STIR/SHAKEN call authentication will identify the entity behind the call.

STIR (Secure Telephone Identity Revisited) / SHAKEN (Signature-based Handling of Asserted information using toKENs) is a framework designed to assign a certificate of authenticity to each phone call for use across the telecom network. These certificates will act as a digital signature of trust passed from carrier to carrier to improve traceable call delivery.

The FCC is leading the push for industry adoption of these standards to improve the ability to trace back to illegal call origination across all carriers. As of March 31, 2020, the FCC has mandated that both originating and terminating voice service providers implement the STIR/SHAKEN caller ID authentication framework in the IP portions of their networks by June 30, 2021. STIR/SHAKEN is also mandated by the TRACED Act.

Once implemented, STIR/SHAKEN should provide the identity of origination of calls into the network, operationally across all carriers. Secondary benefits could include the identification of verified calling identities through what is known as attestation.

How to achieve STIR/SHAKEN verified calls

Numeracle has joined together with NetNumber, STI Certification Authority (STI-CA) and leading provider of a comprehensive portfolio of STIR/SHAKEN solutions, to deliver Verified Caller Identity for STIR/SHAKEN, a joint solution to improve the delivery of legal enterprise calls through STIR/SHAKEN caller ID authentication and RCD (rich call data) display.

The joint Verified Caller Identity for STIR/SHAKEN solution will be delivered through an extension of Numeracle’s Verified Identity™ and Entity Identity Management™ platforms to include NetNumber’s Guaranteed Caller™ Enterprise STIR/SHAKEN solution set. This solution enables legitimate enterprise calls to be displayed on the called party’s device as verified through STIR/SHAKEN. Follow us through the end-to-end call authentication journey calls will take below:

STIR/SHAKEN and Verified Identity™

You & Your Carrier

Who Calls the Shots?

Enterprise Identity
More often than not, there are many 'layers' between an enterprise caller and the originating service provider responsible for generating call traffic on your behalf (i.e. dialing and CX platforms, multiple BPOs, outsourced call center partners, telephony vendors, etc.).
Call authentication through STIR/SHAKEN is all about validating the identity of a caller by connecting the dots between an enterprise, its call center vendors, and its originating carriers. You can start this process now by becoming a Numeracle Verified Identity™.
With so many 'layers,' it can be hard to prove who actually has authorization to originate traffic on your behalf when it matters most. We believe you (the enterprise) is in the best position to know who has the authorization to use any specific telephone numbers when making calls.

Will STIR/SHAKEN stop all robocalls?
While STIR/SHAKEN will help identify harmful robocalls, it will not completely eliminate all illegal robocalls for good. It's also important to note that not all robocalls are bad. Many legitimate companies communicate all sorts of information via 'robocall,' such as appointment reminders, delivery notifications, school closures, etc.

So while STIR/SHAKEN is not a silver bullet solution, and it cannot determine the illegitimacy or legitimacy of the intent of an incoming call, it can validate that an incoming call is originating from a real phone number, a number which is not being 'made up' or stolen from a legitimate business, organization, or consumer.

The STIR/SHAKEN framework does not have the ability to weigh in on whether or not the content of the call itself is potentially malicious or unwanted (this is where call blocking and labeling analytics come in). Thus, this technology is not able to stop all robocalls, but it will be helpful in identifying those generated using illegal spoofing tactics.
How does STIR/SHAKEN stop illegally spoofed calls?
The absence of this technology in the past is what has allowed bad actors to represent themselves as someone they’re not by illegally "spoofing" or hiding behind a falsely presented telephone number. With the improved ability to trace back to the origination of illegal activity, STIR/SHAKEN will assist government and telecom entities' ability to identify and stop the source of the illegal robocalls.
What is "call authentication?"
"Call authentication" is all about validating the identity of a caller by connecting the dots between the enterprise or contact center and its originating carrier(s) (telco providers) to ensure its calls are identified as trusted from the point of origination to termination. Once the originating service provider has validated your identity as associated with your outpulsed phone number (see: NumeraCert Verified Identity to learn more about this process), the next step is for the terminating device (the phone of the person you’re calling) to authenticate the identity + phone number information passed from the originating service provider in order to display the call as a Verified Call (or not, if the identity + phone number can not be validated).
How will "Verified" calls be displayed?
Some of the specificities around exactly how the "Verified" calls will be visually depicted are still a work in progress, but the requirements to trace back to the identity of the caller are mandated by the TRACED Act, and service providers are actively working to ensure they meet these requirements to avoid interruptions to service or calls blocked as the result. Taking the steps now to ensure your identity (branded calling presence) as associated with the authorized use of your phone numbers has been verified (see: Verified Identity Certification process) provides the "Know Your Customer" evidence required to validate your identity to the service providers passing the STIR/SHAKEN signed call to the point of termination (on the phone of the person you're calling), which will prevent the improper blocking of your calls, and enable the highest levels of attestation (or authentication and visual depiction of the Verified status) possible.
Whose responsibility is STIR/SHAKEN?
The logistics behind implementing STIR/SHAKEN do not fall to you, but to your telco provider. That said, we recommend you keep pace with your service provider’s progression toward STIR/SHAKEN implementation so you can ensure your calls will be given the greatest opportunity to be successfully 'authenticated.'

With much still in the works behind the scenes with STIR/SHAKEN, it's also very important for you to voice your opinion and weigh in on policies that will impact your business. Also, be wary of solutions with ‘guarantees’ on STIR/SHAKEN, especially those with promises for 'enterprise signing' or 'attestation.' Nothing has been finalized, so at this point, it's impossible to predict exact outcomes with 100% certainty.
