### Answer It sounds like you are facing a challenge with the

transferCall

function not executing as expected in your Vapi configuration. To troubleshoot this issue effectively, you'll want to review several aspects of your assistant's setup: 1. **Check the Assistant Configuration**: Ensure that your assistant's model configuration includes the

transferCall

function correctly and that the conditions for triggering this function are properly defined in the system's instructions. This function should be set up to activate when the support agent says "Transfer Call". Make sure that there is no typo or error in the trigger phrase and that the conditions are appropriately set to recognize the agent's intent [(1)]() . 2. **Review the Call Logs**: Check the call logs in the Vapi dashboard using your

call_id

to see if there are any errors or warnings that could indicate why the transfer is not occurring. The logs might give you insights into whether the assistant is recognizing the command to transfer the call or if there's an error in processing the request [(2)]() . 3. **Testing and Validation**: Test the scenario in a controlled environment to ensure that the assistant behaves as expected. You might want to simulate the conversation several times to pinpoint if the issue is with recognition of the intent or the execution of the transfer function itself. 4. **Assistant Model and Version**: Although you mentioned using GPT-4.0, verify that this version supports all the features and functions you are implementing, specifically the dynamic recognition of commands like "Transfer Call" in real-time conversations [(1)]() . If after these checks the issue still persists, you might consider reviewing the specific code

or configuration setup for your assistant to ensure everything is aligned correctly with Vapi's operational parameters as documented. If necessary, revisiting the documentation for function calling and assistant setup might provide additional insights or overlooked configuration needs. For detailed guidance on setting up and troubleshooting assistants, you can refer to the Vapi documentation on function calling and call handling, [(2)]() . This should provide comprehensive steps and checks to help resolve the issues you're encountering. ---
