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@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.

Atentamente

Adalberto Carlos Mestanza T.

That certificate should already be present under the OS's trusted
certificates directory (debian and ubuntu certs are stored under
/etc/ssl/certs), maybe under a different name, and is required for
remote endpoint's certificate validation.
One can load a particular certificate or a list of certificates.
Multiple certificates can be concatenated into one single file as
stated in the documentation:
https://kamailio.org/docs/modules/devel/modules/tls.html#tls.p.ca_list
Hope this helps a little bit in understanding of the ca_list param.
