  When the history type in the button incoming history information related to the same button incoming is “non-response”, the control unit 44 uses the button incoming history information as the non-response incoming history information through the storage control unit 43. 24 (step S19).

  When the non-response incoming call history information is stored in the non-response incoming call history storage unit 24, the control unit 44 sets a non-response incoming call history display request (step S20), and the button control unit 44 sets the button incoming call history information through the storage control unit 43. This is stored in the incoming call history storage unit 23 (step S21), and this processing operation is terminated.

  In addition, when the outside line incoming call is not a button incoming call in step S11, that is, if the terminal 44 is a terminal incoming call, the control unit 44 executes a normal terminal incoming call process (step S22), and ends this processing operation.

  Further, the control unit 44 determines that the incoming button call is not “non-response” in step S14, that is, “response”, and sets the history type in the received button call history information to “response” in step S13. (Step S23), the process proceeds to Step S16 in order to determine whether or not the line incoming for the button has been disconnected.

  If the incoming call history storage setting flag is not ON in step S17, that is, it is OFF, the control unit 44 ends this processing operation without storing the button incoming call history information related to the button incoming call.

  In addition, when the history type in the button incoming history information related to the button incoming call is not “non-response” in step S18, that is, “response”, the control unit 44 buttons the button incoming history information through the storage control unit 43. To store in the incoming call history storage unit 23, the process proceeds to step S21.

  According to the incoming call detection process shown in FIG. 7, when a button incoming call is detected, button incoming history information related to the button incoming call is created, and when the button incoming call is responded, the button incoming call history information is stored in the button incoming call history. The button reception history information is stored in the button reception history information, and the button reception history information is used as the non-response incoming history information. Since it is stored in the storage unit 24, when a button incoming call is detected, it is possible to store all the button incoming call history information related to the button incoming call regardless of whether the button incoming call is answered or not.

  FIG. 8 is a flowchart showing the internal processing operation of the CC 8 related to the unanswered incoming call history identification display processing of the telephone exchange device 1.

  The non-response incoming call history identification display process shown in FIG. 8 is stored in the non-response incoming call history storage unit 24 when the non-response incoming call history display request has been set in step S20 of the incoming call detection process shown in FIG. This is a process of identifying and displaying on the LEDs 13 of the history display buttons 11B of all MFTs 4 belonging to the incoming call history group of the response incoming call history information.

  In FIG. 8, the control unit 44 inside the CC 8 determines whether or not a non-response incoming response display request has been set (step S31). The setting of the unanswered incoming call response display request is a process performed in step S20 of the incoming call detection process shown in FIG.

  When the unanswered incoming call response display request has been set, the control unit 44 extracts a group number corresponding to the incoming call history group in the unanswered incoming call history information stored in the unanswered incoming call history storage unit 24 through the storage control unit 43. Then, it is determined whether or not the unanswered incoming call history information in the incoming call history group corresponding to this group number is in the unanswered incoming call history storage unit 24 (step S33).

  When the non-response incoming call history information in the incoming call history group is in the non-response incoming call history storage unit 24, the control unit 44 refers to the contents of the incoming call history group management table 22 shown in FIG. Terminal numbers of all the MFTs 4 are extracted, the table 13 of the button management table 21 shown in FIG. 3 is referred to, and the LEDs 13 corresponding to the history display buttons 11B of all the MFTs 4 in the same incoming call history group are displayed through the display control unit 42B. By controlling the display so as to blink in red (step S34), this processing operation is terminated. The user of the MFT 4 can recognize that a non-response button call has occurred in the same call history group by visually checking the LED 13 blinking red corresponding to the history display button 11B of the MFT 4.

  Further, if the unanswered incoming call history display request has not been set in step S31, or if there is no unanswered incoming call history information in the incoming call history group in step S33, the control unit 44 displays this unanswered incoming call history identification display. The processing operation related to the processing is terminated.

  When the control unit 44 detects a release operation through the button control unit 42A while the LEDs 13 corresponding to the history display buttons 11B of all the MFTs 4 in the same incoming call history group are blinking red in step S34, the non-response incoming call history is detected. The setting of the display request may be canceled and the LED 13 that is blinking red may be turned off through the display control unit 42B.

  According to the unanswered incoming call history identification display process shown in FIG. 8, when the unanswered incoming call history display request has been set, the incoming call history group information stored in the unanswered incoming call history storage unit 24 belongs to the incoming call history group. Since the LEDs 13 corresponding to the history display buttons 11B of all the MFTs 4 blink red, the user on the MFT 4 side automatically sees the LED 13 blinking red of the history display button 11B without performing a confirmation operation. Thus, it is possible to recognize that an unanswered button incoming call has occurred within the same incoming call history group.

