Abstract

PROBLEM TO BE SOLVED: To prevent an extension telephones 2 from ringing when there is an incoming call from a number which has not been set as incoming call rejection due to the inability to determine whether or not incoming call rejection should be set.SOLUTION: When a telephone exchange 1 receives an incoming call from a calling number A again (S11), the telephone exchange 1 determines whether or not the calling number A is on a blacklist or gray-list. If the calling number A is on the gray-list, the telephone exchange 1, for example, notifies all extension phones 2 of the calling number A and makes the phones receive the call without ringing (S12). In other words, the telephone exchange 1 notifies the extension telephones 2 of the calling number A and transmits a signal instructing the phones not to ring. This prevents all the extension phones 2 from ringing and allows all the extension phones 2 to display the calling number A (S13).

Description

  The present invention relates to a telephone exchange apparatus and a telephone which cannot prevent whether or not the call can be set to be rejected, and can prevent the extension telephone from ringing when a call with the calling party number which is not set to be rejected is received. The present invention relates to an operation method of a switching apparatus and a telephone system.

  Conventionally, as an example of a nuisance call incoming rejection method, there is one in which a calling number is registered in a black list and a white list (see Patent Document 1).

JP 2007-116542 A

  By the way, in order to reject incoming calls that are nuisance calls to extension telephones accommodated in private branch exchanges, such as corporate extension telephones, even if you do not set incoming call rejection on each extension telephone, If incoming call rejection is set in the private branch exchange, it is possible to reject all incoming calls that are nuisance calls.

  However, even if an incoming call with a certain calling number is annoying for some users, it may not be for other users, and the private telephone switching device simply rejects the calling number. Cannot be set.

  For example, if it is not possible to determine whether or not the calling number can be set to call rejection, and if the call is not set to call rejection, the extension telephone rings when a call with that calling number is received, which is It becomes annoying.

  The present invention has been made in view of the above-mentioned problems, and the purpose of the present invention is to determine whether or not the call rejection can be set, and the calling number that is not set to the call rejection is left. It is an object of the present invention to provide a telephone exchange device, an operation method of the telephone exchange device, and a telephone system that can prevent an extension telephone from ringing when an incoming call is received.

  In order to solve the above-described problems, the first aspect of the present invention is a telephone exchange device, and performs a ringing incoming notification with a calling number notification and a ringing instruction to an extension telephone accommodated in the telephone exchange device. An extension call unit, a list management unit that manages a gray list consisting of calling numbers of calls that should arrive at the telephone exchange and should be ring-free, and a call arrives at the telephone exchange If so, a calling number determination unit that determines whether or not the calling number of the call is on the greylist, and if the calling number is on the greylist, a ringing incoming call is made to the extension calling unit. And a non-ringing incoming call instruction unit for instructing.

  For example, the telephone exchange device registers a calling number of a call that should be made without ringing in the greylist and deletes a calling number of a call that should not be ringed from the greylist Is provided.

  For example, the calling number management unit registers the calling number of the received call in the gray list based on the status of response from the extension telephone to an incoming call not accompanied by a no ringing instruction.

  For example, the calling number management unit deletes the calling number of the call that has made a ringing incoming call from the gray list based on the response status from the extension telephone to the ringing incoming call.

  For example, the list management unit stores a black list including call origination numbers of calls to be rejected, and the call origination number determination unit determines that if the call arrives at the telephone exchange device, the call origination number of the call is the black list. It is determined whether the call is on the list, and if the calling number is on the black list, the call is rejected. The number of the call that should be registered in the greylist and the call that should not be ringed should be deleted from the greylist, and the number of the call that should be rejected should be registered in the blacklist and not rejected A calling number management unit for deleting a calling number from the black list, wherein the calling number management unit deletes the calling number to be registered in the black list from the gray list; It is registered in the rack list.

  For example, the calling number management unit deletes the calling number of a call that has made a ringing incoming call from the gray list and registers it in the black list based on the status of the response from the extension telephone to the ringing incoming call.

  For example, the calling number management unit deletes the calling number from the gray list when the number of times that the extension telephone does not respond to a ringing incoming call with the same calling number reaches a predetermined number of times, and Register in the blacklist.

  For example, the calling number management unit deletes the calling number from the gray list and registers it in the black list when a predetermined length of time has elapsed since the calling number was registered in the gray list.

  The second aspect of the present invention is a method of operating a telephone exchange device, wherein the telephone exchange device makes a ringing incoming call with a calling number notification and a ringing instruction to an extension telephone accommodated in the telephone switching device. An extension call unit capable of managing a gray list including a call origination number of a call that arrives at the telephone switching device and should be ring-free incoming, and the operation of the telephone switching device The method includes the step of the caller number determining unit of the telephone exchange device determining whether the caller's caller number is in the greylist when a call arrives at the telephone exchange device; And a step of instructing the extension calling unit to make a ringing incoming call if the calling number is in the gray list.

  A telephone system according to a third aspect of the present invention includes the telephone exchange device and an extension telephone accommodated in the telephone exchange device.

