Methods and systems are disclosed for blocking unwanted telephone calls utilizing a ring blocking device that works in conjunction with an external remote call blocking service. The call blocking service blocks unwanted calls by examining the caller ID information that is normally transmitted to a wireline telephone device during the silent interval between the first and second power ringing bursts of the call. The call blocking service compares the caller ID information to a blacklist of unwanted calling parties and ends the call if the incoming call's caller ID information matches an entry on the blacklist. The ring blocking device, which is typically located on the user premises, is configured to prevent the first power ringing burst from activating the telephone ringer, while also ensuring that the telephone reliably receives and displays the caller ID.

Disclosed is a communication disturbance analysis device, including: a hardware processor that: obtains a first recorded data created by recording a first communication sound at a transmitter in one facsimile communication and a second recorded data created by recording a second communication sound at a receiver in the one facsimile communication, detects a silence section from each of the first recorded data and the second recorded data; and specifies an extracted section to be extracted as a recoded data to be analyzed from the first recorded data and the second recorded data in accordance with the detected silence section.

Disclosed is a natural language processing (NLP) based call monitoring method for preventing voice phishing. The method includes the operations of: verifying a calling number ID when a call is received; when a voice signal of a caller is received, recognizing the caller's voiceprint, and firstly confirming whether the recognized voiceprint matches the voiceprint of a known voice phisher; based on the caller's speech keywords and speech patterns, secondly confirming whether voice phishing is or is not occurring; determining the caller as a voice phisher based on the risk score derived from the first confirmation and the second confirmation; and when the caller is determined as a voice phisher, taking corresponding measures. Therefore, frequency of damages due to voice phishing can be reduced.
