DISABLED means no silence hangup, FIRST_MESSAGE_ONLY means only hangup if no first message is received, WHOLE_CALL means hangup after silence at any point in the call. - `silenceDurationSeconds` integer: The duration of silence in seconds before hanging up. - `ivrSilenceHangupConfiguration` SilenceHangupConfiguration, nullable - `type` 'DISABLED' | 'FIRST_MESSAGE_ONLY' | 'WHOLE_CALL', required: The type of silence hangup behavior.
