Description

  The present invention relates to a key telephone apparatus or a private branch exchange comprising a main apparatus accommodating one or more external lines and a plurality of extensions and a plurality of extension telephones connected to the extensions, and a calling number of a specific caller when an external line is received It is related with the telephone system which enables the function (henceforth a "priority incoming call") to answer and receive a call with priority.

  In a key telephone apparatus or private branch exchange, incoming calls from multiple external lines and internal lines can be made simultaneously. However, except for dial-in incoming calls, in general, incoming calls are displayed and answered in response to incoming calls. When there are many incoming calls, responses to incoming calls from important customers may be delayed.

Therefore, in a terminal or a private branch exchange that can receive a calling number when receiving an incoming call and simultaneously accept a plurality of incoming calls, a specific number is registered and recorded in advance, and the calling number received when receiving an incoming call is compared with the specific number, There is a response order selection method characterized in that the priority order of responses is changed according to the collation result (for example, Patent Document 1).

Japanese Patent Laid-Open No. 02-090851

  However, if a specific number for priority call is set in the response order selection method described above, if there is an incoming call from a specific number, it will always respond to an incoming call from the specific number. It becomes inconvenient when waiting for an incoming call from a partner who is not.

In addition, when a specific number for priority incoming calls is set in the main unit of the private branch exchange or key telephone, all telephones connected to the extension will respond to incoming calls with a specific number, so it is used in multiple departments. Private branch exchanges and key telephone systems have the disadvantage that unnecessary priority calls occur.

  In order to solve the above-mentioned problem, the first invention is a telephone system comprising a main apparatus that accommodates one or more external lines and a plurality of extensions, and a plurality of extension telephones that are connected to the extension lines. Specific telephone number storage means for storing a specific number for priority incoming calls, and specific number analysis processing means for analyzing whether the other party number is a specific number stored in the specific number storage means at the time of incoming call, Is provided with an incoming call display means or incoming call ringing means for indicating incoming call information, and when the incoming call is an incoming call from the specific number, the incoming call display means or the incoming call ringing means is receiving an incoming call from other than the specific number Display a priority call by a display or ringing pattern corresponding to the specific number, and even when the priority call display is in progress, a predetermined key operation of the extension telephone can be used for an outside line or an extension line. Displays the incoming call information other than the specific number of the incoming call, when the inner wire phone was off-hook operation is characterized by responding to the incoming call corresponding to the call information in the display.

  The priority incoming call function according to the present invention is a telephone display that displays a caller's number, name, etc. from an incoming call with a higher priority when there are two or more incoming calls and the calling party's outgoing call number is lower in priority order. It is possible to make an incoming call with a predetermined ringing pattern or melody indicating the priority incoming call, and to visually and audibly confirm important incoming calls, and to have an advantage of being able to respond immediately to high priority incoming calls. .

  In addition, for incoming calls with low priority or general incoming calls, if the outside line key or extension key is pressed or a predetermined dial operation is performed, the called party number with a low priority or other than the priority incoming call is received. Can be displayed on the display of the telephone. As a result, it is possible to confirm another incoming party and respond first to an incoming call other than the party receiving the priority call.

  Further, by setting the presence / absence of a priority call for each extension telephone, an extension telephone that does not require a priority call can be used as usual.

  In addition, by setting up a telephone that applies priority calls for each priority call target specific number, in the case of a system that is used in multiple departments, it is possible to make a priority call only to the priority call target specific numbers required in each department. It becomes possible.

Further, the telephone-by-phone priority incoming call analysis processing means F38 is used when setting an extension telephone to which the priority incoming call is applied for each priority incoming call target specific number according to the third aspect of the invention, and the analysis result of the specific number analysis processing means F33. If the calling number matches the priority incoming call target identification number, it analyzes for each telephone whether the priority incoming call target identification number is a priority incoming call target and passes the presence / absence of the priority incoming call to the incoming call status display processing means F34.

The temporary storage means F39 has a function of temporarily storing the calling number information, the outside line state, the telephone state, etc. in the storage unit 16. The temporarily stored data is erased or changed by the information from the external line circuit control means F30, the incoming call status display processing means F34, and the reception analysis means F36 when the status of the external line or telephone changes.

The setting data storage means F40 includes a priority incoming call target specific number and a ringing pattern or melody of a priority incoming call, presence / absence of a priority incoming call for each telephone, a telephone to which a priority incoming call for each priority incoming target specific number is applied, time zone and day of the week And the like, and a function for storing other system operation data. When setting the priority incoming call target specific number for performing the incoming call priority, not only the presence / absence of the priority incoming call but also the priority order may be set. In addition, when setting the priority call target identification number for performing the above priority call, use the phone book group when registering the system phone book without directly registering the phone number, and specify the priority call target for each phone book group. It may be set as a number. Further, when setting a telephone to which a priority call for each priority call target specific number is set, it may be set for each extension group or tenant unit to which the telephone belongs, instead of the setting for each telephone. Furthermore, a condition for enabling the priority incoming call may be set for each telephone or group.

The system operation data stored in the setting data storage means F40 can usually be registered by a combination of operations such as the function key 28 and the dial key 26 of the key telephone 20, and the information sent from the key telephone 20 is received and analyzed.

In addition to the registration from the key telephone 20, the setting by the personal computer or the setting via the telephone line etc. remotely The registration means is not particularly limited.

In the case of the present invention, the system operation data stored in the setting data storage means F40 is used by the specific number analysis processing means F33 for collation with the data stored in the temporary storage means F39, or the second invention or the second invention. In the third invention, the telephone-based priority incoming call analysis processing means F38 is used as determination data for executing the priority incoming call. The data stored in the setting data storage means F40 is deleted or updated by a new setting instruction from the reception analysis means F36.

