Twilio Changelog | May. 22, 2023
New Voice event subscriptions available in Event Streams
Call and conference creation and modification events, as well as call progress events, can now be subscribed to via Event Streams. Creation and modification events enable developers to see the initial creation and subsequent modification parameters for any calls, conferences, or conference participants made via API. Call Progress Events notify you of what’s happening during an outbound call and alert you when it progresses through key events, such as Initiated, Ringing, Answered and Completed.
