Moreover, about the operation | movement of the server 4 provided in the call center of an emergency call provider, the same process number (ST21-27) as FIG. 5 is attached | subjected, and description is abbreviate | omitted. Hereinafter, the operations of the exchange and the telephone transfer device constituting the telephone line network 6 will be mainly described.
In addition, the telephone transfer device has received an initialization signal from the server 4 in advance, and receives incoming voice calls from all telephone numbers to the PBX 2 with respect to the telephone line network 6 by any terminal other than the PBX 2 or Assume that you have set up forwarding to the switch.

  First, in step ST31, when the telephone transfer apparatus receives an incoming call permission signal including the telephone number of the emergency call apparatus 1 that has transmitted the identification number from the server 4, the telephone transfer apparatus registers the telephone number and is assigned the telephone number. The exchange constituting the telephone line network 6 is set so that the voice call from the reporting device 1 to the PBX 2 is not transferred and is received as it is.

  Next, in step ST32, when the emergency call apparatus 1 that has transmitted the identification number makes a voice call, the exchange constituting the telephone line network 6 connects the telephone line between the emergency call apparatus 1 and the PBX 2.

  Next, in step ST33, the exchange constituting the telephone line network 6 disconnects the telephone line between the emergency call device 1 and the PBX 2 when the call end button of the emergency call device 1 or the operator telephone 3 is pressed. . Although FIG. 6 shows an example in which the call end button of the emergency call device 1 is pressed, the telephone line is similarly disconnected when the call end button of the operator telephone 3 is pressed.

  Next, in step ST34, when receiving the incoming call rejection signal including the telephone number of the emergency call apparatus 1 that has transmitted the identification number from the server 4, the telephone transfer apparatus cancels the registration of the telephone number and transfers the telephone number to the PBX 2. The exchange configuring the telephone line network 6 is set again so that the voice call is transferred to an arbitrary terminal or exchange different from the PBX 2.

  As described above, the exchange and the telephone transfer device constituting the telephone line network 6 receive the incoming call permission signal and the incoming call rejection signal from the server 4, and call the emergency call device 1 to the PBX 2 with PBX 2. Switch between forwarding to another terminal or switch or receiving the call as it is.
