[Serusers] NAT and forward to PSTN

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
