Hi Seckin, 

Please share what kind of configuration you had made in F5 for SIP.

From the packet trace below is the message from F5 and Backend SIP server
F5 (10.10.100.4:35365 ) ==> SIP OPTIONS ==>SIP server (10.10.104.49:50001)
SIP server (10.10.104.49:50001) ==> 200 ==> F5(10.10.100.4:5061)

The backend server is not sending the response back on the same port from 
where it has received the request.

Solution: 
1) Either backend server has to send the respond back on the same port as 
received in request
2) Add iRule in F5 to add Via header with correct port number.
