PURPOSE:To limit the incoming call in excess of a reply enable number in this group by applying the incoming limit processing of an incoming call when the number of busy subscribers in an incoming limit group belonging to a subscriber exceeds the maximum incoming enable number. CONSTITUTION:When a subscriber A hooks off, a ring tone from an ORT 2 via a SW 1 is listened to and then the extension number of a subscriber B is dialed, a CPU 5 reads group G1 information belonging to the subscriber B from an MA 6, and then the maximum incoming allowable number '1' of the group G1 read from an MB 7 and the number of busy subscribers '1' of the group G1 read from an MC 8 are compared. Since the relation of busy subscriber number >= maximum incoming allowable number exists, the CPU 5 applies busy processing. If the relation of bush subscriber number < maximum allowable incoming number exists at the comparison of the CPU 5, the CPU 5 applies the call processing of the subscriber B, a call signal is sent to the subscriber B and call tone is sent to the subscriber A.
