Hi Daniel, Thanks for your help with this. Here is a trace: http://pastebin.com/pXeFbwBz
I see the nat=yes parameter added to the Route header.
I've posted the script here: http://pastebin.com/2qwHYHvj
Forgive my ignorance, I can't tell what I'm doing wrong.
Thanks! Spencer

Hello,
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.
So, if you have a custom config, check the default one for the nat traversal handling part.
Cheers, Daniel

Hello, 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:
NATed UAC -> Kamailio on a public IP -> UAS on a public IP
Thanks in advance, Spencer
