Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides a main device that accommodates a plurality of communication lines, and a main device that is connected to the main device and that responds to incoming calls on any of the plurality of communication lines. A system-type telephone device (generally called a business phone) consisting of a plurality of extension telephones that can accept calls at the main device, and an extension telephone usage indicator connected to the main device and displaying the reception/response status of each of the plurality of extension telephones. The present invention relates to a telephone reception status display device for telephones (often referred to as "phone reception status").

[Conventional technology]

Such business phones may be used to receive specific business requests. For example, at a telecommunications and telephone company, multiple communication lines belonging to a specific representative telephone number are housed in the main device, and users use that representative telephone number to apply for the transfer, new application, or cancellation of their telephones. We will accept all calls at once, and at that time, we will assign a responder (person in charge of reception duties) to each extension telephone. If there is a call request made to the communication line using the main telephone number, the bells of all telephone extensions will ring, so that the person answering any telephone extension will be able to answer the call. It has become.

In this case, it is naturally possible that only the answerer of a particular telephone extension always responds quickly, while the other answerers are playing around without answering. No technical measures were taken to address the imbalance.

Furthermore, in commonly used business phones, when calls are received on multiple communication lines and there is no response to any of them, it is determined which line has received calls the oldest (this is called the oldest line). ) was not available.

However, there is a known device called a call sequencer that responds with a voice response such as ``Please wait for a while'' to callers on unanswered communication lines, and one of its functions is to display the oldest line number. However, when used for business phones, the number of extension phones,
Therefore, although the number of responders was very large, the number of displays for the oldest line number was very small, making it physically difficult for many responders to see them.

In addition, conventional business telephones display the length of waiting time for the oldest line, the number of telephones that are accepting answers, the number of lines that have received calls but have not been answered, and the number of lines that have received calls but have not been answered. The response rate, which is the ratio of incoming calls answered to all calls, is not displayed, and when the person answering the extension telephone leaves his or her desk and becomes unable to answer,
There was no means to display this information.

[Problem to be solved by the invention]

In other words, when conventional business phones are used for reception of specific business, there is a risk that the burden will be biased towards a specific telephone extension (answerer), and since there is no indication of the oldest line number, It is not possible to respond and equalize the service, and it is not possible to display the number of telephones that are accepting responses, the number of lines that have received calls but have not been answered, and the display of the response rate. Because this was not done, it was not possible to collect these statistics and use them as data for service improvement, and there were cases where the person answering the extension telephone (hereinafter also referred to as the "answerer") was away from his or her desk and was unable to respond. However, since this information was not displayed, the administrator was unable to determine the number of telephone extensions that could actually answer the call, making the service extremely poor in terms of usability.

An object of the present invention is to provide a system-type telephone device (business phone) used for receiving a specific business by giving the responders of each extension telephone a system telephone device (business phone) that allows all responders to respond equally.
By informing each person of their chance to respond and displaying various related information, it is possible to improve the response reception service, and to easily obtain materials for improving the response reception service, making it easier to use. Another object of the present invention is to provide an excellent telephone reception status display device.

[Means for Solving the Problems] To achieve the above object, the present invention provides a main device accommodating a plurality of communication lines, and a plurality of extension telephones connected to the main device, wherein the plurality of communication lines the plurality of extension telephones capable of responding to and accepting incoming calls from any of the above;
an extension telephone usage indicator connected to the main device and displaying reception/response status of each of the plurality of extension telephones;
As a call reception status display device for a system-type telephone device that operates from a remote control system, a dedicated display device dedicated to each extension telephone corresponding to each of the extension telephones, a common display common to the whole, and a plurality of telephone reception status display devices housed in the main device are used. The present invention has constructed a device consisting of means for monitoring the line status including incoming, answering, and disconnecting of each communication line, and a processing device for display.

[Effect]

The display processing device receives the line status monitoring information of each of the plurality of communication lines from the monitoring means and the reception/response status information of each extension telephone from the extension telephone usage indicator, and displays the response reception information for the incoming call. Determine the next extension telephone from the reception/response status information of each extension telephone, and display that it is the dedicated display 6 of the extension telephone;
At that time, if there are multiple unanswered incoming lines,
At least the oldest line number and the oldest line time, which is the waiting time of the oldest line, are calculated and displayed together with the response status of each extension telephone and the number of answering telephones.
Calculating and displaying at least the blockage status of a plurality of communication lines, the number of unanswered incoming lines, the response rate, the oldest line number, and the oldest line time on the common display. .

When the corresponding extension telephone 40-j of the desk display j whose response order display lamp and response order display buzzer are activated goes off-duty (picks up the receiver) and answers, the main unit W30 of the business phone detects this. The corresponding lamp (not shown) of the extension usage indicator 50 corresponding to the extension telephone 40-j is turned on to indicate that it is in use.

In addition, a DC loop is installed in the communication line (19 20 ), and this is detected on the exchange side, and a connection is made to the calling side, and the ringing tone is stopped and the polarity of the line J is reversed.

The calling signal detection circuit 121 and the line state detection circuit 123 detect this change in the communication line J, and send an output signal to the response monitoring circuit 124. Furthermore, the response monitoring circuit 124 outputs a response signal to the control unit 119 via the I/O boat 113, and the control unit 119 stops timer measurement regarding line I, and at the same time, the memory 115 indicates that line I is in response use. At the same time, the control unit 119 is displayed on the display 13.
, the oldest line time is updated via the I/O boat 114, the J-th lamp is lit to indicate that the extension telephone is in use, and the display on the number-of-use display section 13b is counted up.

At the same time, the line response lamp I is changed from blinking to lit.

Similarly, for the display 12-i, the oldest line time is updated, the operation of the response order display lamp and the response order display buzzer is stopped, and the display 12 for which the next response order display lamp should be lit is selected. Then, the extension telephone with the longest idle time at the current time is detected from the extension monitoring circuit 112, I/O port 113, memory 115, and arithmetic processing unit 117.
The response order display lamp on the display I2 corresponding to that extension telephone is turned on via the 0 port 114.

This series of operations is repeated from receiving a line call to answering the extension telephone, but when waiting for the line from receiving the line call to answering the line, the memory 115, arithmetic processing unit 117, control unit 119, I/O The display on the waiting line number display section 13d is counted up via the O port 114.
