Hello,<br>
<br>
if your config it is based on the default one, the Route header for
within dialog requests is marked by a parameter, nat=yes, that is
used to decide whether to do rtpproxy or not.<br>
<br>
So, if you have a custom config, check the default one for the nat
traversal handling part.<br>
<br>
Cheers,<br>

<div style="font-family: sans-serif; font-size: 16px">Hello,<br>
I'm using Kamailio 3.2.4 for NAT traversal using
rtpproxy_manage() in a largely stock script. Everything works
great until the far end (on a public ip) sends a t.38
re-INVITE. The 200OK from the NATed UAC then doesn't trigger
rtpproxy and the private IP in the sdp causes the fax to fail.
Any help handling these re-INVITEs would be greatly
appreciated. I'm happy to post traces if that helps describe
the situation. The network topology looks like this:<br>
<br>
NATed UAC -> Kamailio on a public IP -> UAS on a public
IP <br>
<br>
<br>
Thanks in advance,<br>
Spencer<br>
