As described above, by performing the communication control processing in the facsimile machine 1, the facsimile machines 1 as shown in FIG. 3 are connected to the G3 extension, the G4 exterior and the G3 exterior by a plurality of lines. The call processing is performed in ascending order of the communication cost among the call numbers registered in the parameter memory 4 corresponding to each line, so that the communication cost can be surely reduced.

When a call connection by redialing fails or when an error occurs during modem training after the call connection, the calling number registered in a series of parameter memories 4 of the calling destination is stored. Since the error report or the communication history information is recorded and output, the operator of the facsimile apparatus 1 can recognize the state of the call destination by checking the error report and the communication history information, and can take immediate action. Since the redial process is automatically executed, the re-call operation of the operator can be omitted.

Steps P12 to P21 in the dashed line in the flow chart of FIG. 4 can be replaced with the flow chart shown in FIG. 5, and this processing will be described. In FIG. 5, the same step processing portions as those in the flowchart of FIG. 4 are denoted by the same step numbers. That is, in the present embodiment, the only difference is that step P22 and step P23 surrounded by a circle are added, and a redialing process is added when a call is made by a G3 extension and a call is made by a G4 outside line, respectively. A redial calling process is executed each time an outside line is called.

[0043] Thus, it is possible to save the trouble of the operator of the recalling operation as well, Ru can be shortened interval redial outgoing call processing.
