DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call answering method for a key telephone apparatus, and more particularly to an incoming call answering method for a key telephone apparatus connected to a subscriber line of a public office telephone exchange and accommodating a plurality of key telephones.

[0002]

2. Description of the Related Art In the current public office telephone exchange system, telephone users can talk to any telephone user at any time. However, from the viewpoint of the user of a particular telephone, the user of the telephone of the other party to talk with is specified to some extent. In particular, the same applies to a user of an extension telephone of a private branch exchange or a user of a key telephone of a key telephone apparatus.
Therefore, calls between users of a particular relevant telephone are:
It is desirable that the priority be given to other priority.

In the conventional key telephone apparatus, when a plurality of calls are simultaneously received from a public office via a subscriber line, the display of the incoming call and the order of responding to the call in the key telephone apparatus are performed in the following order. In many cases, the order of calls arrives, or the order of the numbers of the accommodation lines accommodating the key telephones. The order in which the calls are answered has nothing to do with the importance of the incoming call or the user of the key telephone intended for the call. Therefore, even if a call with a higher priority is received, a large amount of time often elapses before the user of the key telephone set intended for the call answers.

In order to solve this problem, information on an incoming call is stored in a key telephone apparatus, and based on the stored information, the key telephone apparatus transmits information on the incoming call to a key telephone. It is necessary to transfer to a key telephone.

The technology relating to this is basically disclosed in German Patent Publication No. 2260023, and applied to Japanese Patent Application Laid-Open No. 59-020068 (Japanese Patent Publication No. 04-03241).

The technology disclosed in Japanese Patent Publication No. 2747912 (Patent No. 2747912) stores and accumulates information on a call received from a subscriber line (hereinafter referred to as "outside line") in a private branch exchange, and based on the information, establishes the subscriber line. The user of the extension telephone cannot specify the call to the extension telephone because the exchange connection to the extension telephone is not transferred to the exchange telephone connected to the extension telephone.

The technique disclosed in Japanese Unexamined Patent Publication No. 05-095396 is disclosed in Japanese Patent Application Laid-Open No. H05-095396. ), The name of the registrant of the calling telephone (hereinafter referred to as “the caller”), and the data of the time when the call arrived are stored as a call history, and the call history of the caller is stored in a call history table provided separately. If there is no registration data, it is newly registered as new data, and if there is already registration data of this caller in this call history table, every time there is an incoming call from this caller, the number of incoming calls is counted. Increase by one. This registration data is used when making a call to an outside line from the extension telephone of the private branch exchange. When automatically creating the telephone number book displayed on the display of the extension telephone, the registration data is transmitted to the extension telephone. This registration data is used to display the caller ID of the outside line in the order of the number of calls, and when a call arrives from the outside line,
This registration data is not used to display the caller number of the caller who made the call on the display of the extension telephone intended by the caller.

[0008]

Normally, a key telephone device corresponds to a window of a plurality of key telephones. For example, in the case of a key telephone device in which a complaint handling service is operated, the same complaint counselor can receive as much as possible. It is better to call the consultant, but there has been no solution to this problem.

According to the present invention, when a call is received from an outside line to a key telephone apparatus, based on the call history of the caller from the outside line, the display of the key telephone having a large number of calls from the caller is displayed on the display. An object of the present invention is to give priority to a caller number of a telephone that has originated this call so that the caller's call from the outside line can be preferentially connected to a key telephone intended by the caller. .

Referring to the flow of steps S103 and S104, the main unit 1 of the key telephone apparatus receives the incoming call from the external lines L1, L2,..., Lm via the external line interface unit 2, and the caller number is transmitted. When the caller ID is received by the caller ID identifying unit 6, the control unit 5 searches the call history table 7 and determines whether the received caller number exists in the caller numbers registered in the call history table 7. Or search.

