〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the incoming call display method according to the present invention. In Figure 1, 1 to 3 are telephones, 4 is a switch, 5 is a central office trunk,
6 is a dedicated line, 7 is a central control unit, and 8 is a storage device.

The storage device 8 is provided with a storage area for storing incoming call control information and display information of extension subscribers, and stores incoming call control information and display information specific to each extension subscriber as necessary.

FIG. 2 shows incoming call control information and display information stored in a storage area provided in the storage device f8.
