We are testing a sales bot and noticed that in some calls, it just goes dead silent and does not say anything. I am attaching the callID: https://dashboard.vapi.ai/calls/f7e2e92c-e8e6-4fe0-8119-4e576816a040

Thanks for sharing the call ID. To help diagnose why the assistant went silent, could you please check the call log for this call and let me know what the "ended reason" or any error message says? This will help narrow down the cause. Source: - [Call End Reasons Documentation](https://docs.vapi.ai/calls/call-ended-reason)

It says "Silence Timed Out"

The "Silence Timed Out" reason means the call ended due to prolonged silence. To reduce these occurrences, try increasing the silence timeout in your assistant's configuration:

json
"silenceTimeoutSeconds": 60

This will allow up to 60 seconds of silence before the call ends. Adjust as needed for your use case. Reference: [Call End Reasons Documentation](https://docs.vapi.ai/calls/call-ended-reason) Source: - [Call End Reasons Documentation](https://docs.vapi.ai/calls/call-ended-reason)

But the assistant fell silent, not the customer. Instead, the assistant should have continued the call.

Thanks for clarifying that the assistant, not the customer, went silent. To help pinpoint the issue, could you please confirm if your assistant configuration includes a valid

firstMessage

and that both the Assistant ID and Text-to-Speech provider are correctly set? This will help rule out common setup issues that can cause the assistant to not speak during calls.

I'm seeing similar issues, but only when I have a Rime.Ai voice in use. Swapping to a different voice provider seems to solve the problem. Are you using Rime vocies by chance?

No, I haven't used Rime

Looking into it

Same issue. I made an issue with more info and call ids etc.

Switching voice providers is the best option here.
