JP4056463B2 - Registration and deletion method of outgoing call restriction telephone number in key telephone - Google Patents

Description

  The present invention relates to a method for registering and deleting a call restriction telephone number in a key telephone, and in particular, includes a plurality of telephone lines, a plurality of dedicated telephones (multifunctional telephones) and a main apparatus that accommodates general telephones, and the telephones. The present invention relates to a registration method and a deletion method of a call restriction telephone number for performing registration and deletion of a call destination telephone number that is a target of call restriction in a key telephone.

  Conventionally, main telephones that accommodate multiple telephone lines, multiple dedicated telephones (multifunction telephones) and general telephones, and key telephones that consist of such telephones are used for telephone research based on customer lists. Widely used. Here, a plurality of telecommunicators may call the same customer, which may result in complaints from the customer or stress on the telecommunicator.

  If CTI (Computer Telephony Integration) is used to deal with such problems, customer information is stored in a database in advance in the computer, and the telephone number of the customer who made the call is notified to the computer from the key telephone. By displaying the telephone number, the plurality of telecommunicators can inform which customer has called. However, the CTI in which the computer and the key telephone are linked with each other increases the price of the system.

  By the way, for example, in order to control which outgoing calls can be made only within the city, or within the city and outside the city, the outgoing call control is controlled based on the telephone number (incoming call number) of the caller supplied from the telephone line. An electronic private branch exchange is known (see, for example, Patent Document 1). In the electronic private branch exchange apparatus described in Patent Document 1, the telephone number of the calling party is received, the received incoming call number is compared with the previously registered subscriber number, and both telephone numbers match. In this configuration, dialing from the caller is restricted based on the outgoing service restriction set corresponding to the registered subscriber number.

  Therefore, the above-mentioned method for restricting outgoing calls by the electronic telephone switching device is also applied to key telephones, and registration is performed by registering telephone numbers that are generally provided in key telephones and that are desired to restrict outgoing calls in the database of the system. It is conceivable to use an outgoing call restriction function that cannot make outgoing calls to the other party of the telephone number.

  However, conventionally, in a key telephone, registration and deletion of a destination telephone number that is a target of outgoing restriction can be performed only by a system administrator determined in advance by an installation contractor or a user.

  The present invention has been made in view of the above points, and it is possible to easily register a destination telephone number that is subject to outgoing restriction without being aware of the operation by the user. It is an object of the present invention to provide a method of registering and deleting a call restriction telephone number in a key telephone that can be automatically deleted.

  In order to achieve the above object, a first invention is a method of registering a call restriction telephone number in a key telephone comprising a main apparatus and a plurality of multi-function telephones accommodated in the main apparatus, the plurality of multi-function telephones The first step of dialing the destination telephone number using any of the multi-function telephones, and the telephone number matching the destination telephone number dialed in the first step is a destination telephone subject to outgoing call regulation When it is determined that there is a telephone number that matches in the second step and the second step for determining whether the number is registered in the database in which the number is registered, the outside line is released and used in the first step When it is determined in the second step that there is no matching telephone number in the third step of setting any multifunctional telephone to the standby state, the telephone number of the dialed destination telephone number is A fourth step of setting a speech path, a fifth step of determining whether or not a response signal indicating that the telephone having the destination telephone number has responded has been received from the central office after setting the speech path, and receiving the response signal And a sixth step of registering the answering destination telephone number in the database when the handset of any multifunction telephone is on-hooked.

  In the present invention, when the telephone number that matches the destination telephone number dialed from the multi-function telephone is not registered in the destination telephone number registration database subject to outgoing restrictions, the telephone of the destination telephone number responds. After receiving the response signal via the central office switch, when the on-hook of the calling multifunction telephone is detected, the dialed destination telephone number can be automatically registered in the database.

  In order to achieve the above object, a second invention is a method for registering a call restriction telephone number in a key telephone comprising a main apparatus and a plurality of multi-function telephones accommodated by the main apparatus. A first step of dialing a destination telephone number using an arbitrary multi-function telephone among functional telephones, and a telephone number that matches the destination telephone number dialed in the first step is an outgoing call subject to outgoing call restriction. When it is determined that there is a telephone number that matches in the second step and the second step for determining whether or not the destination telephone number is registered in the database, the outside line is released and the first step is performed. When it is determined that there is no telephone number that matches in the third step and the second step in which any multifunctional telephone used is in a standby state, the telephone of the destination telephone number dialed A fourth step of setting a communication path with the fifth step, a fifth step of determining whether or not a response signal indicating that the telephone having the destination telephone number has responded has been received from the central office after the communication path has been set, and a response signal After the registration cancel button is pressed, the sixth step of determining whether the handset of any multifunction telephone is on-hook, and the handset of any multifunction telephone without pressing the registration cancel button When it is determined that the handset of the answering machine is on-hooked, the seventh step of registering the answering destination telephone number in the database and after pressing the registration cancel button and determining that the handset of any multifunction telephone is on-hooked Without waiting for registration of the answering destination telephone number in the database, the outside line is released and any multifunctional telephone used in the first step is put on standby. Characterized in that it comprises an eighth step of the.

