In principle you end up with two sessions, first with port 5555,
another with 4112. The current soa model does not cope with that
easily, basically, the O/A negotiation is completed the 183, and there
is no new negotiation happening with 200.

You could hack nua_session.c not to ignore SDP, but compare it with
previous one, and if they differ, generate new offer (and ignore it)
and then feed new sdp as an answer to it.
