Note that even after this transaction is terminated with a 2XX final response, it is still possible for additional dialogs to be created through receipt of additional 2XX responses from different UAs. This is due to the transport processing described in section 18.1.2 that will forward "stray" responses (i.e. responses for which there is no client transaction) to the UA core.

Hi all again,
just when I digged deeper into the protocol behavior I found the root of a possible misunderstanding on my side, causing my previous question.
The principal question is now:
An INVITE request at a UAC creates exactly one transaction (one branch Id in Via header). If several provisional responses from different UAS (different To-tag) are received by the UAC each response creates a different dialog. But these different dialogs are handled by exactly one transaction at the UAC.
Please confirm my assumption.
Franz
