Spam and robocalls are such a widespread problem -- Americans endured over 26 billion of them in 2018 -- that the FCC has stepped in, fining four companies responsible for billions of robocalls. Stopping robocalls on your own is one thing, but the FCC has also tasked the communications industry with curbing the number of robocalls we all receive on a daily basis. Recently, 12 phone companies and 51 state attorneys general announced a plan to implement technology to identify, and eventually block, robocalls. This is where STIR/SHAKEN (also called SHAKEN/STIR) comes in.

Tips to stop robocalls

What is spoofing?

More often than not, spam and robocalls originate from spoofed phone numbers. A spoofed number means the caller has intentionally faked caller ID information, displaying a number they don't own. Scammers can use phone numbers you know, such as those of loved ones, a company, a government agency or a local phone number to give you the impression that a call is legit.

How STIR / SHAKEN works in a network. A SIP INVITE is received by the originating telephone service provider. The originating telephone service provider checks the call source and calling number to determine how to attest for the validity of the calling number.

Call spoofing is important to spammers and scammers because you're more likely to answer a call from a number you think is valid, and answering a spam call proves that your number leads to a real person. The more you pick up, the more robocalls you're likely to receive.

What do the SHAKEN/STIR acronyms stand for?

How does SHAKEN/STIR work?

The short version of how SHAKEN/STIR works across independent service providers is this:

When you place a call using Service Provider A's service, that company verifies the call and attaches a digital signature that indicates it originated from a valid caller ID. Service Provider B receives the call, checks the signature, validates it again, and then shows the recipient that the call is verified -- it truly originated from the number shown on caller ID.

How do I know if a call is verified?

You'll see a message on your phone's screen when a caller has been verified. T-Mobile users will see "Caller Verified" just below the phone number, as seen in the screenshot to the right.

Will I quit receiving robocalls?

Unfortunately, not yet. SHAKEN/STIR doesn't block or stop unverified calls from getting to your phone, but it can be used to help identify those who are placing spam calls and shut them down. You will, however, have a better idea of which calls to answer when you see caller ID text that says "Caller Verified."

Additionally, phone companies can use the verification technology to build more robust robocall blocking apps and services, but we're not quite there yet.

Wilfried Zaha criticises "sad and annoying" speculation

Wilfried Zaha criticises Palace star Wilfried Zaha has hit out at speculation and rumours linking him with a move away from Selhurst Park this Summer. Speaking on Twitter, Zaha revealed he felt “sad and annoyed” at people speaking on “things they know nothing about” amid speculation that the Palace attacker will move to Arsenal this Summer. Twitter: Whatever happened to speaking facts ?its sad and annoying how anyone will just open their mouth and speak on things… https://t.co/ZmnxXAEi9L (@wilfriedzaha) Zaha’s brother had previously stated that it was Wilfried’s dream to play for Arsenal, and to eventually play in the UEFA Champions League.

The message appears to have hit tech stocks hard, with shares in Apple and several US chipmakers dropping. • New SHAKEN / STIR technology will put an end to annoying robocalls .

Yet the number of robocalls continues to hit new highs. The anti-robocalling company YouMail ATIS and the newly formed governing bodies of STIR and SHAKEN are still figuring out what exactly And while STIR and SHAKEN will make it harder for robocallers to rely on spoofed numbers, they'll still be

Do I need an app or special software to use the protocol?

Right now, call verification only works on select phones. Currently, T-Mobile and Metro customers with the following devices will see the verified message if they're running the latest device software:

  • Samsung Galaxy Note 8
  • Samsung Galaxy Note 9
  • Samsung Galaxy S8
  • Samsung Galaxy S8 Plus
  • Samsung Galaxy S9
  • Samsung Galaxy S9 Plus
  • Samsung Galaxy S10e
  • Samsung Galaxy S10
  • Samsung Galaxy S10 Plus
  • LG G7 ThinQ
  • LG G8 ThinQ
  • LG V40 ThinQ

Notice, Apple's iPhone isn't currently on that list.

AT&T hasn't yet announced which devices will display a similar verified message.

When will Verizon and Sprint get on board?

If the FCC has its way, by the end of 2019. Verizon is already using the SHAKEN/STIR protocol for calls within its own network, but hasn't expanded to support outside providers. Sprint hasn't made any formal announcements, but according to a letter sent to the FCC in late 2018, the carrier expects to begin testing in the second half of 2019.

As more carriers announce SHAKEN/STIR interoperability, we'll update this post with the latest information, including devices when available.

With the FCC's requested implementation deadline nearing, hopefully, we'll begin to see more agreements announced and phones added to the compatibility list, making it easier to know when we should answer a random call, or let it go to voicemail.

In the meantime, make sure you're doing everything you can to limit the number of robocalls you receive. Even if that means doing a little spoofing of your own.
