Abstract

According to the present invention, when an extension subscriber locks a phone using a secret code inputted by a program in a key phone system, the locked phone cannot control all calls other than a phone number starting with an emergency call code entered into the system. The essential phone is a lock code method in a key phone system that allows a call while restricting unnecessary calls.
