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.