  In the present invention, when the telephone number that matches the destination telephone number dialed from the multi-function telephone is not registered in the destination telephone number registration database subject to outgoing restriction, a response signal from the telephone of the destination telephone number is sent. After receiving it via the central office switch, when it is detected that the multi-function telephone of the caller is on-hook by pressing the registration cancel button, the outside line is released without registering the dialed call destination telephone number in the above database. Then, it is possible to register the destination telephone number dialed only when on-hook without pressing the registration cancel button in the database.

  In order to achieve the above object, the third invention is that the registration cancel button in the second invention is not pressed when a call with the desired destination of the answering destination telephone number is established, It is characterized in that it is pressed when a call with is not established. In the present invention, for example, when the desired call partner is absent and the call cannot be made with the desired call partner or when there is a response from the answering machine and the call cannot be made with the desired call partner, the registration cancel button is pressed. Therefore, when it is not possible to make a call with a desired call partner, it is possible not to register the destination telephone number in the database.

  In order to achieve the above object, when the fourth invention determines that there is a telephone number that matches the third step in the first invention or the second invention in the second step, it is an outside line. After the release, the arbitrary multifunction telephone set used in the first step performs at least one of an alarm sound and an alarm display, and then the arbitrary multifunction telephone is set in a standby state. In the present invention, when a telephone number that matches a destination telephone number dialed from a multi-function telephone is registered in the destination telephone number registration database subject to outgoing restriction, outgoing calls to the dialed destination telephone number are restricted. In addition, it is possible to notify the user of the source multifunction telephone by performing at least one of an alarm sound and an alarm display.

In order to achieve the above object, the fifth invention comprises a main device and a plurality of multi-function telephones accommodated in the main device, and the main device includes the outgoing call regulation of the first invention or the second invention. a database destination telephone number as a target of transmission regulation registered by the telephone number registration process is stored in association with the registration date, call restriction telephone number of the key telephone having at least a clock section for clocking the current time A deletion method, which is registered in the database at a first step for determining whether or not the current time of the clock unit has reached a predetermined time, and when it is determined at the first step that the predetermined time has been reached. A second step of determining whether or not there is a destination telephone number that has passed an arbitrary set number of days from the registration date among the destination telephone numbers, and an arbitrary set number of days from the registration date in the second step The destination telephone number is determined to spent, characterized in that it comprises a third step of deleting from the database.

  In this invention, it is determined that an arbitrary set number of days has elapsed from the registration date among the destination phone numbers registered in the database in which the destination phone number subject to outgoing call regulation is stored in association with the registration date and time. Called phone numbers can be automatically deleted from the database.

  In order to achieve the above object, in the sixth invention, the second step of the fifth invention is replaced with a determination as to whether or not an arbitrary set number of days has elapsed, and the outgoing call registered in the database. The step of determining whether or not the number of destination telephone numbers exceeds a predetermined number, and when the third step is determined to exceed the predetermined number in the second step, the destination telephone number of the oldest registration date is determined. It is characterized by the step of deleting from the database.

  According to the registration method of the present invention, when the telephone number that matches the destination telephone number dialed from the multi-function telephone is not registered in the destination telephone number registration database subject to outgoing restriction, the dialed destination telephone number Are automatically registered in the above database, so that users of multi-function phones (for example, telecommunicators) do not need to perform operations for registering the destination telephone number and concentrate on their work. In addition, there is no need for the installation system administrator or user to register the telephone number of the callee in advance, and if a key telephone is used for research, etc., outgoing calls to the same customer can be restricted. Therefore, the complaint from the customer by duplicate transmission can be reduced.

