Description

  The present invention enables other people to confirm and grasp the communication status between a work instructor who performs a work instruction and a worker who performs the work by listening to the instruction using a telephone used in the office. The present invention relates to a mechanism for monitoring call voice.

  Currently, a cordless telephone system with a voice monitoring function has been proposed as a mechanism for monitoring telephone conversation voices used in offices. A conventional cordless telephone system with a voice monitor function includes a plurality of cordless telephones, a wired telephone, a speaker, and a private branch exchange. In the private branch exchange, a plurality of cordless telephones, wired telephones, and speakers are group-set as members of the conference call in advance. In this group setting, a telephone number is registered as a conference call number.

  For example, when a user of any cordless telephone enters a conference call telephone number and makes a call, the private branch exchange connects the voice line between all the telephones set in the group and activates the call. . Further, the private branch exchange controls the voice lines between all the telephones and the voice lines of the speakers so as to output the voice of the telephone calls between the telephones during the call from the speakers.

  Therefore, in the private branch exchange, the telephone set to be monitored for call voice needs to be registered in advance as a group setting.

  However, the usage of cordless telephones in offices has changed recently. For example, one cordless telephone is assigned to one person. In other words, depending on the time and place, it is assumed that a plurality of work instructors and a plurality of workers corresponding to work simultaneously have cordless telephones assigned to each person. Therefore, the number of combinations of work instructors and workers is enormous.

  Therefore, in such a conventional cordless telephone system with a voice monitor function, the task of registering the group setting in the private branch exchange becomes complicated. Therefore, there is a need for a mechanism that is used in a telephone system with a voice monitor function that monitors the voice of an arbitrary two-party call even if the user is not registered in the group settings as a conference call member in advance.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a private branch exchange that performs control so that call voice between a plurality of arbitrary telephones can be monitored by other devices.

  The private branch exchange according to the present invention outputs a voice between a line switching means for connecting a voice line between at least two telephones out of a plurality of telephones and a telephone during a call from a device other than the telephone during the call. A storage means for storing a number for permitting the connection, and when the number is input, the line connection so that a voice line of a device other than the telephone during the call is connected to a voice line between the telephone during the call Control means for controlling the means.

  According to the above-described invention, since the user does not need to determine a telephone to be monitored in advance, the telephone to be monitored can be freely selected. Furthermore, since the user does not need to register the telephone to be monitored in advance in the private branch exchange, the prior setting can be simplified.

The flowchart which shows the audio | voice monitor setting which concerns on 1st Embodiment. The flowchart which shows the audio | voice monitor setting which concerns on 2nd Embodiment.

  Hereinafter, this embodiment will be described with reference to the drawings. FIG. 1 is a block diagram of a telephone system with a voice monitor function according to the first embodiment. The telephone system with a voice monitor function is for monitoring a voice of an arbitrary two-party call mainly in an office.

  The telephone system with a voice monitor function includes a plurality of cordless telephones 10, 11, 12, a connection device 40, a private branch exchange 50, a wired telephone 60, and a speaker 70. The cordless telephone 10 is a wireless telephone used for calling with other telephones in the system. The same applies to the cordless telephones 11 and 12. The connection device 40 connects communication from the cordless telephones 10, 11, and 12 to the private branch exchange 50. The connection device 40 converts the communication format between the cordless telephones 10, 11, and 12 into a format that can be processed by the private branch exchange 50. The connection device 40 is always connected to the private branch exchange 50 in a communicable state. The private branch exchange 50 controls connection / disconnection of a voice line (call line) between telephones used in the system. The private branch exchange 50 includes a control unit 501, a line switching unit 502, a line connection unit 503, and a setting unit 504.

  The control unit 501 controls the operation of each unit in the private branch exchange 50. The line switching unit 502 activates the voice line that is the subject of the call in the system. The line connection unit 503 connects a voice line between the connection device 40, the wired telephone 60, the speaker 70, and the private branch exchange 50. The setting unit 504 stores the monitor number. A monitor number is registered in the setting unit 504 in advance. The monitor number is entered on a telephone other than the telephone being used to connect the voice line of another device in the system to the voice line between the telephones that are on the phone and to connect at least three voice lines. It is a number to be. The monitor number is arbitrarily variable, for example, by a person who has authority over the system. Here, for example, the monitor number 30 is registered in the setting unit 504.

  The wired telephone 60 is a wired telephone used for calling with other telephones in the system. The wired telephone 60 is connected to the private branch exchange 50. The speaker 70 outputs sound. The speaker 70 is connected to the private branch exchange 50. The speaker 70 is used to monitor call voice between a plurality of arbitrary telephones.

