Would anyone have any further pointers?

Thank you.

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.

In the Kamailio log we see the lines below. In tls.cfg we have "verify_certificate = no" and "require_certificate = no" for both [server:default] and [client:default]. Would anyone be able to help us with this?
