To correctly end an Execution for an inbound Voice call, Studio needs the “hangup” event from the Voice status callback. When that event is not received, the Execution may be left open (or “stuck”) indefinitely.

To address this, Studio now automatically configures the status callback shortly after configuring your phone number for Studio. This ensures the final “hangup” event is always received. With this release, manually setting the status callback is no longer necessary and helps avoid “stuck” Executions for inbound calls.

Twilio Elastic SIP Trunking now perform SHAKEN/STIR verification on incoming calls to your Twilio local phone numbers. It can be used to display a trust indicator or to make a routing decision, such as bypassing a voice captcha or IVR and directing the call to an end user.

A verified call that has been given the highest attestation under SHAKEN/STIR means that the carrier that originated the call both (1) knows the identity of the caller, and (2) knows the caller has the right to use the phone number as the caller ID.

There is a new header called X-Twilio-VerStat with the verification result. The new header is only present for incoming calls with SHAKEN PASSporT identity headers. Today, the United States is the only country where carriers instrument a call authentication framework like SHAKEN/STIR.
