What does "port-forwarded from the WAN NIC" mean? How many interfaces are on the system, and what are they? Restarting Asterisk results in the same issue? Are you able to...

Unfortunately without being able to reproduce it fixing it or identifying the cause is next to impossible. Noone else has so far reported it, and I haven't been able to...

I understand it is Asterisk-generated INVITEs. Those are what I have been checking.

That also only executes a single time in my successful case. The tdata if I recall correctly gets reused, including the underlying SDP.

Yes, I was giving some thought to that and if somehow somewhere it did restore the local IP address then that would do it. I haven't yet found anywhere specifically.

Ok, that doesn't help explain how the private IP address was placed back in the INVITE request and why the behavior differs for me.

Asterisk isn't a proxy, each side is independent so the triggering side should have no bearing - and it doesn't on that aspect of outgoing SDP. Removal of such code...

I assume this is using bundled PJSIP, too?

It is possible I am incorrect depending on where things are inserted into the PJSIP stack and their execution layer. The comment and logic are very much from the beginning...

[449-last-tx.txt](https://github.com/asterisk/asterisk/files/13369577/449-last-tx.txt) Please try this patch and provide the output. It outputs the packet from the transaction layer, which is reused on the resend with authentication. If that is incorrect it...
