Hello, the errors can be because of various reasons such as: - requiring a tls method not supported (tlsv1, ...) - not having a common cypher - requiring certificate, but the other party not providing one - requiring a valid certificate, but the validation fails Try to run with debug=3 and see if you can spot further hints from the debug messages.

I don't know where I should search for the cause of these errors and how to debug and remove them. I don't know if these errors are caused by incorrect kamailio configuration or are caused on client's side.
