A start signal is output) (S67).

  When the activation instruction (S67) of the paging circuit 17 is completed, the transition control means F47 sends the tone sending unit 15 and the output side call path to the outside line of the outside line circuit 13 to the call path in order to send the opening sound at the start of the voice call. The communication path control means F44 is instructed to connect by the switch 12, and the communication path control means F44 is instructed to connect the tone transmission unit 15 and the paging circuit 17 by the communication path switch 12 (S68).

  In consideration of the case where the voice call cannot be answered, a process for terminating the voice call in a certain time may be performed. In this embodiment, after the call path is connected in step S68, the voice callable time timer process is started (S69). The voice callable time timer process will be described separately with reference to FIG.

  When the connection of the tone sending unit 15 to the communication path (S68) is completed, the transition control means F47 starts the voice call start sound (for example, “Puppu”, “Ping-pong pampong”, etc.) to the tone sending control means F42. The opening sound can be heard by the caller on the outside line side and the timing to start speaking can be grasped, and at the same time, the opening sound can be heard from the speaker of the broadcasting device 30 and also to the side answering the call. The user can be alerted to a voice call (S70).

  When the caller starts speaking, the caller's voice is transmitted from the speaker of the broadcasting device 30. When the responding person takes the extension at the nearest key telephone 20 (operation such as off-hook or extension button pressing), the extension The extension acquisition state of the key telephone 20 is stored in the storage unit 19 via the circuit 18, the data transmission / reception means F46, the reception analysis means F51, and the temporary storage means F53 (S71), and the voice call response special number waiting state from the key telephone 20 It becomes.

  Subsequently, when the voice call response special number is dialed by the key telephone 20 that has acquired the extension, the dial information is stored in the storage unit 19 via the extension circuit 18, data transmission / reception means F46, reception analysis means F51, and temporary storage means F53. (S72) The voice call response analysis processing means F52 collates with the voice call response special number stored in the storage unit 19 in advance by the setting data storage means F54 (S73).

  If the dial information of the key telephone 20 is a voice call response special number in step S73, the voice call response analysis processing means F52 notifies the transition control means F47 of the analysis result that it is a voice call response, and the transition control means F47 The communication path control means F44 is instructed to connect the bidirectional communication path of the external line circuit 13 and the bidirectional communication path of the extension circuit 18 connected to the key telephone 20 by the communication path switch 12, and in step S66. The communication path control means F44 is instructed to release the paging circuit 17 connected to the outside line circuit 13 from the communication path switch 12, and the voice call response analysis processing means F52 further analyzes the analysis result of the voice call response as a voice call. The control means F48 is notified, and the voice call control means F48 notifies the paging control means F45 of the end of the voice call. Ri, transitions to the call state of the external circuit and the response telephone only, the processing of the paging voice call is terminated (S74).

  If the dial information of the key telephone 20 is not a voice call response special number in step S73, other processing is performed (S75). For example, in the case of an extension number instead of a special number, the outgoing call processing to the corresponding extension number is performed. Note that there are a plurality of telephones that respond to the paging voice call, and steps S71 to S73 are executed for the plurality of telephones, so the paging voice call processing is not completed at this point.

  If the PB signal data is not a paging voice call special number in step S65, it is checked in step S76 if it is a simultaneous voice call special number. In the case of the group voice call special number, the target for voice call is limited to only the key telephones in the group, not the all-button telephones. is doing. If the PB signal data is a general voice call special number (or group voice call special number) in step S76, the dial information analysis processing means F50 sends an analysis result indicating that it is a general voice call (or group voice call) to the transition control means F47. The transfer control means F47 notifies the telephone line on the output side to the telephone of the extension circuit 18 connected to all the button telephones (or the button telephones in the empty group) 20 that are available for voice call, and the external line of the external circuit 13 The voice path sending means 14 and the PB signal receiving section 16 that have been connected to the outside line circuit 13 so far are instructed to the voice path control means F44 to connect to the input side voice path from the voice path switch 12. The communication path control means F44 is instructed to release from the communication path switch 12 (S77).

  Further, the dial information analysis processing means F50 notifies the voice call control means F48 of the analysis result that it is a simultaneous voice call (or group voice call), and the voice call control means F48 passes through the data transmission / reception means F46 and the extension circuit 18. A command to shift to the speaker calling state is given to all the button telephones in the idle state (or the button telephones in the empty group) 20 (S78). Although not shown, the voice call control means F48 confirms the voice call availability setting for each telephone stored in the storage unit 19 in advance by the setting data storage means F54 before executing step S77, so that the voice call is possible. The transfer control means F47 is notified to connect the speech path only to the correct telephone, and the data transmission / reception means F46 is instructed to shift only the telephone capable of voice calling to the speaker calling state.