  According to the present invention, it is not possible to determine whether or not the call can be set to be rejected, and it is possible to prevent the extension telephone from ringing when a call with the calling party number that is not set to be rejected is received. .

It is a block diagram of the telephone system which concerns on this Embodiment. 4 is a sequence diagram showing an example of the operation of the telephone exchange device 1. FIG. 6 is a sequence diagram illustrating another example of the operation of the telephone exchange device 1. FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration diagram of a telephone system according to the present embodiment. The telephone system includes a private branch exchange apparatus (hereinafter referred to as a telephone exchange apparatus 1) 1 and a plurality of extension telephones 2 (only one is shown in the figure) accommodated in the telephone exchange apparatus 1. The extension telephone 2 displays the calling number and does not ring if there is an incoming call with a calling number notification and no ringing instruction (hereinafter referred to as no ringing incoming call) from the telephone exchange device 1 to the extension telephone 2. It is like that. On the other hand, the extension telephone 2 displays the calling number when there is an incoming call with a calling number notification and no ringing instruction (hereinafter referred to as a normal incoming call), and does or does not ring according to the setting for the extension telephone 2. It is like that.

  The telephone exchange device 1 includes an extension calling unit 11 for receiving a call arriving at the telephone exchange device 1 to the extension telephone 2 and a black list (calling number) of calls arriving at the telephone exchange device 1 that should be rejected. A list management unit 12 that manages a black list (hereinafter simply referred to as a black list) and a gray list (hereinafter simply referred to as a gray list) that includes call origination numbers to be sent to the extension telephone 2 and a black list and a gray list. When a call arrives at the telephone number management unit 13 for registering or deleting the calling number and the telephone exchange device 1, the list management unit 12 is inquired and the calling number of the call is in either the black list or the gray list. The calling number determination unit 14 for determining whether the call is received or not, the arrival time, the annihilation time, the calling number, the called number, the presence or absence of a response or incoming call rejection of all calls arriving at the telephone exchange device 1 When the communication history management unit 15 that collects and stores and the calling number determination unit 14 determine that the calling number is in the gray list, the extension calling unit 11 is instructed to make a silent call. And a ringing incoming call instruction unit 16.

  FIG. 2 is a sequence diagram showing an example of the operation of the telephone exchange device 1. For example, if a call arrives at the telephone exchange device 1 from a certain telephone (referred to as a partner telephone 3) (S1), the communication history management unit 15 stores the arrival time of the call, the calling number, and the like. Further, the calling number determination unit 14 determines whether the telephone number A of the other party telephone 3, that is, the calling number (called calling number A) is in the black list or the gray list. If the calling number determination unit 14 determines that the calling number A is not in either the black list or the gray list, the calling number determination unit 14 instructs the extension calling unit 11 to make a normal call and notifies the calling number A. Thereby, the extension calling unit 11 notifies the calling number A to all the extension telephones 2, for example, and makes a normal incoming call (S2). Thereby, for example, all the extension telephones 2 ring and the calling number A is displayed (S3).

  The communication history management unit 15 stores the presence / absence of a response to the normal incoming call. For example, when any of the extension telephones 2 responds to the normal incoming call and the call disappears after a call, the communication history managing unit 15 further stores the extinction time and the like. To do.

  The calling number management unit 13 registers the calling number A in the gray list if, for example, information indicating that there is no response to the calling number A and this normal call is obtained via the communication history management unit 15 (S4). .

  Thereafter, if the call with the calling number A arrives at the telephone exchange device 1 again (S11), the communication history management unit 15 similarly stores the arrival time of the call, the calling number, and the like. Further, the calling number determination unit 14 determines whether the calling number A is in the black list or the gray list. Here, the calling number determination unit 14 determines that the calling number A is in the gray list. Upon receiving this determination result, the ringing incoming call instructing unit 16 instructs the extension calling unit 11 to make a ringing incoming call and notifies the calling number A. Accordingly, the extension calling unit 11 notifies the calling number A to all the extension telephones 2, for example, and makes a ringing incoming call (S12). That is, the extension calling unit 11 notifies the extension telephone 2 of the calling number A and transmits a signal instructing no ringing. As a result, none of the extension telephones 2 ring, and all the extension telephones 2 display the calling number A (S13).

  In step S12, for example, the following method can be adopted by the interface between the telephone exchange device 1 and the extension telephone 2.

In the case of analog: The telephone exchange device 1 does not send a call signal (IR). Alternatively, the telephone exchange device 1 and the extension telephone 2 are provided with a 1300 Hz silent incoming call (used in a facsimile communication network) function.

In the case of ISDN: Q. A signal information element of the 931 SETUP message is installed, and a function that does not ring is received from the telephone exchange device 1 to the extension telephone 2 using the information element, and the extension telephone 2 that receives it receives a function.

In the case of VoIP: The telephone exchange device 1 and the extension telephone 2 are mounted with information (for example, a unique header) for instructing a silent call in the SIP INVITE message, and from the telephone exchange apparatus 1 to the extension telephone 2 A function that does not ring is provided to the extension telephone 2 that makes a ringing incoming call.

