The main argument I'm getting is that the totag is

SER proxy responds to the CANCEL with a 200 and then a 487.
The 487 totag does not match the original 183's totag. The Via/branch
matches OK, but the developers here are relying on the totag to
match the 487 to the INVITE/183 transaction, not the CANCEL 'transaction'.
section 12.3 Termination of a Dialog:
Independent of the method, if a request outside of a dialog generates
a non-2xx final response, any early dialogs created through
provisional responses to that request are terminated. The mechanism
for terminating confirmed dialogs is method specific. In this
specification, the BYE method terminates a session and the dialog
associated with it. See Section 15 for details.
Thus, the to-tag of the 487 is irrelevant, as 487 terminates all early
dialogs of this request.

Do you know what I'm talking about? What is your opinion?
I can forward a call trace (ngrep) or ethereal if you want to see it.
Are you heading out to VON?
