It

FIG. 2 shows a memory configuration of the outside line reservation memory unit 61 of the key telephone device according to the embodiment of the present invention. In the present embodiment, a maximum of N button telephones can simultaneously make an outside line reservation for one outside line, and one destination telephone number can be registered for each button telephone. Here, N is the number m or less of the key telephone in FIG. Therefore, the memory is composed of N button telephone number registration units and destination telephone number registration units for each number of outside lines.

Next, the operation of the embodiment of the present invention will be described with reference to FIGS. When the key telephone 11 performs a capturing operation for the outside line trunk 31 in use,
The key telephone 11 listens to the busy tone. At this time, if the destination telephone number is entered at the same time when the outside line reservation operation is carried out, the control unit 5 calls the reserved key telephone 11 in the memory (All and Bll in FIG. 2) corresponding to the outside line trunk 31 in the outside line reservation memory unit 61. Register the entered destination telephone number.

Next, when the outside line trunk 31 becomes empty, the control unit searches the outside line reservation memory unit 61 and the outside line 1
The registered key telephone number and destination telephone number are read from the memory (All and Bll in FIG. 2).

As a result, when the button telephone 11 is called as the reserved telephone and the button telephone 11 lifts the handset, the outside line trunk 31 captures the outside line and the voice communication path between the outside line trunk 31 and the button telephone 11 is switched by the switch circuit 4.
