It is sent back to the private branch exchange PBX via board B1 and twisted pair wire B2.

Next, the incoming call notification flow of the above embodiment will be explained with reference to the flowchart of FIG. In FIG. 2, steps S5 and S6 are processes executed by the incoming call data conversion personal computer C, and step S8 is a process executed by the facsimile FA.
This is a process executed by Xi, and other steps Si(i
=1, 2,...) are processes executed by the private branch exchange PBX. When the incoming call notification flow shown in FIG. 2 is started, in step S1, incoming call data, that is, data regarding the originating telephone number, the terminating telephone number, and the date and time of the incoming call are detected. Next, in step S2, the incoming call data is stored. Next, in step S3, it is determined whether the incoming call can be connected to the incoming telephone Ti. This judgment is YES (if the incoming telephone Ti answers)
If the answer is YES, and the originating telephone is disconnected before the incoming telephone Ti responds, the answer is NO. If the answer is no, the process moves to step S4.

[0013] In step S4, the incoming call data (calling telephone number, receiving telephone number, and date and time of incoming call) is
The data is transferred to the incoming call data conversion personal computer C via the S-232C cable K (see Figure 1). In step S5, the incoming call data conversion personal computer C converts the received incoming call data into image data that can be received by the facsimile FAXi, that is, incoming call image data. Next, in step S6, the incoming call data conversion personal computer C sends the converted incoming call image data to the facsimile FAXi located near the incoming telephone set Ti of the incoming call, using the FAX board B1 and the twisted pair wire B2. The data is sent (returned) to the private branch exchange PBX via the private branch exchange PBX. The incoming call data conversion personal computer C converts data to the facsimile FAXi located near the incoming telephone number Ti in order to send data to the facsimile FAXi located near the incoming telephone number Ti, as described above.

Effects of the Invention The above-described incoming call notification system of the private branch exchange of the present invention allows the incoming call to be notified when the incoming call cannot be connected to the incoming telephone because the incoming telephone is busy or the user of the incoming telephone is absent. A facsimile reception sheet is output from a predetermined facsimile machine on which incoming call data regarding the originating telephone number, the receiving telephone number, and the date and time of incoming call are written. Since the receiving telephone number is written on the facsimile receiving form, the facsimile receiving form can be delivered to the location of the receiving telephone. Therefore, the user of the incoming telephone, that is, the extension subscriber on the called side, can be notified of information regarding the incoming call. Therefore, the user of the incoming telephone that could not connect to the incoming call at the time of the incoming call can know the originating telephone number of the incoming call data from the facsimile reception form. Therefore, the user of the incoming telephone that could not connect to the incoming call can inquire about the business to the calling telephone number, if necessary.
