PROBLEM TO BE SOLVED: To provide a communication device capable of specifying a caller terminal by a discrimination code inputted after closing of a line even in the case of non-insertion of a Caller ID to a call signal and capable of closing a line in the case that the caller terminal is the terminal preliminarily registered in a storage means. SOLUTION: It is discriminated whether the Caller ID is inputted together with the call signal or not (S2), and a CPU controls an NCU to close the line (S9) if the Caller ID is not inputted (S2: NO). That is, the caller terminal can be specified by the discrimination code inputted after closing of the line even if the Caller ID is not inputted. |
