SHAKEN/STIR – What do you need to do to ensure your calls get answered?

SHAKEN/STIR is a caller authentication framework aimed at reducing fraudulent robocalls and illegal phone number spoofing, helping restore trust in the telephone network. Developed by ATIS and the IETF, it uses a signing policy to authenticate calls, with different attestation levels indicating varying degrees of verification. To enable SHAKEN/STIR on outgoing calls, Twilio users need to onboard onto its TrustHub, creating business profiles and submitting for vetting, which can increase the chance of their calls getting answered.
