I have implemented a SIP User agent listening on 148.147.206.192:5060. And used express talk SipPhone ( listening on 148.147.206.192:5070 ) to initiate SIP session. The issue I am facing here is My SIP UA sends BYE message and waits for 200 OK. But 200 OK is coming on port other than 5060. Please refer to call flow below.
Is it expected behaviour ? Is there a way to force SIP client to send 200 OK for BYE on desired port number ?
