Wangiri Warnings in Canada

Several Canadian telecommunications service providers have warned their customers to avoid answering or returning calls from unknown international numbers. This type of telecom fraud is called “Wangiri,” which is Japanese for “one and cut.” Here's how it works.

A fraudster sets up a computer to dial phone numbers so that each call rings just once, then hangs up. This leaves a missed call on the recipients’ phones. Some users will call back, and the callback is to a high-cost premium rate number. It’s an old trick, but even a small callback rate is a moneymaker for fraudsters.

TransNexus SIP Analytics® software, available in the cloud in ClearIP or on-premises in NexOSS, can automatically and rapidly detect and block Wangiri fraud attacks.
