AT&T Is Adding a Spam Filter For Phone Calls (theverge.com)

An anonymous reader quotes a report from The Verge: Today, ATT introduced a new service for automated blocking of fraud or spam calls. Dubbed ATT Call Protect, the system identifies specific numbers believed to be sources of fraud, and will either deliver those calls with a warning or block them outright. Users can whitelist specific numbers, although temporary blocks require downloading a separate Call Protect app. The feature is only available on postpaid iOS and Android devices, and can be activated through the MyATT system. Phone companies have allowed for manual number blocking for years, and third-party apps like Whitepages and Privacystar use larger databases of untrustworthy numbers to preemptively block calls from the outside. But ATT's new system would build in those warnings at the network level, and give operators more comprehensive data when assembling suspected numbers. More broadly, marketing calls are subject to the national Do Not Call registry. Specific instances of fraud can still be reported through carriers or directly to police.

      No, not really.

      What the scammers do is spoof Caller ID information. That is also the ONLY blocking method phone carriers have provided. There's no way for subscribers to block the actual AN.
      A lot of carriers have cracked down on Caller ID spoofing, so the scammers will rely on shady offshore phone companies which still allow it, and/or VOIP services which also still allow the subscriber to set their own Caller ID data. Any telco with a shred of legitimacy will have that ability disabled, and only allow 'spoofing' when it's something like a customer with multiple lines who wants them all to present the same Caller ID... and then they'll set the ID data up FOR the customer, not simply relay what the subscriber tells them to.

      If AT&T can tell that it is a spoofed caller ID, then they could automatically block the call.

      There are a lot of legitimate reasons why caller ID might not match the AN setting up the call. Unless the caller is actually an AT&T customer, there is not much they can do to determine if it's a legit spoof or not.
      One example of legit spoofing is when you have two or more phone numbers, and only want to get Inbound calls on one specific number, or possibly have inbound calls go to an 800 number you own. You can have your telco spoof the caller ID on all your lines to deliver the same number. You'll see a lot of companies do this with the cell phones they give to their Field Technicians... they deliver a Caller ID which goes back to the central support center or Dispatcher.

      But the way it's supposed to work is that the telco sets that up FOR the customer, after verifying the spoofed number is valid and legitimately owned by that same person or company. But a lot of lazy, inept, or just plain corrupt companies exist which allow customers to send the Caller ID themselves. Other companies can't normally tell what is legit and what is not. And more to the point, performing the verification is a manual process, there's really isn't any way to automate it, especially not at the time a call is being made.