  Next, the flow of incoming call display processing on the key telephone main apparatus 10 side in the above embodiment will be described with reference to FIG. 1, FIG. 2, and FIG. When there is an incoming call on the outside line, a calling number reception process (S51) is executed, and the calling number information is stored in the storage unit 16 by the temporary storage means F39.

  When the calling number reception processing (S51) is completed, the specific number analysis processing means F33 determines whether the calling number information matches the priority call target specific number stored in the storage unit 16 by the setting data storage means F40 in advance. Collation is performed (S52).

If the collation result in step S52 does not match, the incoming call status display processing means F34 checks the telephone status stored in the storage unit 16 by the temporary storage means F39, and analyzes whether the incoming call is already being displayed (S53).

If the analysis result in step S53 is displaying an incoming call, the incoming call so far is continued, and the incoming call status display processing means does not transmit incoming call status information other than the external line lamp to the telephone (S54). On the other hand, if the result of the analysis in step S53 is not indicating that an incoming call is being displayed, the incoming call status display processing means F34 performs a new incoming call display start process for the telephone and transmits ringtone information, calling number information, etc. to the telephone 20. (S55).

If the collation result in step S52 is coincident, the incoming call state display processing means F34 checks the telephone state stored in the storage unit 16 by the temporary storage means F39, and analyzes whether the incoming call is already being displayed (S58).

If the priority call presence / absence can be set for each extension telephone according to the second aspect of the invention, the telephone-by-phone priority call analysis processing means F38 stores the storage unit by the setting data storage means F40 in advance before executing step S58. 16 confirms the presence / absence of a priority incoming call for each telephone stored in 16 and analyzes whether the priority incoming call is possible for each telephone (S56). If priority incoming is not possible, even if it is a priority incoming call target specific number, the process is equivalent to the priority incoming call target specific number mismatch in step S52, and the process proceeds to step S53. If priority incoming is possible, the process proceeds to step S58 (S57).

Further, when the setting of the telephone to which the priority call is applied for each priority call target specific number according to the third invention is possible, the telephone-by-phone priority call analysis processing means F38 performs the setting in advance before executing step S58. The priority incoming call application telephone for each priority call target specific number stored in the storage unit 16 by the data storage means F48 is confirmed, and it is analyzed whether the priority call is applied to the priority call target specific number (S56). In the case of a telephone to which priority call reception is not applied, even if it is a priority call target specific number, the processing is equivalent to the priority call target specific number mismatch in step S52, and the process proceeds to step S53. When the priority incoming call is applied, the process proceeds to step S58 (S57).

If the analysis result in step S58 is not indicating that an incoming call is being displayed, the incoming call status display processing means F34 performs a new incoming call display start process for the telephone and transmits ringtone information, calling number information, etc. to the telephone 20 (S59). ). On the other hand, when the incoming call is being displayed, the process proceeds to step S60.

In step S60, the incoming call status display processing means F34 analyzes whether or not the other party already displaying the incoming call is a priority incoming call target specific number. The processing means F34 does not transmit the incoming state information other than the external line lamp to the telephone (S61). In cases other than the priority incoming call target specific number, the incoming call status display processing means F34 temporarily stops the incoming call so far (S62), and the incoming call status display processing means F34 performs the incoming call display start processing of the priority incoming call target specific number for the telephone. Then, ringing tone information, calling number information, and the like are transmitted to the telephone 20 (S63).

When another telephone answers during the incoming call display or when the caller hangs up, the incoming line display stop processing for the outside line is performed (S64).

After the incoming call display stop process (S64), the transition control means F37 confirms the external line state stored in the storage unit 16 by the temporary storage means F39, and ends the process if there is no incoming external line. If there is an incoming line, the process returns to step S52, and the specific number analysis processing means F33 confirms whether the calling number information of the external line matches the priority call target specific number stored in advance by the setting data storage means F40. Perform verification.

  Next, the flow of the telephone response process on the key telephone main apparatus 10 side when the telephone side operates during the priority incoming call display in the above embodiment will be described with reference to FIG. 1, FIG. 2 and FIG. During the priority call, the calling number, name, etc. of the priority call target specific number are displayed on the display 29 of the key telephone 20 (S71).

If the telephone performs an off-hook operation in the state of step S71 (Yes in S72), an incoming call response process for the priority incoming call is executed (S73).

In the state of step S71, the telephone does not perform an off-hook operation (No in S72), and when another incoming call outside line key is pressed (S74), the key press information from the key telephone 20 is temporarily stored via the reception analysis means F36. It is stored in the storage unit 16 by F39. When the incoming call status display control means F34 confirms the storage unit 16 and determines that the telephone has pressed the incoming call outside line key (or may be a priority incoming call outside line key), the incoming call number information on the outside line is received. The transmission number is transmitted to the telephone 20, and the incoming call number, name, etc. are displayed on the pressed outside line key on the display 29 of the key telephone 20 (S75). In this embodiment, an example of pressing an outside line key is described as an example. However, when an extension key being received is pressed instead of an outside line key, it is possible to display the calling party number, name, etc. of the other party receiving the extension. Also good.

When the telephone performs an off-hook operation while displaying the incoming call number, name, etc. on the pressed outside line key (S76), an incoming line response process corresponding to the pressed outside line key is executed (S77).

It should be noted that the incoming call number, name, etc. displayed on the pressed outside line key continues for a certain period of time, and if no off-hook operation is performed during the display, the calling number, name, etc. of the priority incoming call target specific number in step S71 are displayed. Return to display.
