Twilio performs STIR/SHAKEN signing for direct customers

Twilio and Elastic SIP Trunking sign outgoing calls under the STIR/SHAKEN call authentication framework to increase call answer rates. Direct customers can create a Business Profile and enable STIR/SHAKEN in the Twilio Trust Hub and assign their Twilio local and toll-free US phone numbers to receive full attestation so that a trust indicator, “Caller Verified”, can be displayed on devices on participating destination networks.
