Hi<br>
<br>
our FS is on public ip but the voip server to which trunk is made
(SFB) is behind NAT.<br>
<br>
So the issue is that in SDP is private ip and FS sends RTP to this
private ip, it does not change to src ip from which sip request was
received.<br>
<br>
Remote SDP:<br>
<small>2016-04-21 08:04:00.954752 [DEBUG] sofia.c:5614 Remote SDP:<br>
v=0<br>
o=- 46176 1 IN IP4 172.16.2.3<br>
s=session<br>
c=IN IP4 172.16.2.3<br>
b=CT:1000<br>
t=0 0<br>
m=audio 31200 RTP/AVP 8 101 13<br>

a=rtcp:31201<br>
a=<a class="moz-txt-link-freetext" href="label:Audio">label:Audio</a><br>
<br>
<br>
<big>And then:<br>
<br>
xxx.xxx.xxx.xxx (FS public ip) port 17094 -> 172.16.2.3 port
31200 codec: 8 ms: 30<br>
<br>
<br>
I tried with:<br>
<param name="NDLB-force-rport" value="true"/><br>
<param name="aggressive-nat-detection" value="true"/><br>
<br>
<br>
on internal profile and on trunk profile but the same.<br>
<br>
<br>
tnx for help!<br>
