Hello,
the command to rtpproxy for the reply seem to miss the to-tag, can you grab the ngrep
trace for such call and the logs for processing it? Having the logs from a different call
than the ngrep trace you posted on pastebin is not helping much.
Cheers,
Daniel

incorrect port 0 in reply from rtp proxy
I was able to get it working correctly by reworking the config like the 3.1 branch by
using rtpproxy_offer instead of force_rtp_proxy. When I attempted to use rtpproxy_answer
in the reply route, I was getting the same lookup request failed error from rtpproxy. In
the request and reply, the tags change. Could this be the reason that the session lookup
is failing? If I use rtpproxy_offer in both the request and reply, everything works
correctly. Is there any consequence to doing this?
Thanks,
Spencer

I've included a debug level log from rtpproxy in the log as well.

best is to use the debugger module with cfg_trace parameter set and check the execution

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 Connected by DROID on
