Description

  The present invention relates to a telephone device, and more particularly to a telephone device that detects, alerts, and reports a telephone call from a fraudster.

  Conventionally, various methods for repelling an unpleasant phone call that is not desired by a telephone user, such as a silent phone or a mischievous phone, have been proposed. There is a method of rejecting an incoming call from a non-notified telephone using the number notification. When the number is notified, the number can be stored and the second and subsequent incoming calls can be rejected. This is a method of storing a telephone number of a destination of consecutive malicious calls and determining whether an incoming call is accepted or rejected when an incoming call is received. In the case of a mischievous phone, there is a method of recording and returning it immediately. Below are some examples of prior art on how to block malicious calls.

  The "communication device with malicious incoming call rejection function" disclosed in Patent Document 1 prevents continuous malicious calls from the same source. As shown in FIG. 7A, the telephone number of the other party of the malicious telephone is stored in the malicious telephone number storage unit. The telephone number comparison unit compares the other party's telephone number at the time of incoming call with the telephone number registered in the malicious telephone number storage unit, and determines whether to accept the incoming call or reject the incoming call.

The “voice storage device” disclosed in Patent Document 2 automatically determines whether or not a voice message message is a malicious call, and automatically deletes the voice message message when the message is a malicious call. . As shown in FIG.7 (b), the message message by the voice from a sender | caller is recorded on a message message memory | storage part. Simultaneously with the recording of the voice message, the voice of the message message is converted into text data by the voice recognition unit. The converted text data is temporarily stored in the text storage unit. A word or a word assumed as a malicious call is registered in advance in the malicious call determination keyword storage unit. The words and words stored in the malicious call determination keyword storage unit are compared with the text data of the message message in the text storage unit. When the malicious call determination keyword (NG word) is included, the message message is deleted.
