SHAKEN/STIR for Programmable Voice in the United States

Twilio Programmable Voice signs outgoing calls under the SHAKEN/STIR call authentication framework to increase call answer rates. Customers can create a Business Profile and enable SHAKEN/STIR in the Twilio Trust Hub or with the Twilio Trust API and assign their Twilio local and toll-free US phone numbers to receive full attestation on their outbound calls. This can lead to a trust indicator, “Caller Verified”, being displayed on devices on participating destination networks.
