<p>Hello,</p>
<p>run with debug=3 in kamailio.cfg and see if the ACK comes to
Kamailio, if yes, then some routing issue in kamailio.cfg. If does
not come, you will have to check the headers to see if MS Teams
expects something else there, typically is about Record-Route
domains...</p>
<p>Cheers,<br>