  When an instruction to shift to the speaker call state (S78) is completed for all the button telephones (or button telephones in an empty group) 20 that are available for voice call in order to send out the initial sound at the start of the voice call The transition control means F47 instructs the speech path control means F44 to connect the tone transmission section 15 and the output side speech path to the external line of the external line circuit 13 by the speech path switch 12, and the tone transmission section 15 and the above-mentioned Instructs the communication path control means F44 to connect the output side communication path to the telephone of the extension circuit 18 connected to the all-button telephone (or group telephone) 20 that can be called by the communication path switch 12. (S79).

  In consideration of the case where the voice call cannot be answered, a process for terminating the voice call in a certain time may be performed. In this embodiment, after the call path is connected in step S79, the voice callable time timer process is started (S80). The voice callable time timer process will be described separately with reference to FIG.

  When the connection of the tone sending unit 15 to the communication path (S79) is completed, the transition control means F47 starts the voice calling start sound (for example, “Puppu”, “Ping-pong pampong”, etc.) to the tone sending control means F42. Can be heard, the beginning sound can be heard by the caller on the outside line, and the timing to start speaking can be grasped, and at the same time, the speaker 25 of the all-button telephone (or group telephone) 20 capable of voice call. Can hear the opening sound, and can alert the side responding to the call to a voice call (S81).

  When the caller starts speaking, the caller's voice is transmitted from the speaker 25 of the all-button telephone (or group telephone) 20 capable of voice call, and the responding person is the nearest button telephone (other telephone). Off-hook), the off-hook state of the key telephone 20-1 is stored in the storage unit 19 via the extension circuit 18, data transmission / reception means F46, reception analysis means F51, and temporary storage means F53. (S82).

  After receiving the off-hook information (S82), the voice call response analysis processing means F52 receives off-hook response availability data for the simultaneous voice call (or group voice call) for each telephone set in the storage unit 19 in advance by the setting data storage means F51. Confirm (S83), and notify the transfer control means F47 of the confirmation result. When the key telephone 20-1 off-hooked in step S82 can respond off-hook, the transition control means F47 determines the two-way communication path of the external circuit 13 and the two-way communication path of the extension circuit 18 connected to the button telephone 20-1. The communication path control means F44 is instructed to connect by the communication path switch 12, and the extension circuit 18 of the key telephone 20 other than the button telephone 20-1 connected to the external circuit 13 in step S77 is connected to the communication path switch 12. The voice call response analysis processing means F52 notifies the voice call control means F48 of the analysis result that it is a voice call response, and the voice call control means F48 All button telephones (or button telephones in a group) that have made a voice call via the transmitting / receiving means F46 and the extension circuit 18 By performing the notification of a voice call completed for 20, transitions to the call state with the external line circuit response phones only, the process of simultaneous voice calls (or group voice calls) is completed (S74).

  On the other hand, when the key telephone 20-1 off-hooked in step S82 cannot make an off-hook response to the simultaneous voice call (or group voice call) (S83), it enters a voice call response special number waiting state.

  Subsequently, when the voice call response special number is dialed by the off-hook key telephone 20-1, the dial information is stored in the storage unit 19 via the extension circuit 18, the data transmission / reception means F46, the reception analysis means F51, and the temporary storage means F53 ( S72), the voice call response analysis processing means F52 collates with the voice call response special number stored in the storage unit 19 in advance by the setting data storage means F54 (S73).

  If the dial information of the key telephone 20-1 is a voice call response special number in step S73, the voice call response analysis processing means F52 notifies the transition control means F47 of the analysis result that it is a voice call response, and the transition control means. F47 instructs the communication path control means F44 to connect the bidirectional communication path of the external line circuit 13 and the bidirectional communication path of the extension circuit 18 connected to the key telephone 20-1 with the communication path switch 12. In step S77, the communication path control means F44 is instructed to release the extension circuit 18 of the key telephone other than the key telephone 20-1 connected to the external line circuit 13 from the communication path switch 12, and further the voice call response analysis process The means F52 notifies the voice call control means F48 of the analysis result that it is a voice call response, and the voice call control means F48 sends the data transmission / reception means F48. 6. By notifying the end of the voice call to all the button telephones (or the key telephones in the group) 20 that have been making a voice call via the extension circuit 18, a transition is made to the call state of only the external line circuit and the answering telephone. Then, the simultaneous voice call (or group voice call) process ends (S74).

  If the PB signal data is not a general voice call special number (or group voice call special number) in step S76, it is checked in step S84 whether it corresponds to another special number or the like. If there is a corresponding special number, other processing is performed (S87). For example, when an extension number is used instead of a special number, the corresponding extension is called as a general DID method. Further, the transition control means F47 instructs the speech path control means F44 to release the voice guidance transmission section 14 and the PB signal reception section 16 that have been connected to the outside line circuit 13 from the speech path switch 12.

