Next, the operation of the entire key telephone system according to the present invention will be described with reference to FIG. FIG. 5 is a sequence diagram showing an outside-line incoming call processing operation for notifying the key telephone and displaying the other party information at the time of incoming call using the database of the server. First, in the external line I / F unit 11 of the main device 1, the telephone line 1
When an incoming call is detected in any one of the key telephones 2A to 2N, the function processing unit 12A of the main control unit 12 performs one or more key telephones selected from the key telephones 2A to 2N as an incoming call notification process.
For example, the key telephone 2A is notified that an outside line is being received, and a ringtone is output and an incoming call is displayed.

At the time of the incoming call, if the caller number is notified from the telephone line 10 and detected by the external line I / F unit 11, the function processing means 12A performs a destination information search process using the caller number as a search telephone number. (See FIG. 5). First,
A request is made to the server 3 for a search for destination information (first destination information) corresponding to the detected caller number (step 10).
0). This search request is transmitted to the server 3 via the communication I / F unit 15 and the data communication path 30. The server control unit 32 of the server 3 receives the search request via the communication I / F unit 31 and searches the database 33 for destination information corresponding to the caller number included in the search request.
The destination information is returned to the main device 1 as a search result by a route reverse to the search request. If the corresponding destination information could not be searched, a search failure is returned as a search result.

In parallel with this, the function processing means 12A of the main device 1 searches the main storage unit 14 for destination information (second destination information) corresponding to the detected caller number (step). 101). Then, the search result is received from the server 3 (step 102: YES). After searching for the destination information in both the server 3 and the main storage unit 14 in this way, it is first determined whether the destination information has been obtained from the main storage unit 14 (step 103). If the corresponding destination information is not stored in the main storage unit 14 and the search fails (step 103: NO), it is determined whether the destination information has been obtained from the server 3 (step 10).
4).

Here, if the corresponding destination information is stored in the server 3, that is, if it is not stored in the main storage unit 14 but only in the server 3 (step 104: YES), The destination information obtained from the server 3 is notified to the key telephone 2A and displayed on the screen display unit 27 (step 105). FIG. 6 is a display example of the destination information. As the destination information, not only the destination name but also a telephone number may be displayed together. Thereby, even when the destination information corresponding to the caller number is not stored in the main storage unit 14, the caller can be concretely notified using the information of the server 3 effectively. If the server 3 fails in the search (step 104: NO), the caller ID is displayed through the key telephone 2A (step 10).
6).

In step 103, when the destination information is obtained from the main storage unit 14 (step 103: YES),
It is determined whether the destination information has been obtained from the server 3 (step 107). Here, when the search fails in the server 3, that is, when the search is not stored in the server 3 and the main storage unit 1
4 (Step 107: N
O), the destination information obtained from the main storage unit 14 is notified to the key telephone 2A and displayed on the screen display unit 27 (step 1).
08). Thereby, even when the destination information corresponding to the caller number is not stored in the server 3, the main storage unit 14
Information can be used to effectively notify the sender.

In step 107, when the destination information is obtained from the server 3, that is, when the destination information is obtained from both the main storage unit 14 and the server 3 (step 107:
YES), it is determined whether the other party information matches (step 109). Here, if the two pieces of destination information match (step 109: YES), one of the destination information, for example, from the server 3 is notified to the key telephone 2A and displayed (step 110).

At step 109, if the two search results do not match (step 109: NO), the other party information obtained from the higher priority of the main storage unit 14 and the server 3 is notified to the key telephone 2A. And display (Step 1
11). This priority is set and registered in advance.

Subsequently, it is determined whether or not the confirmation flag added to the destination information obtained from the main storage unit 14 indicates "OFF", that is, indicates that the confirmation has not been made (step 11).
2). Here, if the confirmation flag indicates “OFF”, that is, indicates unconfirmed (step 112: YES), it is registered that the partner information updating process for updating and matching the mismatched partner information is necessary. (Step 113).
If "ON", that is, the confirmation has been completed (step 112: NO), it is determined that it is not necessary to update the mismatched partner information, and the series of processes ends.

Next, the destination information updating process will be described with reference to FIG. FIG. 7 is a flowchart showing the destination information updating process. This destination information update processing is performed at a predetermined time, for example, after the end of a call or when updating system information, for the information registered in step 113 of FIG. First, an inquiry screen as shown in FIG. The notification is displayed on the telephone 2A (step 120).

In response to this, when an instruction indicating the necessity of updating is returned from key telephone 2A (step 12).
1: YES), the main storage unit 1 based on the destination information of the server 3
4 is updated (step 122). on the other hand,
If an instruction indicating that updating is unnecessary is returned (step 12
3: YES), the confirmation flag added to the destination information in the main storage unit 14 is set to "ON" and registered (step 1).
24). Thereafter, even if the destination information between the main storage unit 14 and the server 3 corresponding to the same caller number does not match, the update processing inquiry is not performed.

As an actual processing example, when the destination information shown in FIGS. 3 and 4 is stored in the server 3 and the main storage unit 14, the caller number is "03-3493-74".
In the case of "9x", the same destination information "Inage" is obtained from the server 3 and the main storage unit 14. In this case, in step 110 of FIG. 5, the other party information, for example, the destination information from the server 3 is notified to the key telephone 2A. When the caller number is “03-3494-722x”, the other party information “Horii” is obtained only from the main storage unit 14. In this case, the destination information is notified to the key telephone 2A in step 108 of FIG.

The caller number is "03-3494-6".
87x ”, the destination information“ Watanabe ”only from the server 3
Is obtained. In this case, the destination information is notified to the key telephone 2A in step 105 of FIG. Further, when the caller number is “03-3494-736x”, different destination information can be obtained from the server 3 and the main storage unit 14. In this case, the destination information of the higher priority is notified to the key telephone 2A in step 111 of FIG. At this time, since the confirmation flag is “ON” (step 112: NO), the destination information “Onozuka” of the main storage unit 14 is not updated with the destination information of the server 3.

In the above description, an example has been described in which a caller number notified from the telephone line 10 at the time of an incoming call is used as a search phone number, and the destination information is searched from the caller number. However, the present invention is not limited to this.
For example, in addition to the incoming call, a telephone number indicating the other party to be interrupted in the case of an external call interruption, a telephone number indicating the other party who recorded the message with the answering machine service at the exchange, etc.
The present invention can be applied to the telephone number notified from the telephone line 10 in the same manner as described above. The same applies to a search telephone number other than the telephone number notified from the telephone line 10.
