Silent rest
conference_participant removed from Voice Insights Call Summary on August 1, 2026; all calls now return attributes: null
What changes
Announced July 1, 2026. Removed from the REST API and Event Streams on August 1, 2026. Before, it was populated only for calls eligible to join a Twilio conference and all others returned attributes: null; after removal every call returns attributes: null. Logic that assumes the data is present silently degrades.
Silent: No error. Behavior, results, or cost change quietly.
What to do
Source conference data from the Conference Insights API or Conference Insights Event Streams; add a test for the null case.
