That’s my experience, too, but perhaps there’s something not quite clear about the location of the tls.cfg file, or the applicability of the given profiles, etc.

Hello Alex,

if you set this in a dedicated tls.cfg, its in my experience not necessary to set these parameters additionally in the kamailio.cfg.

Hello,

We have a Kamailio 5.2.7 server with WebRTC enabled. However, a WebRTC client at https://tryit.jssip.net/ is unable to connect on either Chrome or Firefox. In the Kamailio log we see the lines below.

Hello,

In this case the server should not reject clients without certificate. So, the error needs to be something else, maybe you can see on the client side something with a network trace.

As a side note, you should consider updating to a supported Kamailio version, the 5.2.x is really old.

Cheers,

Henning

I grepped the log and we do see "Server MUST present valid certificate" but not "Client MUST present valid certificate".

Would anyone have any further pointers?

Thank you.
