FAS fraud
FAS (False Answer Supervision) is a very common type of fraud in VoIP wholesale business. I'll try to briefly explain what it is, how it works and how to detect it.
Let's consider a following scenario. Our company has an interconnection with EvilVoip company. We made an agreement that they will terminate traffic to Nigeria mobile at $0.07 per minute. We sell that traffic to our customer at say $0.09 per minute. So far so good. A call comes from our customer, we route it to EvilVoip, the phone conversation's duration is 60 seconds, we made $0.02 on that call. Everything is fine. Now, EvilVoip gets nasty and greedy, wanting to raise their profit. So they make a little change in their routing so that the calls from our customer (that we send over to EvilVoip) don't get terminated on the target number but instead they end up locally at EvilVoip's custom IVR that does nothing more than playback a prerecorded message saying something like "Hello? Hello? I can't hear you well! Can you repeat? Please, who is calling?". The caller (from our customer) is actually convinced that the connection is of poor quality and tries to talk to the recorded voice for, say, 30 seconds before he hangs up.
What happened here. We charge our customer 30 seconds, but he never got connected to the dialed number. We also pay 30 seconds worth to EvilVoip. EvilVoip, however, does not pay anyone because the call wasn't terminated to the target network, but ended up locally at their IVR. EvilVoip just earned $0.035 (half minute of $0.07) but the call never connected the caller and the callee.
To get more nasty, EvilVoip can configure their equipment so that every 10th call gets to the IVR, making it very difficult for us to detect the fraud because we'll have to make 10 or 20 calls to catch one fraudulent call. Now what can we do about it?
Our automated VoIP route quality testing system, RouteInspector, used by many VoIP wholesale providers is an essential tool for detecting such kind of fraudulent routes. RouteInspector makes voice calls through your softswitch, records signalling and media flow, analyzes it and inspects it for FAS fraud. By analyzing the signalling and media flow of voice calls, RouteInspector's versatile FAS (False Answer Supervision) detection system is able to detect nearly all FAS scenarios. Timely detection of fraudulent routes protects your business by giving you the opportunity to reroute your traffic before your customers do!
A typical route test report looks like this:
For every call you get a detailed report with relevant metrics to determine the call's quality, gives you the opportunity to listen the recording of each call and performs FAS fraud detection on each call, indicating potentially problematic calls.
It is an extremely useful tool to monitor your routes' quality which is essential to any VoIP provider.
