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.
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).
You can send the sipdump file here for investigation, so we can see if some headers or r-uri are not correct.

So, I understand that ACK comes from Teams, right? So kamailio routing problem?
Thanks

Hello,
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...
Cheers,
Daniel

if(is_method("OPTIONS") && $ru =~ "pstnhub.microsoft.com") {
append_hf("Contact: <sip:FQND:5061;transport=tls>\r\n");

$rU="1005";
}}
What I'm doing wrong?
I don't understand why not received ACK..
Could anyone help me?