Next, referring to S105, the control unit 5 stores the caller number of the incoming call and the response priority of each key telephone in the number display storage unit 9 as the search result. If the caller number of the call received from the outside lines L1, L2,..., Lm does not exist in the incoming call history table 7, it is determined that there is no response priority and stored in the number display storage unit 9. I do. At this time, if there is a caller number having the same response priority with the same number of responses in the incoming call history table 7, the response priority is set to a new order registered in the incoming call history table 7.

Next, referring to the flow of S106, the control unit 5 sets the display information of the caller number having the highest response priority for each key telephone as the caller number of the caller of the incoming call from the outside line. To each of the key telephones T1, T2,.
Tn is transmitted via the key telephone interface unit 4. Here, if there is no caller number with a response priority, display information of the caller number without a response priority is transmitted. In the key telephone set T1, the control unit T12 receives the above display information via the main device interface unit 4, and displays the caller number on the display unit T13.

Next, referring to the flow of S107 and S108, when a caller's number is displayed and a response operation (off-hook or response button press, etc.) is performed on the key telephone T1 displaying an incoming call, this message is displayed. The control unit 5 of the main device 1 recognizes the operation via the control unit T12 of the key telephone set T1, the main unit interface unit T11 of the key telephone unit T1, and the button telephone interface unit 4 of the main unit 1, and the control unit Reference numeral 5 designates an external line on which a call of the caller having the caller number displayed on the key telephone set T1 is receiving a call, is exchange-connected to the key telephone set T1 via the communication path switch 3.

More specifically, in the incoming call history table 7 of the key telephone set T1, the caller number AA is already registered as the table 1 as one response and the caller number BB as the table 2 as the response number 5 times. Is received, the key telephone device receives the incoming call from the outside line L1,
When receiving the caller number CC, the control unit 5 searches the incoming call history table 7, and as a result, the caller number CC does not match the caller number BB having the first response priority,
The caller number CC and no response priority for the key telephone set T1 are stored in the number display storage unit 9 as information regarding the incoming call from the outside line L1, and the caller number CC is displayed on the key telephone set T1.

Next, in the key telephone apparatus, the outside line L2
When the control unit 5 receives the incoming call from the telephone number BB and receives the caller number BB, the control unit 5 retrieves the incoming call history table 7 and stores it in the number display storage unit 9 as information on the incoming call of the outside line L2 as the key telephone T1. Caller ID BB for
Is additionally stored as the first response priority, and the caller number BB is displayed on the key telephone set T1.

Next, in the key telephone apparatus, the outside line L3
When the control unit 5 receives the incoming call from the telephone number AA and receives the caller number AA, the control unit 5 searches the incoming call history table 7 and stores the information on the incoming call of the outside line L3 in the number display storage unit 9 as the key telephone T1. The caller number AA is additionally stored as the second highest response priority. in this case,
For the key telephone set T1, the caller number BB has the highest response priority, so that the caller number BB is kept displayed on the key telephone set T1. Here, the key telephone T1
For response operation (off-hook or response button press, etc.)
Is performed, the control unit 5 exchanges and connects the outside line L2 having received the caller number BB to the key telephone set T1 via the communication path switch 3.

In this case, in the key telephone T1,
If any of the other key telephones T2,..., Tn performs a response operation to the incoming call before the response operation to the incoming call from the outside line L2, the number is stored in the number display storage unit 9. The information of the caller number BB is deleted, the caller number AA is stored as the first response priority, and the caller number AA is displayed on the key telephone set T1.

Here, if there is an unspecified call that has not been answered by the key telephone of this key telephone in the past, the caller ID of the caller of this call is changed to the unspecified call. As shown on the answer-only button phone,
It goes without saying that the control unit 5 and the control unit T12 can be operated.

Next, a method of creating the incoming call history table 7 will be described.

As described above, S101, S102, S
103, S104, S105, S106, S107, S
In accordance with the flow of 108, the control unit 5 of the main device 1 causes the external telephones L1, L2,
..., the caller number of the caller of the call received from Lm is displayed.

Next, according to the flow of S109, S110, and S111, when the telephone call is terminated on the key telephone T1, the control unit 5 sets the incoming call history table 7 of the key telephone T1.

