Dear,

I am trying to make a test to see how can webrtc work in kamailio and tls.

I was try some link :
1. https://github.com/havfo/WEBRTC-to-SIP
2. https://telecom.altanai.com/2018/09/04/kamailio-webrtc-sip-server/

And Generate CA from the link:

https://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates

Then, I tried to login with simpl5 and i got the message back 
Disconnected: Failed to connet to the server

I do not know how can i fix that issue, look like TLS configure has issue with that. the log is showing something like

Jul 14 17:56:16 ip-172-31-44-170 sbin/kamailio[13813]: ERROR: tls [tls_server.c:1283]: tls_h_read_f(): protocol level error

My tls.cfg is :

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

[client:default]
verify_certificate = yes
require_certificate = yes

Please help me to register sipml5 or how can i create CA for TLS in kamailio to use with webrtc.

Thank all.
