Hi!<br>
<br>
I tried to establish connection between Freeswitch and external
gateway which is located behind NAT.<br>
<br>
NAT-gateway is configured to do ip/port forwarding.<br>
<br>
RTP session can't be established. With tcpdump & wireshark <span

Freeswitch answered to local ip-address of a gateway which used in
sip "contact" header. Is it possible to say Freeswitch to use public
ip-address which is in the field "from" instead?<br>
