Combat unlawful robocalls with call authentication
We’re committed to fighting back against unwanted robocalls and increasing call answer rates with STIR/SHAKEN.
What is STIR/SHAKEN and why does it matter?
Increase call answer rates for trusted callers.
STIR/SHAKEN 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 STIR/SHAKEN ecosystem. If a caller abuses STIR/SHAKEN, they will be held accountable with near-instant traceback by regulatory groups and law enforcement.
Improve the reputation of your calls.
The STIR/SHAKEN 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.