Next, according to the flow of S112 and S113, the caller number registered in the incoming call history table 7 of the key telephone set T1 is compared with the caller number displayed on the key telephone set T1. If no caller number exists, the caller ID is registered as a new caller number in the last table number of the incoming call history table 7. At this time, when registering a new caller number, the number of responses is registered as one. Here, if the same caller number exists in the incoming call history table 7 of the key telephone set T1, the number of responses is increased by one, and the caller number is moved to the last table number in the incoming call history table 7. I do.

If the incoming call history table 7 has a limited storage capacity and there is no blank portion, the oldest first table registered in the incoming call history table at the time of registering a new caller ID is used. Delete the caller ID registered at the number location.

More specifically, in the incoming call history table 7 of the key telephone set T1, the caller number AA has been answered once at the table number 1 and the caller number BB has been answered at the table number 2 once. If the caller ID is registered as 5 times, a caller number CC that does not exist in the incoming call history table 7 is received from an outside line, and when a response operation is performed by the key telephone, the caller number CC is stored in the table number 3. It is registered as one response count in the location. As described above, when the caller ID is registered in the incoming call history table 7 and a call is answered from the caller with the caller ID BB, the caller registered in the table number 2 The number of responses of the number BB is set to 6 and the table number 3 is moved to the place of the table number 3, and the caller number CC registered in the place of the table number 3 is moved to the place of the table number 2.

[Second Embodiment] In a second embodiment of the present invention, in the flowcharts of S106 to S108 of the above-described first embodiment, the first priority is sent to the selected key telephone set. When displaying the user number,
When a predetermined button is pressed, the caller number of the next response priority is displayed, and by the response operation by pressing this button, the caller of the caller number of the next response priority is displayed. Answer an incoming call.

Further, the key telephone performs a response operation by pressing the button, thereby displaying the next-highest caller number, that is, the caller number having the third-highest response priority. The same applies to the display of the caller numbers of the third and subsequent response priorities.

For each key telephone, the administrator of the main unit can update the caller of the caller number of the response priority. In addition, the user of each key telephone can
When the caller number with the highest response priority is displayed, the caller number with the next response priority is displayed by pressing a predetermined button, and the response by pressing this button next time The operation responds to the first incoming call from the caller with the caller number of the next highest priority. With regard to the response operation of the response priority, the caller number can be cyclically and repeatedly displayed, thereby improving operability.

[Third Embodiment] The third embodiment of the present invention is different from the first and second embodiments described above in that the sender's name table in which the sender's number is associated with the sender's name is used. Provided in the main unit of the key telephone apparatus, when sending the called number to the key telephone, using the calling number as a key, searches the calling name table from the calling name table, and searches for the calling number. Is extracted, the name of the caller is displayed on the key telephone instead of the caller number. Further, not only the name of the caller, but also a classification such as friend, family, customer, colleague, etc. may be displayed.

As described above, in the key telephone apparatus, a history table of the caller ID of a call from an outside line that has responded in the past is automatically created for each key telephone, and the call is received from the outside line together with the incoming call from the outside line. Searches the response priority of the incoming caller ID, displays the caller ID with the highest response priority on the key phone, and performs a simple answer operation to the outside line that received the call from the caller of this caller ID. On the other hand, it is easily connected to a key telephone. Therefore, for example, in the telephone response business such as complaint processing, the same person who responded in the past can preferentially respond to the customer who responded in the past, and the efficiency of the telephone response business improves.

[0039]

According to the incoming call answering method of the key telephone apparatus of the present invention, the user of the key telephone does not need to prepare a caller ID registration table in advance, and can use the past response history to the caller. A call priority priority table is automatically created, which allows the key telephone device to receive multiple incoming calls simultaneously from outside lines.
Incoming calls with the caller ID with the highest response priority can be checked with the key telephone, and simple response operations such as off-hook and button pressing allow incoming calls from outside lines in descending order according to the response priority. There is an effect that a call can be answered.
