BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile transfer method, and more particularly to a PBX facsimile transfer method for providing a mail service.

[0002]

2. Description of the Related Art In the current facsimile communication, a transmission original is temporarily stored in a facsimile terminal and is transmitted to a plurality of destinations, or is automatically redialed when the destinations are busy. It is more convenient. If the sender mistakenly dials the telephone from such a facsimile terminal, or if the telephone number is stored in the memory in correspondence with the abbreviated number and transmitted to the memory, the telephone unconditionally arrives and the telephone emits a beeping carrier signal To do. in this case,
The facsimile terminal automatically disconnects the line because there is no response command from the other party.

[0003]

When the facsimile terminal mistakenly calls the telephone, there is no means for the receiver to access the sender, and therefore the mistake cannot be conveyed to the sender. Also, if you call the phone by mistake,
The line is automatically disconnected, but the facsimile terminal cannot determine the wrong number. From the above, when the line is automatically disconnected, the sender makes an incorrect call many times without knowing the reason for disconnecting the line, and in the case of memory transmission, the facsimile terminal makes many mistakes due to the redial function. Call the other party. For this reason, the other party receives a beeping sound of the carrier signal each time, resulting in great annoyance. From the above, it is an object of the present invention to provide a facsimile transfer system capable of preventing continuous incoming calls to a telephone due to an incorrect number from the same facsimile terminal.

[0005]

The correspondence table TFX of the telephone numbers and the facsimile numbers of the groups G1, G2, ... Is registered in the PBX 11. A predetermined facsimile terminal 13 calls, for example, a telephone 15n, and the telephone 1 responds to the call.
5n sends the special number for facsimile transfer to the PBX. P
Upon receiving the special number, the BX obtains the number of the receiving facsimile terminal 14 corresponding to the telephone 15n from the correspondence table TFX, and notifies the mail system 12 of the number of the receiving facsimile terminal 14. Further, the PBX connects the sending side facsimile terminal 13 and the mail system 12, and the mail system 12 stores the facsimile communication data sent from the sending side facsimile terminal, and after the storage, calls the receiving side facsimile terminal 14 to store the data. The existing facsimile communication data is automatically transmitted. In this way, even if the telephone is erroneously received by the telephone, the data from the facsimile terminal is received. Therefore, it is possible to prevent the facsimile terminal from continuously receiving the telephone. Further, since the facsimile number of the sender is printed on the received facsimile paper, the error can be notified. Further, when the sender does not know the number of the destination facsimile terminal or is communicating, the facsimile communication data can be transmitted by calling the destination telephone to perform the above operation.
