Then, in response to the display of the group number, the group number (01) is entered from the keypad within the operation keys 14a, and the group number is output to the exchange control section 2. Then, when the exchange control unit 2 determines to supply the group number, it connects the extension telephone terminals 10B, . The call is answered. In response to this response, the exchange control section 2 uses the group specification pickup control section 3 to subtract the count value for the group number "1" in the incoming call information storage table 4 to "0".

As described above, when responding to an incoming call to another group, a group-designated pickup request signal is output to the exchange in response to input of the group-designated pickup key from the extension telephone terminal of the other group. In response to this request signal, the exchange determines the group number of the incoming call based on the stored contents of the incoming call information storage table, and returns the group number as a result of this determination to the extension telephone terminal to which the request signal was supplied. The group number is displayed on the display inside the extension telephone terminal. Thereby, when receiving the group designated pickup service, the user can reliably answer an incoming call to another group by inputting the group number displayed on the display section. Therefore, the burden on the user when receiving the group designated pick-up service can be reduced, the functions of the service can be fully utilized, and the practicality can be increased.
