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.
