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
