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:a@ip.address.of.proxyA) and client B uses username b
(sip:b@ip.address.of.proxyB).
Now configure proxy A to route calls to B via TLS.
if (uri =~ "b@") {
# write new destination into an AVP
avp_printf("$avp(s:new_uri)","sip:b@ip.address.of.proxyB;transport=tls")
# push new uri into reuqest URI
avp_pushto("$ru","$avp(s:new_uri)");
t_relay();
}
5. call from a to b
6. use ssldump to watch TLS call setups

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

Dear all,
Thank you very much for time to read my problem. Thank you very
much...
All, I have built openser server and I can build
it successfully. It
means that the client can make call each other.
The openser server that I build is support TLS (in openser.cfg, I
enable
the TLS support).
But, I need help for testing my TLS in voip communication.
I have type command : # openser -V , and I can see that the TLS
is used.
But,How can I test the openser that supported TLS? because in my
mind, for testing the TLS, I must have a software that supported
TLS.
xlite supports TLS, also minisip
you can also use 2 openser's to talk TLS between the 2 openser's
So, if the client can communicate each other by
using the
software phone
that supported TLS, it means that the TLS have
run successfully
(because
TLS use port 5061 ).
Is this opinion correct?
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.

Or can anybody give a suggestion how to test my openser TLS? if I
have
to use software phone that supported TLS.Please
tell me..Pelase..
Thank you very much for your help.
Thank you
