. This typically points to an internal processing or provider issue in the Vapi pipeline. To help narrow down the cause, could you let me know which voice provider (e.g., OpenAI, Azure, etc.) and model you are using for this call? This will help identify if the issue is related to a specific integration or configuration. If you have recently changed any settings or noticed a pattern (e.g., only certain calls fail), please mention that as well.

OpenAI 4.1 using playht as the voice.

To improve reliability and reduce call drops when your primary voice provider (PlayHT) fails, configure a voice fallback plan in your assistant's voice settings. Here’s an example of how to set this up in your assistant configuration:

json
"voice": {
  "provider": "playht",
  "voiceId": "your-playht-voice-id",
  "fallbackPlan": {
    "voices": [
      { "provider": "openai", "voiceId": "shimmer" },
      { "provider": "cartesia", "voiceId": "your-cartesia-voice-id" }
    ]
  }
}

This will automatically switch to the next provider if PlayHT encounters an error, helping prevent dropped calls.

I cant get my playHT key/userID to work in the API. Does it take a while? I have an active subscription

Hey CAKO, really sorry for your experience. If possible, could you record a loom video describing this error/behavior or inconsistency in the dashboard with the steps to reproduce it? That way, I can share this with my team, and we'll take a look. We'll even try to reproduce the same so we can fix it for you. Also, I'll request you to share your organization ID.
