Answering a little bit of your scenario and a little bit of Francois':
1. Support must be explicit. Everything described so far makes
indication of the ability to receive an INVITE (or NOTIFY in
Francois' case) implicit in circumstances where such an
implication can be accidental. There are legitimate situations in
which any of the proposed heuristics used to perform such an
implication may legitimately exist and yet not mean that the
recipient is requesting INFO (or NOTIFY) requests.
I don't see this, in Francois' proposal at least. If an INVITE
request contains
Supported: In-Dialog-Events
Accept-Event-Packages: DTMF
(syntax is negotiable, of course)
then this is explicitly saying "You can send me events of the DTMF
event package related to this dialog and I am prepared to deal with
them". It's pretty much everything that a SUBSCRIBE has
I'd suggest further it doesn't really need to generate an initial
NOTIFY, depending on the event package.
