[SR-Users] Problems establishing SIP signaling between MsTeams and Kamailio

Hello Rob and Kamailio Community,

I tell you to load the .pem certificate you attached as ca_list (in the
tls.cfg file) Finally, my file was like this.

[server:default]
method = TLSv1.2+
verify_certificate = yes
require_certificate = yes
private_key = /etc/letsencrypt/live/sbc.netvoiceperu.com/key.pem
certificate = /etc/letsencrypt/live/sbc.netvoiceperu.com/fullchain.pem
ca_list = /etc/letsencrypt/live/sbc.netvoiceperu.com/bc2025.pem
server_name = sbc.netvoiceperu.com

[client:default]
method = TLSv1.2+
verify_certificate = yes
require_certificate = yes
private_key = /etc/letsencrypt/live/sbc.netvoiceperu.com/key.pem
certificate = /etc/letsencrypt/live/sbc.netvoiceperu.com/fullchain.pem
ca_list = /etc/letsencrypt/live/sbc.netvoiceperu.com/bc2025.pem

After doing this I no longer got any error. Next I show the logs.

Also, I attach TLS communication flow between Microsoft and Kamailio (See
attached image "Flow TLS Certificate"). As you can see, the TLS
communication of the certificates is successful, however the SIP connection
to Microsoft is still status down.

[root at kamailio-server ~]# kamcmd dispatcher.list | egrep "URI|FLAGS"
                                        URI: sip:sip.pstnhub.microsoft.com
;transport=tls
                                        FLAGS: IP
                                        URI: sip:sip2.pstnhub.microsoft.com
;transport=tls
                                        FLAGS: IP
                                        URI: sip:sip3.pstnhub.microsoft.com
;transport=tls
                                        FLAGS: IP

Is it possible that I have an error or I am missing a configuration
parameter in the kamailio.cfg and dispatcher.list file?. Attached
kamailio.cfg and dispatcher.list

Please your great help to solve this.