  Now, the communication history management unit 15 stores the presence / absence of a response to the silent incoming call. For example, if any of the extension telephones 2 responds to the silent incoming call and the call disappears after the call, the communication history management unit 15 further cancels the incoming call. Memorize time etc.

  The calling number management unit 13 uses the communication history management unit 15 to, for example, set a predetermined number of times (for example, 10 times) that the extension telephone 2 has not responded to a ringing incoming call with the calling number A. If the information indicating that it has been reached is acquired (condition 1 is satisfied), or if a predetermined length of time (for example, one month) has elapsed since the calling number A is registered in the greylist (condition 2 is satisfied), The calling number A is deleted from the gray list, and the calling number A is registered in the black list (S14). If either condition is satisfied, the calling number A may be deleted from the gray list, and the calling number A may be registered in the black list.

  Thereafter, if the call with the calling number A arrives at the telephone exchange device 1 again (S21), the communication history management unit 15 similarly stores the arrival time of the call, the calling number, and the like. Further, the calling number determination unit 14 determines whether the calling number A is in the black list or the gray list. Here, the calling number determination unit 14 determines that the calling number A is in the black list, and rejects (rejects the incoming call) the incoming call with the calling number A to the extension telephone 2 (S22). For example, the telephone exchange device 1 sends a guidance to the other party's telephone and extinguishes the call. The communication history management unit 15 stores the incoming call rejection and the time.

  Therefore, in this sequence example, an annoying situation where the extension telephone 2 rings can be prevented by the non-ring incoming call, and an annoying situation where the calling number is displayed can be prevented by rejecting the incoming call.

  FIG. 3 is a sequence diagram showing another example of the operation of the telephone exchange device 1. Here, it is assumed that the operations up to the non-ringing incoming call (S12) in FIG. 2 and the display of the calling number A (S13) are performed.

  For example, a user who has been waiting for an incoming call with calling number A cannot hear a ringing tone, but knows the incoming call by displaying the calling number, and makes the extension telephone 2 off-hook and respond (S15).

  Alternatively, the user dares to make the extension telephone 2 off-hook and respond so that the calling number is not registered in the black list, for example, even if there is no need for a call.

  That is, the ringing incoming call is also a mechanism for notifying that the calling number is in a stage before being registered in the black list and inquiring whether or not the calling number may be registered in the black list.

  The communication history management unit 15 stores that there is a response to the ringing incoming call, and further stores the annihilation time when the call ceases after the call.

  The calling number management unit 13 deletes the calling number A from the gray list when it acquires information indicating that there is a response to the calling number A and the ringing incoming call via the communication history management unit 15 (S16).

  Thereafter, if the call with the calling number A arrives at the telephone exchange device 1 again (S31), the communication history management unit 15 similarly stores the arrival time of the call, the calling number, and the like. Further, the calling number determination unit 14 determines whether the calling number A is in the black list or the gray list. Since the calling number A is not in either the black list or the gray list, the calling number determination unit 14 instructs the extension calling unit 11 to make a normal call and notifies the calling number A. Thereby, the extension calling unit 11 notifies the calling number A to all the extension telephones 2, for example, and makes a normal call (S32). Thereby, all the extension telephones 2 ring and the calling number A is displayed (S33).

  Therefore, in this example of the sequence, the user who has been waiting for the call of the calling party number A can hear the ringing sound in addition to being able to see the calling party number. That is, it is possible to regain the convenience for such a user who has been lost by registering the calling number in the gray list.

  If there is a user who feels that an incoming call with the calling number A is annoying, the extension telephone 2 of the user may be set to ignore the incoming call with the calling number A.

  In addition, although the registration and deletion of the calling number in the black list and the gray list are automatically performed, the list may be displayed on a display or the like, and the registration and deletion may be performed manually via an input device such as a keyboard. Further, registration and deletion may be performed by communication via a network.

  Incoming calls are made to all the extension telephones 2. However, for example, an incoming call may be made only to the extension telephone 2 of the called number designated by the call.

  Therefore, according to the present embodiment, if the calling party number is on the gray list, it is not possible to determine whether or not to reject the incoming call by performing a ringing incoming call, and the incoming call rejection is not set. Thus, it is possible to prevent the extension telephone 2 from ringing and causing trouble, for example. Further, since the extension telephone 2 does not ring, a user who does not want to respond or a user who does not know the calling number can easily ignore the incoming call (no ringing incoming call). On the other hand, since the calling number is displayed, the user who wants to respond can respond.

  Further, the trouble of individually setting the non-ringing incoming call to the extension telephone 2 does not occur. Also, by registering the calling number in the gray list, it is possible to prevent erroneous registration in the black list.

  The computer program for causing the computer to function as the telephone exchange device 1 according to the present embodiment can be recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, or a magnetic tape. It can be widely distributed by being transmitted through a communication network such as the Internet.
