DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to an alternative destination display method capable of improving a processing function in a reception desk of a private branch exchange and a telephone. (Prior Art) When an incoming call is internally connected via a reception desk of a private branch exchange or when an extension is transmitted from a telephone, the extension telephone dialed from the reception desk or the telephone is busy. Sometimes. In this case, the purpose of the call can often be achieved by transferring the incoming call to another extension telephone (alternate destination) near the extension telephone. However, conventionally, in order to know the telephone number of the alternative destination, it was necessary to rely on the memory of the exchange or the caller, or to search a telephone number table or a telephone number memo. However, when relying on the memory of the operator or the caller, accuracy is lacking, and it is troublesome to refer to the recorded material, which hinders an efficient exchange operation. (Problems to be Solved by the Invention) As described above, conventionally, it is difficult to accurately and promptly know an alternative destination, which is a major problem in facilitating the exchange operation. I have. The present invention has been made in view of such circumstances,
The purpose is not only when the destination is busy, but also when the destination does not respond within a predetermined time, the operator does not need to perform any setting operation and the alternative destination can be provided to the operator or the caller. It is an object of the present invention to provide an alternative destination display method capable of notifying a telephone number and facilitating the telephone / exchange operation. [Configuration of the Invention] (Means for Solving the Problems) In the present invention, an incoming call destination telephone number for an extension telephone to be handled by a reception desk or a telephone with a display is stored in a memory in advance, and the reception is performed. When an extension telephone is dialed from a stand or a display-equipped telephone, when the destination extension telephone is busy, and when it does not respond within a predetermined time, an alternative destination telephone number of the extension telephone is obtained from the above memory. For example, the telephone number is displayed in a predetermined alternative destination telephone number display area of the reception desk or the telephone with an indicator, or the display form of the telephone number corresponding to the alternative destination of the BLF of the reception desk is displayed in another manner. It is characterized in that it is displayed in such a way that it differs from the form. (Operation) According to the present invention, when an extension telephone is dialed from a reception desk or a telephone with a display, not only when the destination is busy but also when the destination does not respond within a predetermined time, The telephone number of the alternative destination for the extension telephone is obtained, for example, by selecting an empty telephone among the alternative destinations registered in the memory, and the telephone number is automatically presented to the operator or the caller. . Therefore, when the telephone at the dial destination is busy, for example, it is possible to quickly and accurately transfer the telephone to the telephone at the alternative destination. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of an exchange system configured by applying the method of the present invention. In FIG. 1, reference numeral 1 denotes a private branch exchange main body. A reception board (attendant; ATT) 3 is connected to the private branch exchange main body 1 via a reception board control circuit 2. 4 is the reception desk 3
And a display device such as a BLF. Reference numeral 5 denotes a central control unit called a CC, which controls a telephone exchange operation via the private branch exchange main unit 1. Reference numeral 6 denotes a memory for storing an exchange operation program and various control information. A plurality of extension telephones 8a, 8n are respectively connected to such a switch body 1 via subscriber circuits 7a, 7n, and extension telephones 10a, 10a,
To 10k are connected. A local line (external line) is connected to the private branch exchange body 1 through central line trunk circuits 9a to 9n. In the switching system configured as described above, the reception desk 3 normally responds to an incoming call from an outside line, and dials the called party's telephones 8 and 10 requested by the incoming telephone from the reception desk 3. The telephone connection is made. Extension calls are made by directly dialing the telephone number of the other party from the telephones 8 and 10 to make a telephone connection. However, in the present system, at the time of the above-mentioned telephone transfer, the reception table 3 executes, for example, the processing procedure shown in FIG.
That is, when dialing the extension telephone 8 that has received a call request from the reception desk 3, it is first determined whether or not the extension telephone _DNia is in a busy state (step a). If the result of this determination is that the extension telephone _DNia is busy,
Alternate destination telephone number D corresponding to the _extension telephone _DNia
N _ib , to DN _in are obtained, and this is the display 4 of the reception table 3.
