Hi @darwin911, I'm an AI assistant for Vapi. I'll analyze available sources and get back to you shortly.

### Answer It sounds like you're experiencing a common issue related to call forwarding with Vapi. This problem often involves configurations with the

forwardingPhoneNumber

attribute or the invocation of the

transferCall

function. Here are a few points to consider: 1. **Forwarding Phone Number Attribute**: Ensure that the

forwardingPhoneNumber

attribute is correctly configured in your assistant settings. This attribute should be set to the number you wish to forward calls to [(1)]() . 2. **Transfer Call Function Usage**: The

transferCall

function should be used within your assistant's logic to trigger the call forwarding. Ensure that this function is being invoked correctly as per your assistant's logic [(2)]() . 3. **Error Handling and Troubleshooting**: If the call ends immediately after attempting to forward, it might indicate an issue with the call transfer process or the reception of the forwarded call. It's crucial to check the call logs for any errors or indications of why the call wasn't successfully forwarded [(3)]() . 4. **Twilio and SIP Support**: If your setup involves Twilio or specific SIP configurations, ensure that all necessary settings on those platforms are correctly configured to support call forwarding [(1)]() . If these steps do not resolve the issue, it may be related to more specific configurations in your setup or potential limitations with the current implementation of call forwarding with Vapi. Unfortunately, without direct access to detailed logs or the ability to investigate specific call IDs like

, providing a more precise solution is challenging. Consider reviewing the referenced documentation sections for further insi

ghts into configuring call forwarding and troubleshooting common issues.
