Thanks for sharing the details and error code. To help diagnose the Twilio Error 31920 (WebSocket handshake error), could you confirm if the server endpoint specified in your TwiML URL is currently configured to accept WebSocket connections and returns HTTP 101 during the handshake? This will help determine if the issue is with the server setup or the TwiML path. If you recently changed your server or deployment, please mention that as well.
