Why Robo-Calls Can't Be Stopped (washingtonpost.com)

"When your phone rings, there's about a 50 percent chance it's a spam robo-call," reports the Washington Post. Now a computer science professor who's researched robo-call technologies reveals the economics behind automatically dialing phone numbers "either randomly, or from massive databases compiled from automated Web searches, leaked databases of personal information and marketing data." It doesn't matter whether you've signed up with the federal Do Not Call Registry, although companies that call numbers on the list are supposed to be subject to large fines. The robo-callers ignore the list, and evade penalties because they can mask the true origins of their calls.... Each call costs a fraction of a cent -- and a successful robo-call scam can net millions of dollars. That more than pays for all the calls people ignored or hung up on, and provides cash for the next round. Casting an enormous net at low cost lets these scammers find a few gullible victims who can fund the whole operation...

Partly that's because their costs are low. Most phone calls are made and connected via the Internet, so robo-call companies can make tens of thousands, or even millions, of calls very cheaply. Many of the illegal robo-calls targeting the United States probably come from overseas -- which used to be extremely expensive but now is far cheaper...

Meanwhile, the Federal Communications Commission has been asking U.S. phone companies to filter calls and police their own systems to keep out robo-calls. It hasn't worked, mainly because it's too costly and technically difficult for phone companies to do that. It's hard to detect fake Caller ID information, and wrongly blocking a legitimate call could cause them legal problems.

The professor's article suggests guarding your phone number like you guard your credit card numbers. "Don't give your phone number to strangers, businesses or websites unless it's absolutely necessary."

"Of course, your phone number may already be widely known and available, either from telephone directories or websites, or just because you've had it for many years. In that case, you probably can't stop getting robo-calls."

      All that needs to happen is for ATT, Sprint, Verizon and T-Mobile to verify that an inbound call seeking to be completed on their network comes from the carrier that number belongs to. If it doesn't, then it should be rejected. If those four carriers alone started doing this, I'm pretty sure robocalls would collapse because so many of them wouldn't get through.

      One step better would be for all carriers to reject any inbound call using ANI that doesn't belong to that subscriber. Since individual carriers know what number blocks they are associated with and which blocks belong to their subscribers (all necessary for proper call termination), that database essentially exists, too.

      All this mumbo-jumbo of "what about VoIP" misses the point; the calls have to enter the public phone network someplace, and ultimately in the jungle of low-rent VoIP carriers are circuits that enable them to terminate calls on the major carriers, those circuits cost money and the carrier is keeping track of inbound calls.

      The international handshaking agreements between the telecoms companies of various nations means that the country receiving the call gets paid a small amount of the fees being charged by the originating telco.

      1. Block all international calls...
      2. ... except for this country where relatives live...

If it is not on your white-list, allow the caller to leave a message with the telco [which captures their number]. When you listen to the message, you get a push-button option to white-list or block the number, at that point.

      To cope with scenarios where someone is trying to reach you from an unrecognized number in a hurry, have the system offer, "Press 1 to return the call to this number" as an option.

      Telco's don't want to do anything because of the cost. But it's worth pointing out that if they fail to act, they are becoming actual accomplices in whatever fraud you might fall victim to. You might not be able to file suit against the originator, but there's no reason you can't go after their accomplices, is there?

      That's got to be worth a class-action attempt. To put this into perspective, remember the movie, "The Firm"... Each time the law firm mailed out invoices to their clients with over-stated claims for hours worked, that constituted mail fraud. With multiple companies receiving the invoices from multiple partners, that became racketeering, a RICO crime. As Tom Cruise mentions in the film, "That's more than you had on Capone".

      These robocallers are parasites, and they get away with what they're doing because they're not *enough* of a pest to get stomped on. But if we put pressure on the telcos to the point where it starts to *cost* them money rather than *make* them money, this crime will be stopped quick enough.

    Case in point: I've had the same phone number for nearly 20 years. I used it for both business and personal use over that time, exclusively (I've not had any other number that I've ever used). I don't have any fancy call blocking. I'm on the TPS. I get a stray call once in a blue moon (anecdotally, my work colleagues in the same office get several a week). I don't answer anything from anyone I don't know. They ring once, don't get an answer (because it rings silently) and then that's it... end of. It'll be another month or more before anyone I don't know tries to ring again.

    P.S. Political robocalls are basically illegal without explicit prior consent in the UK. Always have been. We also do not pay for receiving calls (even on mobiles) as some places do, so the cost is all on the sender and not on us. If the cost were on us too, we'd be up in arms.

    Since GDPR, there is also a huge axe to hold over their heads about where they got your number from, and whether they can prove explicit consent (they can't just say "well, we got your number from a list from one of our commercial partners" - which partner, when, what authority do you think that gave YOU to call me, did I explicitly say YOU could ring me or even handle that information, who gave that partner explciti consent to share

  21. The reason is that the cost is nothing. by Geoffrey.landis · · Score: 2

    They should turn it into a source or revenue for the phone companies. When a phone call completes, have an option for the recipient to charge them $1.00. The phone company keeps half.

    Even if it was a penny it would probably work...

    ^^^^

    This is it.

    The reason that there are a billion robocalls a day is that there is no cost to making a call. They don't pay for the resources they use.

    Even a penny a call would stop the robocalls dead. Even a tenth of a cent would stop them dead.
