[Freeswitch-users] Internal IP showing in SDP

[Matt Broad]

Hi,

does it make any difference if my internal IP address is being sent in 
the SDP connection information?  I have 2 sip providers where 1 I can 
bridge calls and receive audio and 1 that I can bridge calls but get no 
audio.

Even with the below settings the SDP message body contains c=IN IP4 
192.168.1.1.

I have vars set as:
<X-PRE-PROCESS cmd="set" data="external_rtp_ip=my.ip.goes.here"/>
<X-PRE-PROCESS cmd="set" data="external_sip_ip=my.ip.goes.here"/>

I have setup the external profile as follows:
<param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
<param name="ext-sip-ip" value="$${external_sip_ip}"/>

running sofia status profile external gives (replace 0.0.0.0 with the 
real external IP declared in vars):
