The "-C" option, since we're defining a client this time, is used to define the hostname or IP address of our SIP phone.

The "-k /etc/asterisk/keys/ca.key" provides the key for the above-defined Certificate Authority.

The "-c /etc/asterisk/keys/ca.crt" option specifies which Certificate Authority (ourselves) that we're using.

The "-m client" option tells the script that we want a client certificate, not a server certificate.
