to dynamically set the forwarding number for specific calls. This might help you work around the limitation. More details are available in the [dynamic call transfers documentation](https://docs.vapi.ai/documentation/advanced-concepts/calls/dynamic-call-transfers).
2. **Using Twilio as a Middle Layer**: You could forward calls from Twilio to the Vapi API. This approach is documented in this [advanced concepts guide](https://github.com/VapiAI/advanced-concepts-phone-call-provider-bypass).
3. **SIP Trunking**: Setting up SIP trunking might provide a way to route calls to multiple destinations. You can find more information about this at the [SIP documentation](https://vapi.notion.site/SIP-104008c8393f80feaeb7de8ca19565ed).
4. **Custom Tools**: Implementing custom tools might be another approach to handle call transfers beyond the current limitation.
5. **Server-based Routing**: If you keep the destination undefined, Vapi will call your server URL with a POST request, allowing you to handle routing logic on your server.
6. **Purchasing Additional Concurrent Lines**: The limitation might be related to concurrency limits. The default is 10 simultaneous calls, but you can purchase additional concurrent lines through the dashboard.
Is there a specific approach from these options that you'd like to explore further?
