Can you also attach the original INVITE call flow along with re-INVITE?
That can help to compare the SDP versions, CSeq etc.
Also, if everything turns out to be OK, then there may be some policy (private)
based on which it might be rejecting!

I'm havin a problem sending a re-invite message to change the current
SDP-Session.
The Reinvite itsself causes the receiver to generate an OK message with
its SDP. But after receiving the following Request ACK it just generates a
BYE and ends. Does anyone see the problem? Is the Reinvite correct? Are
the CSeqs ok?
many thanks in advance!!