  Next, voice monitor setting in the private branch exchange 50 according to the first embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing audio monitor setting according to the first embodiment. Here, as an example, an example in which a call between the cordless telephone 10 and the cordless telephone 11 is monitored (output) by the speaker 70 will be described.

  First, the line switching unit 502 activates the voice line between the cordless telephone 10 and the cordless telephone 11. The line switching unit 502 connects a voice line between the cordless telephone 10 and the cordless telephone 11. Therefore, a call is in progress between the cordless telephone 10 and the cordless telephone 11. Here, the user of the cordless telephone 10 inputs a hold on the cordless telephone 10.

  Based on the hold input at the cordless telephone 10, the control unit 501 enters a reception state of telephone number information from the line connection unit 503 via the line switching unit 502 (step S 101). The control unit 501 determines whether or not the telephone number information input from the cordless telephone 10 is the same as the monitor number 30 registered in the setting unit 504 (step S102). When the telephone number information is not the same as the monitor number 30, or when the telephone number information is not input within a predetermined time (step S102, No), the control unit 501 transfers the hold based on the hold input on the cordless telephone 10 The operation is executed (step S103). In the hold transfer operation, for example, the control unit 501 sets the voice line between the cordless telephone 10 and the cordless telephone 12 to the valid state, and sets the voice line of the cordless telephone 10 to the invalid state. Is to control.

  When the monitor number 30 registered in advance in the private branch exchange 50 is input by the user on the cordless telephone 10 (step S102, Yes), the control unit 501 sends the cordless telephone 10 and the cordless telephone 11 to the circuit switching unit 502. An instruction is given to connect the audio line to the audio line of the monitor speaker 70 (step S104). That is, the line switching unit 502 activates the audio line of the monitor speaker 70.

  The line switching unit 502 connects the corresponding voice line (here, the voice line between the cordless telephone 10 and the cordless telephone 11) to the voice line of the speaker 70 (step S105). The speaker 70 outputs a call voice on a voice line between the cordless telephone 10 and the cordless telephone 11. That is, in this system, the speaker 70 enters a monitoring state of the call voice between the cordless telephone 10 and the cordless telephone 11 (step S106).

  Here, in step S105, the circuit switching unit 502 connects the voice line between the two-party telephones to the voice line of the speaker 70 in the same manner as a third-party call such as a three-party call, which is a known method. Can be implemented.

  According to the first embodiment, it is possible to output a call voice between arbitrary telephones from the speaker 70 by an operation from a cordless telephone during a call. Here, the monitor for call voice between cordless telephones has been described, but the same applies to the monitor for call voice between the cordless telephone 10 and the wired telephone 60. In this case, the user of the wired telephone 60 may input the monitor number 30 after inputting the hold on the wired telephone 60. Further, the case where the voice line between the two parties is connected to the voice line of the monitor speaker 70 for monitoring has been described, but the same applies to the case where the voice line between the three parties is monitored.

  Next, a second embodiment will be described. The system according to the second embodiment is the same as the system configuration described in the first embodiment shown in FIG. The second embodiment relates to a system for monitoring the call voice between the cordless telephone 10 and the cordless telephone 11 during a call with another telephone.

  Next, voice monitor setting in the private branch exchange 50 according to the second embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing voice monitor setting according to the second embodiment. Here, as an example, a description will be given of an example in which the voice of a call between the cordless telephone 10 and the cordless telephone 11 is monitored by the cordless telephone 12. In the setting unit 504, the monitor number 30 is registered as in the first embodiment. Here, the line switching unit 502 activates the voice line between the cordless telephone 10 and the cordless telephone 11. The line switching unit 502 connects a voice line between the cordless telephone 10 and the cordless telephone 11. Therefore, a call is in progress between the cordless telephone 10 and the cordless telephone 11.

  First, the control unit 501 enters a reception state of telephone number information from the line connection unit 503 via the line switching unit 502 based on the input of telephone number information at the cordless telephone 12 (step S201). Next, the control unit 501 determines whether the telephone number information received from the cordless telephone 12 is a telephone number with a monitor number (step S202).

  Here, the telephone number with the monitor number is a series of numeric strings in which the monitor number 30 is added to the telephone number assigned to the telephone that the user of the cordless telephone 12 wants to talk to. The control unit 501 determines whether the telephone number information received from the cordless telephone 12 is a telephone number with a monitor number based on an internal number plan. In the private branch exchange 50, number information is generally set so that telephone numbers and special numbers do not overlap. The number information is registered in the setting unit 504.

