Hi, could you please help me check this issue? Or provide tutorial links for WebSocket installation and configuration. Requirement: Support WebSocket signaling Configuration in Kamailio.cfg as follows: [Please paste your specific configuration here]
3. I keep getting the following syntax error in my Kamailio configuration:
4. We suspect it might be because WebSocket is not supported during compilation and installation.
5. Additional information: The websocket.so file exists in /usr/local/lib64/kamailio/modules/, along with other dependencies like xhttp, etc.
Best regards, Kamailio User
Hi!
I don’t think ws: is an available prefix for the listen= directive. Please check with the core cookbook for the version you are using. Here's a link for v6.0 (Yes, I think it could be improved with a better list of available protocols).

You do mention the websocket module. I suggest you take a look at the websocket module documentation: https://kamailio.org/docs/modules/6.0.x/modules/websocket.html%EF%BF%BC There are some code examples in there to start with. This should get you going.

Hi
ws will use tcp and wss will use tls
see the example in the websocket module documentation
so your ws listen should be listen=tcp:192.168.6.22:5066

The syntax for that is actually tcp, not ws. The ws upgrade happens after the client connects, check https://github.com/davidcsi/voip-full-k8s-sip-proxy/blob/master/kamailio.cfg

WS uses tls as its transport ans wss uses tls for its transport.
Therefore you need listen=tcp:192.168.6.17:5066 and also the module compiled and loaded

Hello,
just for the archives, WS uses TCP and WSS uses TLS in the Kamailio context.
Cheers,
Henning
