Hello Fred and all,

I tried some changes, and result bellow.

with :

[server:default]
method = SSLv23
verify_certificate = no
require_certificate = no
private_key = /etc/certs/webrtc.killermobile.mobi/key.pem
certificate = /etc/certs/webrtc.killermobile.mobi/cert.pem
ca_list = /etc/certs/demoCA/cert.pem

[client:default]
verify_certificate = yes
require_certificate = yes
~                           

error log:

and tried:

[server:default]
method = SSLv23
verify_certificate = yes
require_certificate = yes
private_key = /etc/certs/webrtc.killermobile.mobi/key.pem
certificate = /etc/certs/webrtc.killermobile.mobi/cert.pem
ca_list = /etc/certs/demoCA/cert.pem

[client:default]
verify_certificate = no
require_certificate = no

and error log:

Then, i try with TLSv1+


[server:default]
method = TLSv1+
verify_certificate = yes
require_certificate = yes
private_key = /etc/certs/webrtc.killermobile.mobi/key.pem
certificate = /etc/certs/webrtc.killermobile.mobi/cert.pem
ca_list = /etc/certs/demoCA/cert.pem

[client:default]
verify_certificate = no
require_certificate = no

and log is:

Jul 15 03:08:33 ip-172-31-44-170 sbin/kamailio[17826]: ERROR: tls [tls_server.c:1283]: tls_h_read_f(): protocol level error
