Thanks Daniel and Ding Ma. I have Certificate Authority, who signed the server certificate and client certificate. Server certificate and root CA is added to server. Client certificate and root CA is added to client. Now CRL file path is update with server and it's own server certificate is revoked. In this case what should be kamailio server behavior, if any client wants to establish TLS connection? or Since it's own server certificate is revoked TLS should be disabled on server side?
As per my understanding, TLS should be disabled on server side, as it does not have valid certificate. Please share your thoughts on this.
