Hi,

I could make a call within NAT without any problem.
When I made a call from internet, I got no audio.
I have read the document

http://wiki.freeswitch.org/wiki/NAT_Traversal

and set the parameters.
vars.xml
<X-PRE-PROCESS cmd="set" data="bind_server_ip=my.server.ip"/>
<X-PRE-PROCESS cmd="set" data="external_sip_ip=my.server.ip"/>
<X-PRE-PROCESS cmd="set" data="external_rtp_ip=my.server.ip"/>
internal.xml
<param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
external.xml
<param name="ext-sip-ip" value="$${external_sip_ip}"/>
<param name="ext-rtp-ip" value="$${external_rtp_ip}"/>

Any advice?
Thanks.
Jimmy
