now that 3.1 has async tls support, i decided (first time ever) to try
to test tls. things went quite smoothly when i followed "Create
Certificates to be used with Kamailio" document
http://kamailio.org/dokuwiki/doku.php/tls:create-certificates#using_the_cer…
during the process, i fixed a typo in the doc, added two comments to cfg
part:
enable_tls=1
tcp_async=no # do not include in 3.1
listen=udp:0.0.0.0:5060
listen=tcp:0.0.0.0:5060
listen=tls:0.0.0.0:5061 # not needed in 3.1
and fixed wrong file references in client configurations:
eyebeam: copy the CA certificate (/etc/certs/demoCA/cert.pem) to the Windows PC and add it
to the Windows certificate store (Start→Control Panel→Internet)
QjSimple: copy the CA certificate (/etc/certs/demoCA/cert.pem) to the
client PC and configure QjSimple to use this CA (“TLS CA file” and
“verify TLS server certificate)
earlier the paths pointed to certs/sip.mydomain.com files, which i think
were wrong. at least i was not able to get them working.
perhaps someone who is more familiar with tsl stuff could verify the
above changes.

I added note about configuring Snom phones to connect over TLS and
created a section from that part:
http://kamailio.org/dokuwiki/doku.php/tls:create-certificates#using_tls_and…
Also, in my configs I set:
tcp_connection_lifetime=3610
Which is slightly higher than max allowed registration time. Some
clients do not reconnect if tcp/tls connection is closed by server.
Maybe we should add this one in the wiki as well.
Cheers,
Daniel

one question about the certificate tutorial: is something else needed in
the config or certificate business, when sr talks over tls with another
sip proxy, e.g. another sr? namely in that case sr may be in client
role when tls session is established.

Nothing special if needed.
However if you want to have different certificates in function of the
role, or who are you talking with, you need to use a separate tls config
file

ok thanks. i added a note about that to the tuto.
one more thing i would like to add to the tuto if someone knows the
answer: how to capture/see sip over ssl packets in the proxy host using
wireshark, ngrep, or something?

i was able to figure out how do to it using wireshark. one needs to go
to Preferences/Protocols/SSL and there add to RSA keys list:
<ip-of-sip-proxy>,5061,sip,/etc/certs/sip.mydomain.com/key.pem
then in Options specify 'port 5061'. after that, new ssl connections
will be shown in clear.
i don't know why ssldump didn't work with the same key.pem file.

For me it doesn't work with -i any, but works with -i eth0.
To quickly create a test tls connection I use:
openssl s_client -connect host:5061 -tls1

You are right.
Thanks for fixing my bugs :-)

If you use 0.0.0.0 you _must_ set adevertised_adress or
you will have some strange Vias && RRs.

listen which does not specify the protocol
(e.g. listen=10.0.0.2:5060 or

listen on all protocols on the default
port). I
This is true also for 3.0 and at least for
all ser versions.
In general I use

as a quick setup reminder.

I wonder which IP address is used as TLS socket if you do not specify it
in the config file?
I always specify it explicitly as I do not want any kind of automatism.
