Dear Klaus,

Thank you very much for your help and reply my message. Thank you very much.

I am very happy to read the reply from you.

Klaus, maybe I am too stupid, may I ask you question anymore? Please...

may I ask you about TLS again?

Because I am not sure that the configuration that I have made before, is good. Can I ask you?

1. Here is :

In my openser.cfg, for support TLS, I just uncomment the TLS support (the certificate). Here is the part of my openser.cfg :

# uncomment the following lines for TLS support
disable_tls = 0
listen = tls:202.95.149.251:5061
tls_verify_client = on
tls_require_client_certificate = on
tls_verify_server=on
tls_method = TLSv1
tls_certificate = "/usr/local/etc/openser/tls/user/user-cert.pem"
tls_private_may I ask you about TLS again?

Is this way correct? or there is another configuration that I must make or I have added in openser.cfg, in order the TLS can run successfully?

2 . You said that I can test it by using 2 openser server. I have built it. One using Fedora core 4 and the othe using Redhat 9. But I am confused, how to connect this two openser server? What I have added in openser.cfg in order both of the server can be used to communicate and test TLS ? Would you mind tell me Klaus?

Please give me a suggestion..Please

Thank you very much,

Thank you

Regards,

Ferianto

xlite supports TLS, also minisip

you can also use 2 openser's to talk TLS between the 2 openser's

yes. but make sure the connection is really routed via port 5061/TLS.

Good tools for debugging:

1. ssldump
2. ngrep (check the ports which are used)
3. you can configure openser TLS to use NULL cipher. This way it is TLS
but not encrypted and you can use a packet sniffer to watch the signaling.
