It sounds like you're facing a few challenges with implementing the transfer from AI to human feature on the Vapi platform. Let's break down the steps you can take to troubleshoot and resolve these issues: 1. **Check Your Tool Configuration**: - Ensure that the custom transfer tool you created is correctly linked to your AI assistant. This is crucial for triggering the transfer during interactions. 2. **Review the System Prompt Issue**: - If your system prompt was deleted after updating the workflow, it might be due to overwriting nested properties in your PATCH request. Make sure to preserve both updated and previous properties in your request to avoid this issue. You can do this by using:

javascript
     model: {...modelPrevProperties, ...updated}

3. **Verify Webhook Settings**: - Double-check that your webhook is correctly configured with the right URL and settings. This is essential for the transfer feature to work properly. 4. **Inspect Network Activity**: - Use your browser's developer tools to monitor network activity and check for any failed requests or errors during the setup. 5. **Test the Forwarding Number**: - Make sure the forwarding number you added is correctly formatted and accessible. You can test it by ensuring that your server can process incoming requests and provide a valid destination. 6. **Check Logs for Errors**: - Look at the Vapi logs and execution logs in your tools to identify any errors or issues in the automation flow. 7. **Fallback Measures**: - If the transfer fails, consider implementing fallback logic to route the call back to the AI agent to prevent disconnects. If you follow these steps and still encounter issues, it might be helpful to reach out to Vapi support for more specific guidance. They can assist you in retrieving the system prompt or resolving any issues related to the update process. Let me know if you need further assistance! 😊 Sources:

@alaskankid.907 for leaving voicemail message you require to configure it for your assistant, you can learn more about it from here https://docs.vapi.ai/phone-calling/voice-mail-detection

I called using phone a, calling the vapi assistant. I asked for an operator. It stated it was connecting me. And phone b, never rang. Never recieved a voicemail, never popped up on the call records either.

Then obviously since phone b never rang it brought the vapi assistant to prompt the no one was available thing.

I’m willing to do a zoom call or whatever you desire to show you.
