Verify and store. In this case, the same outgoing call restriction storage phone is used regardless of which of the plurality of caller telephones (extension telephones) 4 within the same service beneficiary system is called. The same transmission restriction is applied based on the number data. For this reason, for example, the call origination telephone 4 is transmitted to the outgoing signal of the call origination telephone 4 so that the call origination control device 8 can recognize which service beneficiary system's call origination telephone (extension telephone) 4 originated. The specified outgoing telephone number is notified, and the outgoing telephone number is identified by the control unit 31 of the telephone outgoing restriction device 8. Then, the outgoing call restriction number storage means 42 stores the outgoing call restriction telephone number in the data storage unit 32 for each service beneficiary system, and the outgoing call restriction number collating means 36 has the calling telephone 4 that made the call. The outgoing call restriction telephone number stored for the service beneficiary system to which it belongs is collated, and the control unit 31 distinguishes the service beneficiary system and the voice communicated between the caller telephone 4 and the callee telephone 12. It is good to memorize | store a signal. In addition, the telephone call restriction device 8 may permit browsing and registration of the call restriction telephone number for the access from the terminal device 7 while distinguishing the service beneficiary system.

  The unit of the service beneficiary system may be for each company that provides the service, or for the same company, for each branch, or for each department.

  Further, in such a telephone call restriction system 1, it is also assumed that a telephone call can be made from the telephone 12 as an external telephone to the telephone 4 as an internal telephone. Therefore, a dial-in number is set for each service beneficiary system, and when a telephone call can be made from the telephone set 12 to the telephone set 4, a line is temporarily connected between the telephone set 12 and the telephone call restriction device 8, and dialing is performed. In response to the in-number, the telephone calling means 38 calls the telephone 4 of the service beneficiary system, and the telephone relay means 39 connects the line between the telephone 12 and the telephone transceiver 33, and the telephone 4 and the telephone transceiver 33. To the telephone transmitter / receiver 33. Further, the control unit 31 receives a digital audio signal communicated between the telephone set 12 and the telephone set 4 from the telephone transceiver 33 and stores it in the data storage unit 32. The user of the data service beneficiary system confirms the content of the call between the speaker of the telephone set 12 and the speaker of the telephone set 4 by downloading and playing back the voice signal stored in the data storage unit 32 to the terminal device 7. be able to.

  The present invention is not limited to the above embodiment.

  For example, the caller telephone 4 is a digital telephone in the above embodiment, but is not limited thereto, and may be an analog telephone or an IP telephone. Further, the call from the calling source telephone 4 to the telephone call restriction device 8 may not be a speed dial but may be a method of pressing a push button.
