In the first embodiment, caller information such as the type of the caller is stored when a call is being received.

Next, the incoming call processing will be described with reference to the programming flowchart of the incoming call processing to the multi-function telephone 104 in FIG. First, when dialing an extension number, the CPU 101 analyzes the number and determines the extension terminal 105 to be called in step 401.

After determining the extension terminal that is receiving the call, it is determined in step 402 whether the extension terminal that receives the call is the multi-function telephone 104 or not. Here, when the extension terminal of the incoming call is other than the multi-function telephone 104, since the multi-function button 201 for displaying the incoming call is not provided, the calling process is normally performed.

If the extension terminal receiving the call is the multi-function telephone 104, the process proceeds from step 402 to step 403, where the function button management data 300 is checked by the CPU 101, and the function button used as the call display button is extracted. I do.

At this time, there are a plurality of incoming call display buttons to allow incoming calls at the same time. After the function buttons for displaying the incoming call are determined, it is determined in step 404 whether or not there is an empty button among the incoming call display buttons.

If there is an empty incoming call display button, the process moves from step 404 to step 405, where the function button management data 3 for the empty incoming call display button is set.
00, the incoming call state and the incoming / outgoing call information are written, and the corresponding visible lamps 204a to 204d of the incoming call display button are blinked to indicate that the incoming call is being received. Perform incoming call processing such as ringing.

If there is no empty incoming call display button in step 404, the process moves from step 404 to step 406, and a call cannot be made to the multi-function telephone 104, so that a busy tone is generated. Busy processing such as sending to other parties.

As described above, an incoming call to the multi-function telephone 104 can be received even if the terminal is busy, such as during a call, if there is an empty incoming call display button among the incoming call display buttons 201a to 201d. .

Therefore, the incoming call display buttons 201a to 201a
01d can be received at the same time.
When it is determined that the operator cannot answer the call for some reason, such as during a telephone call, the user presses a function button 202 for transferring an incoming call, and then displays the incoming call display button 20 for the incoming call.
By pressing any one of 1a to 201d, the caller is transferred to the voice recording device 106, and the caller records a message to the incoming extension terminal.

When there is a message recorded in the voice recording device 106, the visible lamp 203a of the function button 203 for displaying whether or not there is a message from the multi-function telephone 104 is turned on to notify the presence of the message. Multifunctional telephone 104
Accesses the voice recording device 106 and listens to the message.

FIG. 5 shows an example of the transfer button control data in the function button management data 300 for controlling the function button 202 for transferring the incoming call of the multi-function telephone 104. In FIG. 5, reference numeral 500 denotes control data for the function button for transfer assigned to the function button of the multi-function telephone 104, and identification for use with the function button for transfer is set.

First, in step 601 of FIG. 6, the CPU 101 monitors pressing of a function button of the multi-function telephone 104, and recognizes that the function button 202 corresponding to the function button has been pressed.

After the CPU 101 recognizes that the transfer function button 202 has been pressed, it is determined in step 602 whether or not there is an incoming call to the multi-function telephone 104. If it is determined in step 602 that there is no incoming call, there is no incoming call to be transferred, so that the function button 202 is ignored and transfer processing is not performed.

If there is an incoming call in step 602, the process moves from step 602 to step 603,
A transfer preparation process such as setting the control information in the transfer button control data 500 by turning on the visible lamp 202a of the function button 202 indicating that the function button 202 having the transfer function is enabled is performed.

After the transfer function button 202 is activated, the CPU 101 monitors in step 604 the press of the call display button of the function button 201 for displaying the call reception of the multi-function telephone 104.

At this time, if any of the incoming call display buttons 201a to 201d of the function button 201 is pressed,
Referring to the function button management data 300 corresponding to one of the pressed incoming call display buttons, it is determined whether the state of the incoming call display buttons 201a to 201 is incoming or not (step 6).
Identify with 05.

As a result of this identification, the incoming call display button 201a
When the incoming button of any one of the buttons 201 to 201d is not pressed or the function button is not operated, the timer of the transfer button control data 500 is monitored and the time during which the function button 202 for transferring is valid. In step 606, it is determined whether or not the number has exceeded.

If the timer has not expired in step 606, the process returns from step 606 to step 604 to monitor the function buttons of the multi-function telephone 104 again, and the processing from step 604 is repeated.

If the time during which the function button 202 for transferring is valid in step 606 ends, the process proceeds from step 606 to step 607, where the visible lamp 202a of the function button 202 is turned off, and the transfer button control is performed. Processing such as clearing the control information of the data 500 is performed, the transfer processing is canceled, and the transfer processing ends.

In step 605, if any of the incoming call display buttons 201a to 201d in the incoming call state is pressed, the extension terminal to which the call is transferred, for example, the voice recording device 106, is determined. The status is checked, and it is determined in step 608 whether the incoming call can be transferred to this extension terminal.

Here, if the transfer cannot be performed, for example, because the extension terminal is busy, the incoming call display buttons 201a to 201a are again displayed.
The processing from step 604 is repeated to monitor pressing of d.

In step 608, if the transfer destination extension terminal can receive a call while it is idle, the process proceeds from step 608 to step 609, and the call display button 201
Caller information is extracted from the function button management data 300 corresponding to a to 201d, the caller is switched to the transfer destination extension terminal, and the incoming call display buttons 201a to 201d
d, and turns off the visible lamp 202a of the function button 202 for transfer, and clears the control information of the transfer button control data 500 to complete the transfer process.

If the extension terminal of the transfer destination is the voice recording device 106, when the operator of the multi-function telephone 104 determines that the call cannot be answered, the incoming call is transferred and the message of the caller is left. The message can be heard by operating the multi-function telephone 104.

As described above, according to the first embodiment,
If there is an incoming call from a plurality of callers, the incoming call is displayed for each caller on the display means of the terminal, the caller is answered in response to the incoming call, and the CPU 101 displays the incoming call and displays the caller. Allocated and stored in the storage device 102, the CPU 101 constantly monitors whether or not the function button 202 for transferring from the terminal is operated, and when the function button 202 is operated, the data is stored in the storage device 102. In order to identify the caller who is calling and transfer it to another terminal, the terminal accepts incoming calls even when the terminal is in use, but does not forward all incoming calls, but does not answer the terminal operator Has the effect that the incoming call can be forwarded.

[0052]

According to the present invention, as is apparent from the above embodiment, incoming calls from a plurality of callers are simultaneously and individually displayed on the display means of the terminal to respond to the incoming call and displayed on the display means. The incoming call and the caller are allocated and stored in the storage device of the private branch exchange, and when a transfer operation is performed from the terminal, the CPU refers to the storage operation to identify the caller, and replaces the calling terminal with another terminal. The incoming call to the terminal is accepted even if the terminal is in use, and a response delay or an unanswerable incoming call can be easily received based on the judgment of the terminal operator. This has the effect that the connection can be switched to another terminal by operation.
