What is False Answer Supervision?
False Answer Supervision is yet another type of VoIP fraud scenario. It basically refers to a situation where the answer signal is deliberately modified to charge for non-conversational time.
There are two flavors of false answer supervision. First, is when the fraudulent carrier returns the answer signal when ringing starts, rather than when the customer answers. This increases the duration of the call, and therefore the cost of the call. A call can even be charged if it is dropped due to no answer.
The more devious variant of this scheme involves call diversion. The fraudulent carrier will route the call to a recorded message that plays a ringing tone and then a recording that mimics an answer and conversation. This is intended to keep the calling customer on the line and paying for the call as long as possible.
