Hi!
1. start openser on both servers
2. make sure openser is running (both servers)
# ps -Alf|grep openser
3. make sure openser is listening on port 5061 (both servers)
# netstat -anp|grep 5061
4. configure the opensers to call each other via TLS
e.g. configure 2 SIP clients. One registers at proxy A while the other
registers at proxy B. Lets assume the Client A uses username a
(sip:[EMAIL PROTECTED]) and client B uses username b
(sip:[EMAIL PROTECTED]).
Now configure proxy A to route calls to B via TLS.
if (uri =~ "b@") {
# write new destination into an AVP
avp_printf("$avp(s:new_uri)","sip:[EMAIL PROTECTED];transport=tls")
# push new uri into reuqest URI
avp_pushto("$ru","$avp(s:new_uri)");
t_relay();
}
5. call from a to b
6. use ssldump to watch TLS call setups
regards

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.
