After some more research I found:<br>
<a href="https://community.asterisk.org/t/box-with-2-interfaces-wrong-one-chosen-in-contact-header/74705/3" rel="noreferrer" target="_blank">https://community.asterisk.org/t/box-with-2-interfaces-wrong-one-chosen-in-contact-header/74705/3</a><br>
<br>
And some more similar ones describing the same problem with chan_sip<br>
and pjsip.<br>
<br>
I attempted to set: external_signaling_address on my transports. Also<br>
trying to trick them there could be NAT (there is none) by setting.<br>
local_net=<a href="http://192.168.99.0/24" rel="noreferrer" target="_blank">192.168.99.0/24</a><br>
<br>
Asterisk is still sending the wrong IP Address in the Contact header of<br>
183 or 200 messages.<br>
<br>
Can anyone confirm this is a bug?<br></blockquote><div><br></div><div>There's been a lot of work in this area since 13.18. Without seeing packet captures of the incoming request and the response and seeing the exact configuration of the endpoints and transports it's hard to say what's going on. One thing you can try is setting "symmetric_transport=yes" on the two transports. That should ensure that the responses go out the same transport as the one that received the request. That, in turn, should change the contact address accordingly.</div><div><br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
