Voice API Call resource now returns STIR/SHAKEN status
The Call resource now returns the STIR/SHAKEN status of each call. Check the attestation on your calls straight from the Calls API.
Carriers use STIR/SHAKEN attestation to decide how much to trust your caller ID. The stir_verstat property is returned when you fetch a call or read a list of calls, and it is fully integrated with the Twilio server-side SDKs.
Use it to confirm your calls carry A attestation and find calls signed at B or C so you can remediate.
