Hello,
set debug=3 in kamailio.cfg, restart kamailio and try to connect again with the client. Watch the logs and you should get more details about what happens there.
Cheers,
Daniel
Hello everyone,
I am trying to configure TLS in kamailio (5.2.4) following this guide: http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates
Modules:
#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB
#!define WITH_PRESENCE
#!define WITH_ALIASDB
#!define WITH_IMC
#!define WITH_TLS
When i try to connect via command line, this is the result (just including relevant parts):
$ openssl s_client -connect 192.X.X.X:5061 -tls1
CONNECTED(00000003)
depth=1 C = XX, ST = XXXX, L = XXXXXX, O = XXX CA, CN = XXX CA
verify error:num=19:self signed certificate in certificate chain
verify return:0
---
No client certificate CA names sent
---
SSL handshake has read 2550 bytes and written 336 bytes
---
---
Start Time: 1567787935
Timeout : 7200 (sec)
Verify return code: 19 (self signed certificate in certificate chain)
---
read:errno=0
Now, when I setup my clients, they connect to the server, but they can't send messages or make calls.
This is the TLS startup LOG:
