The issue has been resolved. After applying the remediation, we monitored the affected systems and confirmed stable operation. All services are functioning normally.

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
