FAS is perhaps the most prevalent and is under the control of international carriers. So what is FAS? FAS occurs when a call is falsely answered by a downstream carrier so they can start billing well in advance of the real answer. Even worse for customers is a phenomenon, known as call hijacking, where the call is routed to an automated voice system designed to keep them on the phone while billing continues; not only do they get a huge bill, but the call does not even reach the dialed customer.
