FCC Warns About 'One Ring' Robocall Scam Seeking Callbacks To a Toll Number (nydailynews.com) 96

"Don't return that middle-of-the-night phone call if your cell phone only rang once," warns the New York Daily News: The Federal Communications Commission on Friday alerted consumers about a wave of "One Ring" robocalls after detecting "widespread overnight calling" in both New York and Arizona. The scam calls, also known as "Wangiri" -- which is Japanese for "one ring and drop" -- are an attempt to trick customers into phoning the number back. If you do, it can result in getting billed toll charges as though you called a 900 number... "They may call repeatedly, hoping the consumer calls back and runs up a toll that is largely paid to the scammer," the FCC said in a press release.

According to the FCC the callers are using the "222" country code of Mauritania, a nation in West Africa, to carry out their scheme. In addition to not returning the phone call, officials encouraged people against calling back numbers they don't recognize -- especially if they appear to be international.

            Keep a eye on your bill because they might try some weird shit. I got another call today from Sierra Leone. I don't understand why we put up with this shit. We know there are a lot of these calls coming from Sierra Leone. Why don't we, as a country, black list all calls coming from Sierra Leone until the government there fixes the scam problem?

        This is related to the FAS (False Answer Signal) problem of a decade ago. I had a phone company bill my company because there were 30 calls set up to a given number where 29 of them were active for more than 20 minutes. 30 calls is an entire E1 (like US T1 but with 6 more lines) worth calls.

            You can (and I have) ask your telco to put a "Third Party Billing Block" on your number.

            This covers "premium rate calls" (they won't go through) and any other company that tries to bill you through your phone number (like premium SMS services).

            Well worth the effort. You may need to spend some time finding out the exact term your carrier uses, but that's what AT&T called it when I had it added.

            Also, have them add a PIN code to your account. No changes can be made to the account without the PIN.

      So the solution isn't telling the government to crack down on the phone companies. It's refusing to use the phone companies and canceling service until one of the phone companies changes. Or start your own phone company. So there you go.

        • Well, a telco *could* block calls if the numbers mount up. If there are >n calls a minute from one source to different targets. I would guesstimate that the threshold of 5 would do. It would allow a real person to try several numbers, but would make large scale robocalling unfeasible.

          Another option would be to introduce an exponentially growing delay connecting calls for these people.

            Ok. A start at a definition. But how does Verizon, for example, know that a user in some foreign country using some other phone company has been making more than N calls per minute? And if N is a known value, then just make N-1 and you've bypassed this magical technological hurdle.

          Telcos can prevent that very easily by refusing to call foreign premium numbers. Or by blacklisting premium numbers once it gets known that they are used for fraud. Right now telcos act as the collection agents for known frauds, and that's where

            Telcos can prevent that very easily by refusing to call foreign premium numbers.

            Telcos aren't calling the numbers. People are. Some people will want to call such numbers. Did the telco sell you an incomplete service, that they won't let you call some of the numbers you want to call? Is this significantly different than network neutrality, in that the customer is paying for the service and the provider is putting up roadblocks?

          No. They are complicit when they are charging the customer and paying the scammers. Block the scammers. Unable to differentiate? Block all premium numbers.

As others have kindly explained, the carriers do profit from these calls because they collect charges from their customers, take their cut, then forward the rest to the scammers.

            I don't know that the local carrier gets a cut of the charge. Maybe they do. If so, it's done that way for all the premium numbers, not just the scammers. No US carrier signs a contract with a scammer saying they get a higher cut from scam calls.

            All the carriers would need is a little government regulation.

        I say they called a toll number, it was the number they intended to call, and they should pay the fee.

        The existence of asshats who call back unfamiliar numbers to harass anybody that might have called are the reason that nobody lets a stranger make a call from their phone. Even with unlimited minutes, it isn't worth the risk.

    • There is a lot of things Phone Companies can do to stop this influx of scam callers.
      1. Caller ID should be a trusted number. While there is good reasons to spoof your caller ID number, such as a call back goes to the main line at your company and not the callers direct line. But Companies and organization should have to register for these changes and probably pay a fee for every number being spoofed. Any complaint about a number should be able to be tracked back to the owner on who called you.

        There is a really easy fix. Realize that the USA has become copmpetely powerless, and don't answer your phone. At this point, if their number isn't in my address book - it doesn't get answered. And as soon as the Telcos allow thye spammers to access our phones and spoof people in our address books, everything will have to go to voicemail.

    • The telcos profit off of the connections. Just like the banks profit off of fraud. The difference is the banks are required by law to give you your money back when someone steals your credit card number (minus some nominal fee, though I don't know of any issuer that charges that fee), provided you report it on time. Most low level fraud goes undetected and unreported. Gas stations used to be the hot target, people would steal a number then buy gas cards with that number, then sell the gas cards for cash

The question is why they don't do it.
