When the operation of an outside line button not shown is detected, this operation information is transmitted to the main device 1. In this case, the CPU 14 of the main device 1
When the external line button operation information is received via the telephone interface, the corresponding external line interface is controlled and the external line is captured.

Thereafter, when the auto key A of the keyboard 57 of the key telephone 5 is operated and the operation information is transmitted to the main unit 1, the CPU 14 of the main unit 1
The M16 reads out the auto-dial number registered in the area of the key telephone set and sends it to the corresponding external line interface to transmit the corresponding dial signal to the external line that has captured the dial signal. Calling of the other party is performed by sending the dial signal to the captured outside line, and the other party responds to the outside line communication state.

[0012] Figure 3 is a diagram showing a storage status of the auto dial number in RAM 16, the key telephone (i.e., handset) dial memory DM1~DMm every 5 ₁ to 5 _m are prepared. In FIG. 3, the number of key telephones is three.
While dial memory DM1~DM3 to each key telephone set 5 ₁ to 5 every ₃ shows an example provided in the case of the number of key telephone is also turned to m. A plurality of dial numbers can be registered in each of the dial memories DM1 to DMm. That is, the auto key A of each key telephone is composed of a plurality of auto dial buttons as described above, although not shown, and when the auto dial button A ₁ is operated while capturing an outside line, for example, the operation data The CPU 14 of the main device 1