  If there is no corresponding special number or the like in step S84, the dial information analysis processing means F50 notifies the transition control means F47 of the analysis result (no corresponding special number or the like), and the transition control means F47 determines whether the tone sending unit 15 and the external line circuit 13 The communication path control means F44 is instructed to connect the output side communication path to the outside line by the communication path switch 12 (S85).

  When the connection of the tone sending unit 15 to the communication path (S85) is completed, the transition control unit F47 instructs the tone sending control unit F42 to send an error sound (which may be a busy tone, the same applies hereinafter), and the tone sending unit. 15 sends an error sound to the external line circuit 13 (S86). The error sound sending time of the tone sending unit 15 is set to a fixed time (can be changed by setting), and after sending the error sound, the transition control means F47 asks the speech path control means F44 to release the tone sending part 15 from the external line circuit 13. Instruct. Instead of the error sound from the tone sending unit 15, the error voice guidance from the voice guidance sending unit 14 may be sent.

  When the transmission of the error sound (S86) is completed, the process returns to the voice guidance transmission process (S63), and the voice guidance transmission process (S63) to the caller and the PB signal reception process (S64) are performed again. Although not clearly shown in the figure, the error processing from step S84 to step S86 is not repeated infinitely, but if a counter is provided and repeated a certain number of times (variable by setting), the outside line is output after a busy tone is emitted on the outside line side. , Disconnecting the outside line by playing a voice guidance indicating that the operation is invalid, or performing a transition to a normal incoming call.

  The flow when the caller side ends is not clearly shown in FIG. 3, but when the caller side ends the call, the connection process between the external line circuit and each circuit already performed in each step and each circuit The recovery process etc. is performed and the process ends.

  Next, the voice callable time timer process (S69, S80) in FIG. 3 will be described with reference to FIGS. When the processing of step S68 or step S79 is completed, the voice call response analysis processing means F52 refers to the voice callable time timer setting value set in the storage unit 19 in advance by the setting data storage means F52, and the voice callable time is set. The timer T1 is started (S91).

  After the timer T1 is started, the voice call response analysis processing means F52 analyzes whether the key telephone 20 has established a response to the voice call (S92). The establishment of the response of the key telephone 20 is determined based on whether or not step S74 is executed, and the transition control means F47 notifies the voice call response analysis processing means F52 of the completion of the execution of step S74 as an interrupt process, and the voice call response analysis processing means F52 When this interrupt is received, it is analyzed that the response is established. As a method of analyzing whether or not a response is established, the transition control means F47 stores the end of the processing in step S74 in the storage unit 19 by the temporary storage means F53, and the voice call response analysis processing means F52 stores the response to the storage unit 19. You may implement | achieve by confirming the completion | finish of a process of step 74. FIG.

  When the response is established (S92), the voice call response analysis processing means F52 ends the timer process (S93).

  If the response is not established (S92), the voice call response analysis processing means F52 determines whether the timer T1 has expired (S94), and if not, repeats the processing from step 92 to step 94.

  When the timer T1 expires (S94), the telephone extension information reception process (S71), telephone off-hook information reception process (S82) or telephone dial information reception process (S72) being executed in the main process shown in FIG. Is canceled (S95).

  The transfer control means F47 makes a call so that the paging circuit 17 connected to the external line circuit 13 in step S66 or the extension circuit 18 of the all-button telephone 20 connected to the external line circuit in step 77 is released from the communication path switch 12. The communication path control unit F44 is instructed to connect the voice guidance transmission unit 14 or tone transmission unit 15 and the output side communication path to the external line of the external line circuit 13 with the communication path switch 12 while instructing the path control unit F44. In addition, the voice call control means F48 calls the paging control means F45 or the data transmission / reception means F46 and the voice call to all the button telephones (or the button telephones in the group) 20 that have made the voice call via the extension circuit 18. An end notification is made (S96).

  When the connection of the voice guidance sending unit 14 to the communication path (S96) is completed, the transition control means F47 notifies the voice guidance control means F41 that there is no response (for example, “Called but not responded. The voice guidance from the voice guidance sending unit 14 is sent from the external line circuit 13 via the communication path switch 12. When the voice guidance is not used, the transition control unit F47 instructs the tone transmission control unit F42 to transmit a busy tone, and the busy tone from the tone transmission unit 15 (the transmission time is a fixed time depending on the setting). Is sent from the external line circuit 13 via the communication path switch 12 (S97).

  When transmission of voice guidance or busy sound (S97) is completed, an outside line disconnection process is performed (S98), and the timer process is terminated (S99).
