The present invention has been developed in consideration of these circumstances, and its purpose is to inform the switchboard operator or caller of an alternative destination telephone number, thereby facilitating the smooth telephone and switching operations. The purpose of this invention is to provide an alternative call destination display method.

[Structure of the Invention] (Means for Solving the Problems) The present invention stores in advance an alternative destination telephone number for an extension telephone that is handled by a reception desk or a telephone with a display device, When an extension phone number is dialed from a phone or display phone, an alternative call destination phone number for the extension phone is obtained from the memory, and, for example, a predetermined alternative call destination phone number display area of the reception desk or display phone is dialed. Display phone number or BLF at reception desk
The telephone number corresponding to the alternative destination is displayed in a different display format from other display formats.

(Function) According to the present invention, when an extension telephone is dialed from a reception desk or a telephone with a display, the telephone number of an alternative destination for that extension telephone is set to a vacant state among the alternative destinations registered in the memory, for example. You will be asked to select a telephone and the telephone number will be automatically presented to the operator or caller. Therefore, when the destination telephone is busy, it is possible to quickly and accurately transfer the call to the alternative destination telephone.

(Example) Hereinafter, one 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 constructed by applying the method of the present invention.

In FIG. 1, 1 is a private branch exchange main body, and a reception desk (attendant; ATT) 3 is connected to this private branch exchange main body 1 via a reception desk control circuit 2. In the figure, 4 is a reception desk 3.
This is a display device such as a BLF installed in the Further, 5 is a central control unit called CC, and this central control unit 5 controls the telephone exchange operation via the private branch exchange main body 1.

Further, 6 is a memory that stores exchange operation programs and various control information.

A plurality of extension telephones 8a, .about.8n are connected to such an exchange main body 1 via subscriber circuits 7a, .about.7n, respectively, and subscriber circuits 7n+1. 7x is connected to an extension telephone 10a with a display, and 10a and 1k, respectively, and the private branch exchange main body 1 is connected to a central office line trunk circuit 9a.

A central office line (external line) is connected through 9n.

In a switchboard system configured in this way, normally, an incoming call from an outside line is answered from the reception desk 3, and the telephone number 8.10 of the called party requested by the incoming call is dialed from the reception desk 3. The telephone connection is made. Further, an extension call is made by directly dialing the telephone number of the other party from the telephone set 8.10 to establish a telephone connection.

However, in this method, when the above telephone intermediary is carried out, the reception desk 3
Then, for example, the processing procedure shown in FIG. 2 is executed. That is, when the reception console 3 dials the extension telephone 8 that has requested an incoming call, it is first determined whether the extension telephone DN is in a busy state (step a). As a result of this determination, if the extension telephone DN is in a busy state, an alternative destination telephone number a DN - DN corresponding to the nuclear A telephone DN is obtained, and this is determined by the reception desk ib.
' is displayed on the display 4 of ln 3 (step b). Furthermore, even if the extension telephone DN1a is not in a busy state and there is no response within a predetermined time (step c), the telephone number DN-DN of the alternative destination corresponding to the extension telephone DN1a is ib' I
n, and this is displayed on the display 4 of the reception desk 3 (step b).

Here, the memory 6 is provided with an alternative destination table having a structure as shown in FIG. 3, for example. This alternative destination table includes information A indicating each telephone number of a plurality of extension telephones connected to the exchange main body 1, and information B indicating the status of each of these telephones.

The information C includes information C indicating the telephone number of an alternative destination for each of the above-mentioned telephones.

According to this alternative destination table, when an extension telephone number DN is dialed, the status ST of the telephone is determined, and the alternative destination telephone number DN DN,...D
N, is now required ib' lc
1n is there.

The number of alternative call destinations ia for the extension telephone number DN is determined according to the extension telephone number DN. and multiple alternative destination phone number DNs.
, DN, , ~DN, for example +b'
+c tnPriority is assigned, and the values are obtained in order from the highest priority. At this time, the status of the telephones of the alternative destinations may be checked, and those that are in a busy state may be excluded from the alternative destinations.

Thus, if the extension DN ia is busy, the extension DN also returns within a predetermined time.

ia does not respond, the alternative destination telephone number D N i b determined from the above-mentioned alternative destination table.

~DN, is, for example, In as shown in FIG. 4 or FIG. displayed.

FIG. 4 shows the extension telephone DN, ia, and the alternative destination telephone number DN - DN displayed in the preset alternative destination telephone number display area of the display 4 in numbers ib.
'1n This is an example of display.

Further, in FIG. 5, on the BLF of the display 4, the alternative destination telephone number DN - DN, ib' of another telephone is displayed.
+n This is an example of displaying in a display format different from the operating state (busy/vacant). In this case, if the phone number of the idle phone is turned off and the phone number of the busy phone is turned on, the phone number of the alternative destination will be turned on or off with a high brightness. Just do it like this. Of course, the display colors may also be different.

By the way, although the above explanation is an example of displaying an alternative destination when dialing from the reception desk 3, alternative destinations can be similarly displayed when dialing from a telephone IO equipped with a display device. Figure 6 shows a telephone 10 with a display.
An example is shown in which 11 is a display such as a liquid crystal display provided on the front panel of the phone body, and 12 is an LED.
13 is a dial pad, and 14 is a handset.

Similar to the case of the above-mentioned reception desk 3, such a telephone with a display device 10 can also display information on an alternative destination using the display device 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 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 made when the function selection key 12 is pressed.

Thus, according to the present exchange system equipped with such functions, the telephone number of the alternative destination for the dialed destination is automatically displayed on the reception desk 3 or the display telephone 10 where the dialing operation is performed. If the dialed telephone 8 is busy or does not respond within a predetermined time, an incoming call from an outside line or an extension call can be quickly connected to the alternative destination. Therefore, it is possible to facilitate telephone call origination and exchange operations without causing problems as in the conventional case. Furthermore, it becomes possible to reduce the burden on operators and callers, and it becomes possible to expect accurate telephone outgoing and exchange processing. Furthermore, since the caller of the incoming call does not have to waste time in handling the call, it is possible to reduce the cost of the call.

Note that the present invention is not limited to the embodiments described above. For example, the table structure of alternative destinations and the display format of 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 destination telephone number and add a function such as automatically dialing the alternative destination telephone number by operating the key. Furthermore, if a plurality of telephones are grouped, other telephones within the same group may be determined as alternative destinations. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] As explained above, according to the present invention, it is possible to automatically obtain the telephone number of an alternative destination, so that it is possible to speed up and improve the accuracy of telephone exchange operations, and to save the operator's time. This makes it possible to reduce the burden and at the same time improve service to callers.
