I'm currently run ser with media proxy and it working fine if I force all calls
throught the the media proxy...
I want only calls destine to PSTN gateway to go through the media proxy for billing
purpose and all other calls, I just want to fix the NAT and setup the call. I dont want
the media to go throught my server if it not destine to PSTN network.
Let me know how my config should be...Am new with SER and am stuck on this. below is my
configure for NAT.
Thanks in Advance.

You could move the test on INVITE and call to use_media_proxy(); until you have reached
the sections routing to and from the gateway. Of course, calls from the gw could be
tested using if (src_ip == ip_address_of_gw).
Anyway, the idea would be to wait with the call to use_media_proxy until you are sure that
these calls are from/to the gateway.
Please remember that all incoming calls to UAs behind symmetric NAT and some combinations
with UAs behind port-restricted NAT need to be proxied. If you only proxy gw calls, some
ip-to-ip calls will fail.
