How STIR/SHAKEN Works and What it Means for Your Business

Voice carriers in the U.S. are required to implement STIR/SHAKEN. This framework helps detect and stop spoofed calls before they reach consumers, or display a warning notification on the caller ID.

Digital certificates are used to authenticate phone calls, similar to how Web transactions are validated. With STIR/SHAKEN in place, spoofed calls can be detected and stopped before they reach consumers, or a warning displayed on caller ID.

  • When a spoofer places a call, the originating carrier can’t verify that the entity is authorized to use that number, so no authentication token is attached.
  • Without a token, the call fails verification at the terminating carrier.
  • A warning is displayed on caller ID, or the call is blocked.

Anti-robocall measures like STIR/SHAKEN have hit enterprises especially hard with expanded call blocking and spam tagging mistakenly impacting legitimate business calls. As STIR/SHAKEN is rolled out across carriers, business callers could be flagged as having low-attestation levels on customer devices. These calls will automatically receive low grades even though there are real‒ likely trustworthy‒callers on the other end.
