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.
