PROBLEM TO BE SOLVED: To improve convenience by eliminating the need for waiting for the response of a party by setting the refusal of call incoming during call incoming corresponding to the operation of a certain extension terminal at call incoming to this extension and reporting the setting of call incoming refusal to the side of call origination. SOLUTION: When a call is received at an extension A, and the response to a terminated call is disabled and there is no person around available for responding to the call even around an extension or the like in the same group, 'hold key + present extension number' is dialed, while keeping an on-hook state. When 'hold key + present extension number' is received from the extension A, a private automatic branch exchange 201 decided it as a call incoming refusal setting request during call incoming from the extension A, registers the extension number, caller number, set function and Day/Time at the time of function setting into a call incoming setting table managed by a call incoming setting table part 220 of an extension interface part 216 and performs call incoming refusal setting processing with respect to the extension A. At a time when call incoming refusal is set, a ring back tone is stopped for the extension A.
