When a caller telephone number corresponding to the received password is dissident with the received contact source telephone number (NO) after the end of communication, the received password and the contact source telephone number are sent to the equipment of the caller telephone number and a message is sent thereto. When they are coincident (YES), the password and the contact end notice signal are sent to the equipment of the caller telephone number.
