<p>Hello,</p>
<p>it seems that the ACK comes in, but my guess is that the R-URI is
not properly set. From the logs it looks like same value as for To
header URI, while it should be the address in Contact header of
200ok for INVITE.</p>
<p>Load the sipdump module and that will save all the sip traffic in
a text file, making it easier to see what comes/goes on both
directions, no matter is over tls or not. If you use kamailio
devel version (master branch), then sipdump module can also store
traffic in pcap file (tls traffic saved as udp for simplicity, but
it is easy to spot from headers or meta data extra header).</p>
<p>You can send the sipdump file here for investigation, so we can
see if some headers or r-uri are not correct.</p>
<p>Cheers,<br>
Daniel<br>

<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>