  FIG. 9 is a flowchart showing the processing operation in CC 8 related to the button call history display processing of the telephone exchange device 1.

  The button incoming call history display process shown in FIG. 9 is performed in response to the button operation of the history display button 11B of the MFT 4 and the button incoming call history information and the unanswered incoming call history information in the incoming call history group to be displayed on the LCD display unit 12 of the MFT 4.

  When detecting the button operation of the history display button 11B on the MFT4 side, the control unit 44 determines whether or not the password request setting flag for requesting the authentication password of the incoming call history group to be displayed is ON (step S42). .

  When the password request setting flag is ON, the control unit 44 detects the input password on the MFT 4 side through the button control unit 42A (step S43), and based on the contents of the incoming call history group management table 22 through the password verification unit 44D, The authentication password corresponding to the incoming call history group is read out, the authentication password and the input password are collated (step S44), and it is determined whether or not the authentication password and the input password of the incoming call history group match (step S45).

  When the authentication password and the input password of the incoming call history group match, the control unit 44 stores the unanswered incoming call history information corresponding to the incoming call history group to be displayed in the unanswered incoming call history storage unit 24 through the storage control unit 43. It is determined whether or not there is (step S46).

  When there is unanswered incoming call history information corresponding to the incoming call history group to be displayed in the unanswered incoming call history storage unit 24, the control unit 44 displays the unanswered incoming call history information in the incoming call history group in the LCD display unit 12 of the MFT4. In order to display the screen, the process proceeds to the intra-group non-response incoming call history display process shown in FIG. 10 (step S47), and the processing operation related to the button incoming call history display process is terminated.

  If the control unit 44 does not detect the button operation of the history display button 11B in step S41, the control unit 44 ends this processing operation.

  In addition, when the password request setting flag of the incoming call history group to be displayed is not ON in step S42, that is, OFF, the control unit 44 does not perform the password authentication operation and does not answer the incoming call in the incoming call history group of the display target. The process proceeds to step S46 in order to determine whether or not the history information is in the unanswered incoming call history storage unit 24.

  If the authentication password and the input password of the incoming call history group do not match in step S45, the control unit 44 gives an error to the LCD display unit 12 of the MFT 4 that has executed the button operation of the history display button 11B through the display control unit 42B. This is displayed (step S48), and this processing operation is terminated. The user on the MFT 4 side can recognize the password mismatch on the MFT 4 side by an error display.

  In addition, when the unanswered incoming call history information in the incoming call history group to be displayed is not in the unanswered incoming call history storage unit 24 in step S46, the control unit 44 passes through the storage control unit 43 in the incoming call history group to be displayed. It is determined whether or not the button incoming history information is in the button incoming history storage unit 23 (step S49).

  When the button incoming call history information in the incoming call history group to be displayed is in the button incoming call history storage unit 23, the control unit 44 displays the button incoming call history information in the incoming call history group on the LCD display unit 12 of the MFT 4. Accordingly, the process proceeds to the intra-group button call history display process shown in FIG. 11 (step S50), and the processing operation related to the button call history display process is terminated.

  When the button incoming call history information in the incoming call history group to be displayed is not in the button incoming call history storage unit 23 in step S49, the control unit 44 displays a display without button incoming call history information in the incoming call history group to be displayed. It is displayed on the LCD display unit 12 of the MFT 4 that has executed the button operation of the history display button 11B through the control unit 42B (step S51), and the processing operation related to this button incoming history display processing is ended. Note that the user on the MFT 4 side can recognize that there is no button call history information related to button calls in the same group by displaying no button call history.

  According to the button incoming call history display processing shown in FIG. 9, when the button operation of the history display button 11B on the MFT 4 side is detected and the password authentication of the incoming call history group of the same display target is completed, the non-response in the incoming call history group When there is incoming call history information, non-answer incoming call history information in the same incoming call history group is displayed on the LCD display unit 12 of the MFT 4 and a group incoming call history display process is executed. When there is history information, the button reception history display processing for displaying the button reception history information in the same reception history group on the LCD display unit 12 of the same MFT 4 is executed, so that the user on the MFT 4 side displays the history display. Recognizing unanswered incoming call history information and button incoming call history information in the same incoming call history group according to the button operation of the button 11B It can be.
