   We are currently observing elevated error rates affecting calls that use the Soniox transcriber. Impacted calls may terminate unexpectedly with the ended reason call.in-progress.error-vapifault-soniox-transcriber-failed. While we work to resolve this, we recommend switching to an alternative transcriber or configuring a transcriber fallback plan to ensure call continuity. You can set up fallbacks by following the guide here: https://docs.vapi.ai/customization/transcriber-fallback-plan We are actively monitoring the situation and will provide updates as more information becomes available.
