[Serusers] RTP Proxy Help - One way Audio

Hey Guys, I am having issues with One way Audio for outgoing phone calls from my SIP phones. It works fine for Incoming, but outgoing audio is not working. Also, Outgoing works fine if I put my SIP phone on an Internet IP address, but if it's NAT'd then I get the 1 way audio on outgoing calls. I am using the default nathelper module config, but I have hacked it a bit and maybe my changes are causing the problem? I had to use t_relay_to_tcp for our PSTN gateway and so I had to change the routing around a little. Prior to today I was using SerMediaProxy (AG Projects), but I switched to PortaOnes rtpproxy just to make sure that there wasn't a version incompatibility problem. I have also attached my current ser.cfg file. Anyone have any suggestions? Or should I change the routing in my ser.cfg file? or would that make a difference? Any help would be greatly appreciated.
