PROBLEM TO BE SOLVED: To enable a telephone number of a centralized management device set to a management device to be automatically changed without stopping system operation by storing a telephone number stored in a second storage area in a first storage area when communication, based on the telephone number stored in the second storage area is successful. SOLUTION: A storage device 22 of a management device 20 is provided with two areas E1 and E2 for storing a telephone number of a centralized management device 60. The area E1 (a first storage area) stores a telephone number D1 of the centralized management device 60. The area E2 (a second storage area) stores a telephone number D2 beforehand after a change when the telephone number of the centralized management device 60 is changed. Thus, by setting the telephone number D2 after the change in advance in the area E2, the call origin telephone number D1 set in the management device 20 is automatically changed after the telephone number of the centralized management device 60 is changed.
