Hi, I have a problem about 487 retransmit... After caller get a 18x from ser proxy, we cancel the call, we could see caller UA send a CANCEL message and get a 487 message from proxy. UA get 487 message then reply a ACK.. but proxy still send next 487 again and again. We check called party, no such problem, only one 487 received. Could anyone give me a hint? best regard Kaiser
