(Integrated circuit) A memory or the like can be used.

In the embodiment of the present invention, first, a special number "@" and a transfer destination FAX number "XX" are transmitted from the maintenance console terminal 17 as FAX erroneous call transfer registration special number information A.
"Xx" is registered in the storage device 13 of the private branch exchange 1 in advance.

In a state where the general extension telephone 15 is idle, there is an incoming call B from the public network 2 via the office line trunk 14, and the incoming call destination number information ("XX-XXX") is received.
○)), the connection destination is the general extension telephone 15,
The CPU 12 calls the general extension telephone 15.

The general extension telephone 15 called by the incoming call from the office trunk 14 responds to the office trunk 14. In response, the office trunk 14 and the general extension telephone 15 enter the communication state a, and when the responding general extension telephone 15 hears a FAX signal via the office trunk 14, the responder of the general extension telephone 15 responds. Is F
Knowing that the call is from the AX, the responder performs a hooking operation + a dial operation C of the special number “△△” on the general extension telephone 15 in order to transfer an erroneous call from the FAX to the FAX terminal 16.

By this dial operation C, the CPU 12
Analyzes the special number information memory 20 with the received special number 22 and, as a result, determines that the request is a registration request from the FAX erroneous incoming call transfer service information 21 read from the special number information memory 20. The CPU 12 reads out the transfer destination FAX number information 31 registered in advance from the maintenance console terminal 17 from the transfer destination FAX number information memory 30 (steps S1 to S4 in FIG. 8).

The CPU 12 reads out the caller ID information 61 stored in the caller ID information storage memory 60 at the time of an incoming call in the storage device 13 by using the incoming call trunk information 62 when receiving an incoming call from the central office trunk 14 ( FIG. 8 steps S5, S

Step S7).

Thereafter, the CPU 12 releases the communication path between the office trunk 14 and the general extension telephone 15 which are engaged in a call, connects a ringing tone to the office trunk 14, and sets the read-out destination FAX terminal 16 to a calling state. State transition. Further, the CPU 12 connects the service setting completion sound to the general extension telephone 15 which has performed the FAX erroneous incoming call transfer request operation, and the person handling the extension telephone puts the receiver on-hook.

After the transferred incoming call of the trunk 14 is answered by the FAX terminal 16 to which the transfer is to be made, a transmission / reception confirmation sequence based on a FAX signal is performed. If the transmission is normally confirmed, FAX data is transmitted. (Step S in FIG. 8)
8).

After the completion of FAX data transmission, the CPU 12 restores the communication state between the central office trunk 14 and the FAX terminal 16. The FAX terminal 16 to which the transfer is to be made establishes an outgoing connection based on the caller number information 61 of the caller number storage information memory 60 at the time of the incoming call of the storage device 13 and sends out a FAX signal for notifying that there is an erroneous call. (Step S9 in FIG. 8).

When the above-mentioned FAX erroneous call forwarding service is implemented, if the FAX terminal 16 of the transfer destination cannot be normally connected to the FAX terminal 16 of the transfer destination due to a busy state or some other reason, a retransmission process is performed by the sending FAX. The following is a description of the case.

In a state where the general extension telephone 15 is empty, there is an incoming call D from the public network 2 via the central office trunk 14, and the connection destination by ("XXX-XXX") is the general extension telephone 15. In some cases, the CPU 12 is connected to the general extension telephone 1
In step S11, S12 of FIG. 9, it is checked whether the FAX 5 is requesting the FAX incorrect call transfer by sending the destination extension information 42 to the FAX wrong call transfer request information memory 40. ).

If the FAX erroneous incoming call transfer request is being made, the CPU 12 reads out the incoming caller ID information 61 from the incoming caller ID information storage memory 60 (step S in FIG. 9).
13, S14), the caller number information 51 registered in the call forwarding caller number information memory 50 is read out by the incoming call destination extension information 52 (steps S15, S16 in FIG. 9).

The CPU 12 determines in steps S13 and S1 described above.
The caller number information read out in step 5 is compared with each other (step S17 in FIG. 9), and if the caller number information matches (step S18 in FIG. 9), the transfer destination FAX number information memory 30
Then, the transfer destination FAX number information 31 is read using the incoming call destination extension information 32 (step S19 in FIG. 9). CPU1
2 connects the incoming call from the central office trunk 14 to the read destination FAX terminal 16 (step S in FIG. 9).
20).

Separately from this, when the FAX erroneous incoming call transfer information is registered, the CPU 12 updates the erroneous incoming call transfer set time management memory 70, and keeps a predetermined time from the timer information 71 of the erroneous incoming call transfer set time management memory 70. After the recognition, the call forwarding destination caller number information memory 50 of the storage device 13 and the FA
The registration information in the X incorrect incoming call transfer request information memory 40 is deleted. Thereafter, even if there is an incoming call at the caller number to be transferred, the transfer to the FAX terminal 16 is not performed.

As described above, in response to an erroneous incoming call from a facsimile, the telephone handset is left as it is without terminating the call.
After the hooking operation, the special number is dialed to transfer and connect to the designated FAX terminal 16, and when the transfer cannot be performed normally due to the transfer destination call or the like, the incoming call from the same terminal on the calling side is repeated several times. If there is, it can be connected to the FAX terminal 16 of the transfer destination.

When the call is normally transferred to the facsimile terminal 16, it is possible to prevent the recurrence of the wrong call by notifying the caller of the wrong call from the destination facsimile terminal 16. And interruption of business can be prevented.

Further, the FAX erroneous call transfer function clears a transfer connection request to the FAX terminal 16 after a predetermined time elapses, so that the caller's terminal has both a FAX function and a general telephone function. Can also respond.

[0042]

As described above, according to the present invention, in the private branch exchange accommodating the extension telephone and the facsimile terminal, a dial operation is performed to indicate that the extension telephone has received an erroneous call from an external facsimile terminal. When a call is received, the incoming call from the external facsimile terminal is transferred to the pre-registered facsimile terminal in the own device, the caller ID information of the external facsimile terminal is stored, and all the data is stored in the facsimile terminal in the own device. By transmitting a facsimile signal for notifying the external facsimile terminal stored after receiving the facsimile signal from the facsimile terminal in the own device, the recurrence of the erroneous call from the external facsimile terminal can be prevented. Thus, there is an effect that business interruption can be prevented.
