Dear Kamilio Community,
After doing several reads to our Kamailio configuration, the dispatcher
list is in AP:
URI: sip: sip.pstnhub.microsoft.com; transport = tls
FLAGS: AP
URI: sip: sip2.pstnhub.microsoft.com; transport = tls
FLAGS: AP
URI: sip: sip3.pstnhub.microsoft.com; transport = tls
FLAGS: AP
But in the MS Teams dashboard the SIP OPTIONS STATUS column is WARNING.
In the LOGs sent to OPTIONS, it gives us to understand that with sent to MS
TEAMS:

Jan 8 19:01:42 Kamailio-Server journal: Suppressed 103 messages from
/system.slice/kamailio.service
In the kamailio.cfg configuration it is declared:
listen=tls:161.35.44.66:5061
listen=tcp:10.131.245.99:5061
modparam ("dispatcher", "list_file",
"/etc/kamailio/dispatcher.list")
modparam ("dispatcher", "ds_probing_mode", 1)
modparam ("dispatcher", "ds_ping_interval", 60)
And this fragment was also added:
event_route [tm: local-request] {
if (is_method ("OPTIONS") && $ ru = ~
"pstnhub.microsoft.com") {
append_hf ("Contact: <sip: sbc.netvoiceperu.com: 5061;
transport = tls> \ r \ n");
}
xlog ("L_INFO", "Sent out tm request: $ mb \ n");
}
There is something additional that has to be declared so that in the MS
Teams panel the SIP OPTIONS STATUS column is shown as ACTIVE and not as
WARNNING, in the MS TEAMS documentation it is a possible problem related to
OPTIONS events.

Does this happen when Kamailio connects to MS Teams?
The logs indicate the
received TLS certificate is not trusted:
Jan 6 15:13:55 Kamailio-Server /usr/sbin/kamailio[32425]: ERROR: tls
[tls_util.h:42]: tls_err_ret(): TLS write:error:14090086:SSL
routines:ssl3_get_server_certificate:certificate verify failed
You can set debug=3 in kamailio.cfg and see if the DEBUG messages provide
more hints. For me it worked fine with Letsencrypt certs in Kamailio and
accepting what ever MS sent back. I used Debian 10 and libssl 1.1.
Cheers,
Daniel

Hello community,
I am having trouble establishing SIP signaling between MsTeams and
Kamailio. I currently have this configuration in my tls.cfg file
[server: default]

My domain was certified with ssl through an authoritative certifier
(GoDaddy), however I see these errors in the / var / log / messages of the
Kamailio server.
