It works via Chat function, but no via "Talk to Assistant" nor Phone calls... In the log, I can hear all of the voice communication from Caller and the Assistant, but there is no reaction from the Assistant after the First message... The call ends up on silence timeout...

SOLVED: Maybe it might help to someone. I just erased the API keys with 11 labs (I am using VAPI voice, but it is probably 11 labs voice...)

Hi KK18, If you're experiencing issues with your Vapi assistants not responding or calls dropping, a few things could be checked based on common causes: 1. **Check Call Logs**: Navigate to

Observe > Call Logs

in your [Vapi dashboard](https://dashboard.vapi.ai/) to review call transcripts and error messages that could indicate why an assistant is not responding. 2. **Verify Assistant Configurations**: Ensure that all required fields in the assistant or workflow settings are correctly configured, especially for any voice model or voicemail settings. You might want to verify configurations against the [assistant API reference](https://docs.vapi.ai/api-reference/assistants/list). 3. **Tool Integration Errors**: Check if any tool integrations are failing by navigating to

Observe > API Logs

. This can affect the assistant's ability to process and respond to calls. 4. **Provider or Network Issues**: Be sure to check the [Vapi Status Page](https://status.vapi.ai/) for any ongoing service issues. Similarly, verify the status of relevant language and voice service providers. 5. **Call Setup**: Confirm that your voicemail detection and voice model settings align with your use case. Details on configuring voicemail detection are available [here](https://docs.vapi.ai/calls/voicemail-detection). For any call dropping specifically: - Investigate if there is an

endedReason

code under the [call logs](https://dashboard.vapi.ai/calls) or refer to the call ended reason codes explained [here](https://docs.vapi.ai/calls/call-ended-reason). These steps could help diagnose and resolve your issue. If this doesn’t resolve the issue, please let us know and we’ll be happy to step in and assist further.
