### Answer To troubleshoot your call drop issues, consider the following steps: 1. **Call Ended Reasons**: Check the

endedReason

field in your call logs to determine why the calls are ending. Possible reasons can be found in the Vapi documentation under the [Call Ended Reason]() section [(1)]() . 2. **Server Events**: Ensure that your server is correctly receiving and processing the server events such as

end-of-call-report

. Details on server events and the end-of-call report can be found in the [Server Events]() documentation [(2)]() . 3. **End Call Triggers**: Verify if any phrases or conditions in your assistant's configuration might inadvertently trigger the call to end. The assistant configuration, including phrases that might trigger call termination, can be reviewed and updated using the [Update Assistant]() API [(3)]() . 4. **Webhooks**: Ensure that your webhooks are correctly set up and that Vapi is sending the appropriate POST requests to your server URL. For issues related to webhook triggers not firing, you might want to check both your server logs and the webhook configuration [(4)]() . By reviewing these aspects, you should be able to identify why calls are dropping and resolve the issue.
