_________________________________________________________________________Hi,
In the default configuration, the internal profile listen port 5060 and external profile listen port 5080.
And follow the setting in http://wiki.freeswitch.org/wiki/NAT_Traversal
vars.xml
<X-PRE-PROCESS cmd="set" data="bind_server_ip=59.120.xx.xx"/>
<X-PRE-PROCESS cmd="set" data="external_sip_ip=stun:stun.freeswitch.org"/>
<X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.freeswitch.org"/>
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}"/>
When user make a SIP call from public network using external profile(5080), he encountered no audio.
Here is the SDP of 200 OK from FS to user.
v=0
o=FreeSWITCH 1366781127 1366781128 IN IP4 10.0.110.33
s=FreeSWITCH

I can't figure out which parameters in sofia profile or in dialplan make port 5060 set the public IP in SDP and work fine.
Any advice?
Thanks in advance.
