DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of an extension call system for each caller of a private branch exchange according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a private branch exchange (PBX) that mediates various functions of outgoing / incoming calls, and through extension telephone interface circuit 2, extension telephones 8, 9, 10 and extension telephones 11, 12, 13 which are members of the hunting group 23 and extension telephones 14, 15 which do not belong to any group are connected. A telephone station 7 is connected via the station interface circuit 4, and external telephones 16 and 17 are connected via the telephone station 7.
[0012]
The telephone numbers of the extension telephones 8 to 15 and the external telephones 16 and 17 can be registered in the hunting group management table 18 as destination telephone numbers corresponding to the extension lines and the external lines, respectively. Registered in the hunting group management table 18 are a hunting incoming call number management table 19, a destination hunting group management table 20, a hunting incoming call ringing tone setting management table 21, and the like.
[0013]
The communication path switch 3 is a switch for controlling the communication path between the extension telephone and the external telephone that make and receive calls. The central processing unit 5 selects the destination based on the information in the hunting group management table 18 in the memory area 6. It is something to control.
[0014]
Next, the operation of this embodiment will be described. First, the extension telephone 14 or the extension telephone 15 outside the hunting group, or the outside telephone 16 or the outside telephone 17 calls the hunting group 22 or hunting group 23 accommodated in the PBX 1 using the pilot number. Then, the central processing unit 5 searches the hunting group incoming number management table 19 in the hunting group management table 18 in the memory area 6. When there is an extension number of a hunting group member that matches the caller's telephone number, the extension telephone number in the hunting group is taken out and called as the first destination of the hunting group call. For example, when the extension telephone 14 of the extension number 201 places a call, the extension number telephone number of the hunting group member that matches this telephone number exists in the hunting group incoming number management table 19, so the hunting group incoming number management table 19 The extension number 101 is taken out of the telephone number and called as the first destination of incoming hunting groups. If the caller telephone number does not exist, normal hunting is received.
[0015]
Further, in the hunting group management table 18, the hunting destination group number corresponding to the caller's extension telephone number can be called, and the calling party number and the corresponding destination hunting group are connected to the destination hunting group. By setting in the group management table 20, it is possible to make an incoming call first to the destination hunting group corresponding to the caller. For example, when the caller calls the extension telephone 8 with the extension number 101, the hunting group management table 20 has a destination hunting group member that matches the telephone number. The group 22 is taken out and the hunting group 22 is first called.
[0016]
The hunting group management table 18 further includes a hunting incoming call ringing tone setting management table 21 for setting a busy ringing tone only for a certain calling source number for each extension telephone in the hunting group. Thus, even when a hunting call is made, the corresponding destination can set a busy ringing tone. That is, the hunting incoming call ringing tone setting management table 21 in which the function of enabling / disabling the busy ringing tone to the calling party number and the corresponding destination extension number is set in the hunting group management table 18. By providing, a busy ringing tone can be sounded to the destination extension being used. For example, if a busy ringing tone can be set for the called extension 101 corresponding to the calling number 201, the calling number 210 is called even if the called extension 101 is busy. In this case, the destination extension 101 can ring a busy ring tone.
[0017]
【The invention's effect】
As described above, according to the extension call system for each caller according to the present invention, in the hunting group, which is a service function for setting an incoming call for each caller in the private branch exchange, the destinations for each caller number are assigned to the hunting group. By setting in the management table, the first destination can be changed at any time by the caller, and the other party who wants to receive the call can be called earlier. Furthermore, even if the destination cannot respond, using a hunting group allows you to make calls to someone in the group, not just a single phone, making it easier to contact by phone, making it easier to use A private branch exchange system that can provide a good telephone service can be realized.