  Here, a case where the voice of a call between the cordless telephone 10 and the cordless telephone 11 is monitored by the cordless telephone 12 will be described. Accordingly, the user of the cordless telephone 12 makes a call to the cordless telephone 10. The user of the cordless telephone 12 may make a call to any one of a plurality of telephones that are the target of the call voice to be monitored.

  When the user of the cordless telephone 12 makes a call to the cordless telephone 10, the user inputs the monitor number after the telephone number assigned to the cordless telephone 10. In this example, the user of the cordless telephone 12 inputs the number 1030 on the coatless telephone 12.

  In this example, since the telephone number 10 is assigned to the cordless telephone 10, a series of numbers 1030 is a number that does not exist in the numbering plan because the first two digits overlap. Based on the number information registered in the setting unit 504, the control unit 501 determines that the number for simply calling the cordless telephone 10 with the cordless telephone 12 is not input. Therefore, the control unit 501 can determine that the numbers input on the cordless telephone 12 are consecutive numbers. That is, the control unit 501 recognizes that the number 30 in the subsequent stage has a different meaning because the number 10 in the previous stage is the number of the cordless telephone.

  When the monitor number is not assigned (that is, when only the number assigned to the telephone is input) (step S202, No), the control unit 501 is based on the telephone number information input by the cordless telephone 12. A transmission operation is executed (step S203). Therefore, the control unit 501 controls the line switching unit 502 so that the voice line between the telephone corresponding to the telephone number information input by the cordless telephone 12 and the cordless telephone 12 is enabled.

  When the monitor number is attached (step S202, Yes), the control unit 501 separates the telephone number information input from the cordless telephone 12 into the preceding telephone number and the subsequent monitoring number (step S204). In this example, the control unit 501 separates the preceding number 10 that is the telephone number assigned to the cordless telephone 10 and the subsequent number 30 that is the monitor number. Here, the subsequent number 30 matches the monitor number 30 registered in the setting unit 504. Therefore, the control unit 501 recognizes the subsequent number 30 as the monitor number 30 registered in the setting unit 504. Accordingly, the control unit 501 determines that the number 1030 input by the cordless telephone 12 means that the call voice of the cordless telephone 10 to which the telephone number 10 is assigned is monitored by the cordless telephone 12.

  The control unit 501 performs a call origination operation based on the preceding number 10 which is the telephone number assigned to the cordless telephone 10 separated from the telephone number information input by the cordless telephone 12 (step S205). That is, the control unit 501 controls each unit of the private branch exchange 50 so as to connect a voice line between the cordless telephone 10 and the cordless telephone 12.

  The control unit 501 instructs the line switching unit 502 to connect the voice line between the cordless telephone 10 and the cordless telephone 11 to the voice line (voice input line) of the cordless telephone 12 (step S206). That is, the circuit switching unit 502 activates the voice line of the cordless telephone 12 based on an instruction from the control unit. The circuit switching unit 502 connects the voice line between the cordless telephone 10 and the cordless telephone 11 to the voice line of the cordless telephone 12. The cordless telephone 12 outputs a call voice on a voice line between the cordless telephone 10 and the cordless telephone 11. In other words, in this system, the cordless telephone 12 is in a state where the call voice between the cordless telephone 10 and the cordless telephone 11 is monitored. Here, in step S206, the circuit switching unit 502 connects the voice line between the two-party telephones to the voice line of another cordless telephone in the same manner as the third-party call such as a three-party call which is a known method. It can carry out by the method of.

  According to the second embodiment, a call voice between any telephones can be output from another cordless telephone by an operation from another cordless telephone that is not used for the telephone call. Here, the monitor for call voice between cordless telephones has been described, but the same applies to the monitor for call voice between the cordless telephone 10 and the wired telephone 60. Furthermore, although the example in which the two-party call voice between arbitrary telephones is monitored by the cordless telephone 12 has been described, it may be monitored by the wired telephone 60. In this case, the user of the wired telephone 60 may input the telephone number information obtained by adding the monitor number 30 to the telephone number assigned to the telephone to be talked on the wired telephone 60. Further, the case where the voice line between the two parties is connected to the voice line of another cordless telephone for monitoring has been described, but the same applies to the case where the voice line between the three parties is monitored.

  According to the present embodiment, it is possible to monitor call voice between any two parties with a monitor speaker or other cordless telephone. Furthermore, according to the present embodiment, voice monitoring can be performed even in a situation where a combination of callers, that is, a combination of telephones in a call cannot be specified.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying constituent elements without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