  Further, according to the registration method of the present invention, even when the telephone number that matches the destination telephone number dialed from the multi-function telephone is not registered in the destination telephone number registration database subject to outgoing restriction, After receiving a response signal from the telephone of the destination telephone number via the central office switch, if it is detected that the multi-function telephone of the source is on-hook by pressing the registration cancel button, the dialed destination telephone number is Since the outside line is released without registering in the above database, the user of the multi-function telephone can arbitrarily decide whether or not to register in the database of the dialed destination telephone number. Even if the other party of the destination phone number answers, if you cannot talk to the desired party (individual), press the registration cancel button If the, even though could not talk to a desired communication partner, by the destination telephone number of the desired other party is registered in the database, it is possible to avoid the phenomenon that the call restriction.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an example of a key telephone system to which the method of the present invention is applied. In the figure, the key telephone is composed of a main device 10 and n (n is an integer of 2 or more) multi-function telephones 21 to 2n having a plurality of function buttons used by the telecommunicator. Further, the main apparatus 10 includes an office line interface unit 11 for making and receiving calls, an extension interface unit 13 for accommodating the multi-function telephones 21 to 2n, a communication path switch 12 for exchanging voice data, and the entire key telephone. A control unit 14 for controlling the function, a restriction telephone number database 15 for registering restriction telephone numbers subject to outgoing restriction, and a multifunction telephone for recording function assignment information of function buttons of the multifunction telephones 21 to 2n It comprises a button information database 16 and a clock unit 17 having a calendar / clock function.

  Among these, the regulated telephone number database 15 is constituted by, for example, a random access memory (RAM), and as shown in FIG. 2, the registered year and month and the regulated telephone number are registered in association with each other. Has been. As shown in FIG. 3, each of the multi-function telephones 21 to 2n has a telephone set (handset) 202 for transmission / reception and a function button 203 capable of setting various functions in a casing 201 which is a telephone body. And a dial button 204 for dialing the outgoing dial or the destination telephone number, and a display 205 for displaying character information at the time of outgoing restriction. The office line interface unit 11 is connected to m number of destination telephones 31 to 3m (m is a natural number) via the public network 41.

  With such a key telephone, it is possible to make a call from any multifunction telephone among the multifunction telephones 21 to 2n using any telephone line and to receive a call from an external destination telephone. In addition, basic functions such as enabling extension calls between the multi-function telephones 21 to 2n, holding a call between an external telephone and the multi-function telephone, and transferring the held call to another multi-function telephone. Have

  Next, the operation of the present embodiment will be described. FIG. 4 shows a flowchart of an embodiment of a method for registering a call restriction telephone number in a key telephone according to the present invention. Key telephones are widely used for operations such as telephone research based on customer lists. FIG. 4 shows an example in which a telecommunicator for such work makes a call based on a customer list.

  First, when the telecommunicator raises the handset (202 in FIG. 3) of any multifunction telephone among the multifunction telephones 21 to 2n (step S1 in FIG. 4), the control unit 14 causes the multifunction telephone (for example, , 21) is detected, the office line interface unit 11 is controlled, and a free outside line is captured (step S2 in FIG. 4). After the off-hook, when the telecommunicator dials the destination telephone number based on the customer list (step S3 in FIG. 4), the control unit 14 refers to the regulated telephone number database 15 (step S4 in FIG. 4), It is determined whether there is a regulated telephone number that matches the telephone number (step S5 in FIG. 4).

  When the regulated telephone number that matches the destination telephone number is not registered in the regulated telephone number database 15, the control unit 14 sends the dialed destination telephone number to the public network 41 via the office line interface unit 11. (Step S10 in FIG. 4). If the destination telephone number is that of the destination telephone 31, the destination telephone 31 responds (step S 11 in FIG. 4), and a response is received from a central office switch such as Nippon Telegraph and Telephone Corporation (NTT) in the public network 41. A signal is transmitted, and this response signal is received by the office line interface unit 11 (step S12 in FIG. 4).

  When the office line interface unit 11 receives the response signal, it notifies the control unit 14 of the information. Therefore, the control unit 14 controls the communication path switch 12 based on the response signal reception notification, and the number of external lines and telecommunicators is increased. A function telephone 21 is connected to form a communication path. Here, even when the other party cannot talk to the person due to absence, or when the answering machine responds, a response signal is sent from the office switch such as NTT. In this case, since research or the like cannot be performed, once a telephone number is registered in the regulated telephone number database 15, it becomes impossible to make a call again.

  Therefore, in the present embodiment, the control unit 14 notifies the extension interface unit 13 of the flashing control of the “registration cancel button” to the multifunction telephone (for example, 21 in FIG. 1) used by the telecommunicator. To do. As a result, the light emitting diode (LED) of the “registration cancel button” of the multi-function telephone 21 used by the telecommunicator blinks, and the control unit 14 determines whether or not the “registration cancel button” has been pressed (FIG. 4 step S14).

