Hi Markus, If first ACK is not reaching UAS, there should be retransmission of 200OK and, in response, retransmission of ACK. If I assume that UAC is sending BYE immediately after sending ACK, then this BYE should be treated normally and UAS should end the dialog. UAS and UAC have sufficient information to handle BYE. >>> Thats rite.. I have a question. Why UAC is sending BYE? If it is not user initiated activity then, there should be multiple transmission of 200Ok. And suppose UAS is retransmitting 200Ok which are not being delivered to UAC, then chances of successful delivery of ACK are very less. >>> UAC keeps sending ACK's corresponding to all 200's for quenching the >>> retrans.. but i think the problem being mentioned here is ACK not getting >>> to the other end for some reason.. (n/w issue or something).. so going fwd. >>> UAS exhausts the num of retrans for the 200's ... Now after this <as we >>> have discussed> the BYE from UAC to shut off the session.

I have a conncetion but I don't want this connection. So after the ACK I send immediatly a BYE. But the ACK is lost. What should I do now on the UAS side?
