorly agree on how to set up the dialog. (Is this a place to use the regretted INFO method?) So the only compatibility question is whether a proxy will work correctly as an intermediate. And as long as you adhere to the rules for in-dialog requests, you should have no trouble with that.