  When the telecommunicator finishes the research and on-hooks the handset 202 without pressing the “registration cancel button”, the control unit 14 stores the dialed destination telephone number and the clock unit 17 in the restricted telephone number database 15. The current year / month / day / hour / minute is automatically registered in association with the calendar / clock information (step S15 in FIG. 4). Further, the control unit 14 performs a process of releasing the used external line on the office line interface unit 11 (step S16 in FIG. 4), notifies the extension interface unit 13 and uses the multiline used by the telecommunicator. The function telephone 21 is set in a standby state (step S9 in FIG. 4).

  On the other hand, if the telecommunicator cannot be researched (for example, when a call with the desired destination is not established, or when the answering machine function of the destination telephone is activated), it flashes After pressing the “registration cancel button”, the handset 202 is hooked on-hook. As a result, the control unit 14 performs the process of releasing the used external line to the local line interface unit 11 without performing the registration operation in the regulated telephone number database 15 in step S15 (step S16 in FIG. 4). Then, the extension interface unit 13 is notified and the multi-function telephone 21 used by the telecommunicator is put into a standby state (step S9 in FIG. 4).

  On the other hand, if the control unit 14 determines in step S5 that there is a match among the regulated telephone numbers registered in the regulated telephone number database 15 in the step S5, the control unit 14 After performing release control on the outside line (step S6 in FIG. 4), control is performed to send an alarm sound from the speaker of the multi-function telephone 21 to the extension interface unit 13 (step S7 in FIG. 4). Display control such as “registration number transmission restriction” is controlled on the display 205 of the telephone 21 (step S8 in FIG. 4). Thereafter, the control unit 14 notifies the extension interface unit 13 to put the multifunction telephone 21 used by the telecommunicator into a standby state (step S9 in FIG. 4).

  As described above, according to the present embodiment, the telephone number for which the research has been performed is automatically registered without the need for the telecommunicator to perform the registration operation. There is no need for the operator or system administrator to register the telephone number of the caller, and the telecommunicator can concentrate on the business. In addition, the administrator or the like of the user does not need to register the destination telephone number, and can restrict the transmission of the registered destination telephone number. For this reason, it is no longer necessary to make calls from a plurality of telecommunicators to the same customer (destination telephone number), and complaints from customers can be reduced. Further, even when a response signal is received, if the research with the desired partner cannot be performed, the registration telephone number is automatically registered in the regulated telephone number database 15 by pressing the “registration cancel button”. Can be avoided, and subsequent outgoing restrictions can be avoided.

  Next, an embodiment of a method for deleting outgoing call restriction telephone numbers according to the present invention will be described. FIG. 5 shows a flowchart of an embodiment of a method for deleting outgoing call restriction telephone numbers according to the present invention. Here, if a destination telephone number is registered in the restricted telephone number database 15 every time a call is made, the storage capacity of the restricted telephone number database 15 is limited, so that it will overflow someday. I can no longer register.

  Therefore, in this embodiment, in order to prevent this problem, the destination telephone number registered according to the flowchart of FIG. 5 is automatically deleted (erased). That is, when the clock unit 17 has passed 0:00, the control unit 14 compares the registered year / month / day / hours in the restricted telephone number database 15 with the current time (step S21 in FIG. 5), and the set number of days. (Step S22 in FIG. 5), and if there are those that have passed the set number of days, the destination telephone number corresponding to the registered date and time that has passed the set number of days is regulated. It deletes from the telephone number database 15 (step S23 of FIG. 5).

  For example, it is assumed that telephone number A is registered in the regulated telephone number database 15 at 13:10 on September 1, 2003. When the clock unit 17 is changed from 23:59 on September 1, 2003 to 0:00 on September 2, 2003, the control unit 14 refers to the regulated telephone number database 15 and the telephone number A is “1 day. Judgment is made. The number of days to be deleted can be set to any number of days. For example, if “20 days” is set, the telephone number A is automatically retrieved from the regulated telephone number database 15 at 0:00 on September 21. Deleted.

  The present invention is not limited to the above embodiment. For example, in FIG. 4, when the registered restricted telephone number and the destination telephone number match, an alarm sound and an alarm display are displayed to indicate outgoing restriction. Although both are performed, only one of them may be performed. Further, in FIG. 5, the destination telephone numbers that have exceeded the set number of days at the predetermined time are deleted, but a predetermined number of predetermined destination telephone numbers are registered. 5 may be performed for the first time. Alternatively, the upper limit number of destination telephone numbers that can be registered may be determined in advance, and the destination telephone number with the oldest registration date and time may be deleted after reaching the upper limit number. Further, the set days can be arbitrarily changed by the user.

It is a system configuration diagram of an example of a key telephone system to which the method of the present invention is applied. It is an example of a structure of the control telephone number database in FIG. FIG. 2 is an external appearance explanatory view of an example of a multifunction telephone in FIG. 1.
