UA1 behaves wrong - per RFC 3261 the dialog will be established by the 200 OK message (not by 180), therefore the to-tag from the 200 OK must be used.
klaus,
can you point out the section/paragraph in rfc 3261 that tells that the to-tag from the 200 ok must be used. i scanned the document for a while i didn't find it. the closest i found is this:
13.2.2 Processing INVITE Responses
If the dialog identifier in the 2xx response matches the dialog identifier of an existing dialog, the dialog MUST be transitioned to the confirmed state, and the route set for the dialog MUST be recomputed based on the 2xx response using the procedures of Section 12.2.1.
but it only mentions about recomputing the route set, not the rest of the dialog state.
