What is SHAKEN/STIR and why does it matter?

Increase call answer rates for trusted callers.

SHAKEN/STIR is a protocol mandated by the FCC to combat the rise in unwanted robocalls and unlawful caller ID spoofing. When adopted, carriers can present a trust indicator, like “Caller Verified,” to recipients’ phones.

Stop telephone hijacking with near-instant traceback.

Fraudsters that illegally spoof caller IDs won’t be trusted in the SHAKEN/STIR ecosystem. If a caller abuses SHAKEN/STIR, they will be held accountable with near-instant traceback by regulatory groups and law enforcement.

Improve the reputation of your calls

The SHAKEN/STIR attestation given to calls is an important input to call analytic companies that service providers use to determine if a call should ring the handset as “Caller Verified” or “Potential Spam,” go straight to voicemail or get blocked.
