Can you please explain what a "re-INVITE without the To tag is"? It makes no sense, a dialog mathing request MUST contain the SAME From tag, To tag and Call-ID of previous transactions in same dialog. If a new request hasn't To tag then it's not an in-dialog request (so it's not a re-INVITE). Exactly. Since it has no to-tag, it is a dialog-forming request. It happens to have the same Call-Id as existing dialogs, but that can happen as a consequence of forking anyway. So it must be processed as a dialog-forming INVITE. In regard to the "transaction layer" and "core", etc., those are parts of the model described in 3261, but are not prescribed components of SIP processing, as they are not visible outside the SIP element.
