Hi,

Im trying to connect my WebRTC clietn to kamailio via WSS. I successfully connected it via WS but having trouble connecting it via WSS. My first issue is I get error messages while i try to compile TLS module(console log in the end of the document). But, still it creates tls.so file. So i copied the tls.so to my kamailio modules directory and then updated my kamailio configuration as below:

#!define WITH_TLS

.

.

listen=tcp:127.0.0.1:5061

listen=tcp:192.168.146.133:5061

.

.

#!ifdef WITH_TLS

enable_tls=yes

#!endif

.

.

#!ifdef WITH_TLS

# ----- tls params -----

modparam("tls", "config", "/usr/local/kamailio-devel/etc/kamailio/tls.cfg")

#!endif

Now, according to this mailing list,http://lists.sip-router.org/pipermail/sr-users/2013-March/077182.html : “when tls module is installed, a self signed pair of certificate-private key is generated in /usr/local/etc/kamailio”

In my case, I dont even have the /usr/local/etc/kamailio directory. So, I followed http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates to create my certificate and key. And updated my tsl.cfg, this is how my tsl.cfg looks like:

[server:192.168.146.133:5061]

method = TLSv1

verify_certificate = no

require_certificate = no

private_key = /etc/certs/sip.192.168.146.133/key.pem

certificate = /etc/certs/sip.192.168.146.133/cert.pem

ca_list = /etc/certs/demoCA/cert.pem

[client:192.168.146.133:5061]

verify_certificate = yes

require_certificate = yes

Then I restarted my kamailio server. And i get the following errors in my kamailio log:

Im not sure what wrong im doing. Please help me:
