Hi Marian,

... I'm afraid that now you got me really confused. This is a new world to me, and it's not easy.

Hi John,

depends of your gateway - if it supports symmetric RTP or not. If yes, you don't need to use rtpproxy for calls to GW, just call: fix_nated_sdp("1"); which will add "direction=active" to SDP. If the GW doesn't support this, use the same approach as for SIP-to-SIP calls

Best regards, Marian

Hi! SER is running in my Fedora Core 3 box. I've registered in my SER two IP phones located behind NAT, used the example nathelper.cfg script.

How could I manage to forward calls to a PSTN gateway, example all calls beginning by "0..." ? What are the script modifications?

Thanks john
