Hi 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
