May 19, 2017Hi Mulham,
For the issue to get resolved backend server should always send response on the same port from where it received the request. There are 2 options
1) Backend sending response to the correct port 2) Add Via header in F5 using iRule when sending REQUEST to back end in SIP_REQUEST_SEND event in server context(clientside == 0) and delete the Via header on receiving response from backend in SIP_RESPONSE event in server context
Please share the SIP request and response if the issue still persists along with the IP headers.
Thanks
Syed Nazir
