F5 does return back to client SIP 200 OK message
Hi all,
I have configured F5 device V12.1.0 Hotfix 2 with HA mode. Configuration looks ok, but SIP service that i configured is not working as expected. F5 device does not return SIP 200 OK message to the client, and f5 device is working routed mode and SNAT is not open. Backend servers has static route to the client side to prevent asymetric routing. You can find unsuccessful packet trace as follows;

Could please confirm that F5 device can manage SIP traffic successfully ?