(Step b). In addition, the extension telephone DN _ia
There even when not busy, even if there is no response within a predetermined time (step c), alternatively called telephone number DN _ib corresponding to the internal line telephone DN _ia, -Dn _in is determined, This is displayed on the display 4 of the reception board 3 (step b). Here, the memory 6 is provided with an alternative destination table having a configuration as shown in FIG. 3, for example. This alternative destination table contains information A indicating the telephone numbers of a plurality of extension telephones connected to the exchange body 1, information B indicating the status of each of these telephones, and the telephone numbers of the alternative destinations for the respective telephones. It consists of information C shown. When the extension telephone number DN _ia is dialed according to this alternative destination table, the state ST _{ia of the} telephone is obtained,
Also, the alternative destination telephone numbers DN _ib , DN _ic , to DN _in are required. The number of alternate destination for telephone extension DN _ia is to be defined according to the telephone extension DN _ia. The plurality of alternative destination telephone numbers DN _ib , DN _ic , to DN _in are assigned, for example, priorities, and are determined in order from the higher order. At this time, the state of the telephone at the alternative destination may be checked, and those in the busy state may be excluded from the alternative destination. If the extension telephone DN _ia is busy, or if the extension telephone DN _ia does not respond within a predetermined time, the alternative destination telephone number DN _ib , obtained from the alternative destination table described above. ~ DN _in is displayed, for example, as shown in FIG. 4 or FIG. FIG. 4 shows an example in which the extension telephone DN _ia and the alternative destination telephone numbers DN _ib ,..., DN _in are numerically displayed in a preset alternative destination telephone number display area of the display 4. . In BLF in Fig. 5 display 4, an alternative destination telephone number DN _ib, the operating state of the other telephone -Dn _in (busy /
(Empty) is displayed in a different display form. In this case, assuming that the telephone number of the vacant telephone is turned off and the telephone number of the busy telephone is driven to be lit, the telephone number of the alternative destination is blinked or illuminated. What should I do?
It goes without saying that the display colors may be different. By the way, the above description is an example of the display of the alternative destination when dialing from the reception desk 3, but the alternative destination can be displayed similarly when dialing from the telephone 10 with the display. FIG. 6 shows an example of a telephone 10 having a display, 11 is a display such as a liquid crystal display provided on the front panel of the telephone body, 12 is a plurality of function selection keys provided with LEDs, and 13 is a dial. 14 pads
Is a handset (handset). As in the case of the reception desk 3 described above, the information of the alternative incoming call destination can be displayed on the display-equipped telephone 10 by using the display 11 and the LED provided on the function selection key. FIG. 6 shows an example in which the telephone number (321) of the dial destination and the telephone number (322) of the alternative destination are displayed on the display device 11. At this time, it is convenient if the telephone is configured so that the LED of the function selection key 12 corresponding to the dial is turned on and the call is transmitted when the function selection key 12 is pressed. Thus, according to the present exchange system having such a function, the telephone number of the alternative destination for the dial destination is automatically displayed on the reception desk 3 or the telephone 10 with the display on which the dial operation has been performed. When the destination telephone 8 is busy or does not respond within a predetermined time, an incoming telephone call from an outside line or an internal telephone call can be promptly connected to the alternative destination. Therefore, it is possible to smoothly perform the outgoing / exchange operation of the telephone without causing the trouble as in the related art. In addition, it is possible to reduce the burden on the operator and the caller, and it is possible to expect an accurate telephone call and exchange processing. In addition, since the caller of the incoming call does not waste time arranging the call, the call charge can be reduced. Note that the present invention is not limited to the above-described embodiment. For example, the table configuration of the alternative destinations and the display format of the alternative destination telephone numbers may be determined according to the specifications. It is also possible to provide a function key corresponding to the displayed alternative called telephone number and add a function of automatically dialing the alternative called telephone number by operating the key. Further, when a plurality of telephones are grouped, another telephone in the same group may be determined as an alternative destination. In addition, the present invention can be variously modified and implemented without departing from the gist thereof. [Effects of the Invention] As described above, according to the present invention, the telephone number of the alternative destination can be automatically obtained when the destination is busy and when no response is made within a predetermined time. For example, if the destination cannot be answered because the destination is busy or the operator at the destination cannot be answered because he or she is away or on another phone, the operator can perform the setting operation. The phone number of the alternative destination is automatically displayed to the caller without performing any operation. That is, the speed and accuracy of the telephone exchange operation can be improved, the burden on the exchange can be reduced, and the service to the caller can be improved at the same time.
