Hello,

I can suggest that you run with debug=3 in kamailio.cfg and watch the logs printed by kamailio in syslog to see what happens.

If you need to look at the traffic sent over the tls connection, load sipdump module and enable it to write traffic in a file.

Cheers,
Daniel

OK, spent some time around tls configuration. OpenSSL shows no error now, but dispatcher continues to show me IP or AX.

openssl s_client -showcerts -debug -connect servername.com:5061 -no_ssl2 -bugs -servername  servername.com -CAfile /root/intermediate.crt

Teams web-interface shows inactive. Kamcmd's same as previous output. What do I do :(?

Hello.

I'm trying to set up Kamailio as SBC for Teams using https://skalatan.de/en/blog/kamailio-sbc-teams.

Setup is completely default (except things mentioned at article), but I use wildcard certificate for TLS. Well, I can't even pass dispatcher:

kamcmd dispatcher.list | egrep "RI|FLAG"
                                        URI: sip:sip.pstnhub.microsoft.com;transport=tls
                                        FLAGS: IP
                                        PRIORITY: 3
                                        URI: sip:sip2.pstnhub.microsoft.com;transport=tls
                                        FLAGS: IP
                                        PRIORITY: 2
                                        URI: sip:sip3.pstnhub.microsoft.com;transport=tls
                                        FLAGS: IP
                                        PRIORITY: 1

Where do I start to dig?
