If you want we could ask in SIP-implementors, but I've already debated
about this exact question there and the conclusion was that the SDP

change during the same early-dialog (183...200 with same To_tag).
Best regards.
I've already open a new thread in SIP-implementors. I hope I could
convince you ;)

Iñaki,
You can try the attached patch, which makes B2BUA use different To tag
OOPS, sorry, the patch in the previous message is incomplete. Attached
is the correct one.
