SIP Server sends SIP Request to the client. The SIP Server inserts a different port, so that response are received on a different port. The Client sends the response on the new requested port. BIG-IP drops the packet
SIP Request will not receive the SIP Response
SIP Server wants the SIP Response to be coming on a different port.
There is no workaround.
Fix BIG-IP to process the SIP Response and send it to the SIP Server
