Specifically, the first call control unit 22 permits transmission of the representative incoming call information by the information transmitting unit 24, and when there is a representative incoming call, the first call control unit 22 selects the extension fixed terminal 70 belonging to the group of the destination of the representative incoming call. call only. The electronic terminal 60 belonging to the destination group is not called.

The second call control unit 25 prohibits the transmission of the representative incoming call information by the information transmitting unit 24, and if there is a representative incoming call, all extension terminals belonging to the group of the destination of the representative incoming call (that is, all extension Call the fixed terminal 70 and the electronic terminal 60).

The call control switching unit 26 determines whether to execute call control by the first call control unit 22 or the second call control unit 25 when there is a representative incoming call. Or switch according to the current time.

For example, the call control switching unit 26 executes call control by the first call control unit 22 when the number of belonging electronic terminals 60 belonging to the destination group is equal to or greater than a predetermined threshold, and the belonging electronic terminals 60 is less than the threshold, the call control by the second call control unit 25 is executed. The threshold is set to the minimum number of electronic terminals 60 that may be judged as a cyberattack by an external system when they are called simultaneously. As a result, when there is no possibility that the external system will judge a cyberattack even if simultaneous calls are made, the electronic terminal 60 can smoothly respond to the representative incoming call by calling all the extension terminals.

Further, for example, the call control switching unit 26 executes call control by the first call control unit 22 when the current time is in a preset first time zone, and also executes call control by the first call control unit 22 when the current time is a preset second time period. If it is band, call control is executed by the second call control unit 25 . This makes it possible to improve the convenience of responding to a representative incoming call by performing call control suitable for the time slot.
