Ask Slashdot: Dealing With VoIP Fraud/Phishing Scams?

An anonymous reader writes I run the IT department for a medium-sized online retailer, and we own a set of marketing toll-free numbers that route to our VoIP system for sales. Yesterday we began receiving dozens and now hundreds of calls from non-customers claiming that we're calling out from our system and offering them $1 million in prizes and asking for their checking account details (a classic phishing scheme). After verifying that our own system wasn't compromised, we realized that someone was spoofing the Caller ID of our company on a local phone number, and then they were forwarding call-backs to their number to one of our 1-800 numbers. We contacted the registered provider of the scammer's phone number, Level3, but they haven't been able to resolve the issue yet and have left the number active (apparently one of their sub-carriers owns it). At this point, the malicious party is auto-dialing half of the phone book in the DC metro area and it's causing harm to our business reputation. Disabling our inbound 800 number isn't really possible due to the legitimate marketing traffic. Do you have any suggestions?

There is no human solution.

Of course there's a human solution. My cousin Tony, from over there in East Jersey, he'll fix your problem right up with one visit. Your business, hey, it just needs a little protection.
