We have implemented an outbound assistant that makes calls to phone numbers linked to specific project IDs. The assistant personalizes the calls using variables also associated with these project IDs. We now want to extend this functionality so that if a person calls back the same number, they are directed to the assistant, which would recognize the incoming phone number and provide information based on the corresponding project. Is this feature possible? We are struggling to find documentation on how to achieve this. Currently, the only solution we can think of is to create multiple assistants and assign each a different phone number linked to a specific project, but this approach isn't ideal. Could you provide guidance or documentation on how to handle this scenario more efficiently? Thank you for your assistance.

@mmaurel Absolutely, I can guide you through a more efficient approach to handle this scenario. You can indeed set up your system to recognize incoming calls and provide information based on the corresponding project without needing to assign different phone numbers to each assistant. Here's a high-level overview of how you can achieve this: 1. **Inbound Call Recognition**: When a call comes in, your system should capture the caller's phone number. 2. **Lookup Project ID**: Use the captured phone number to look up the associated project ID from your database or storage system where you map phone numbers to project IDs. 3. **Dynamic Assistant Configuration**: Once you have the project ID, you can dynamically configure the assistant to use the variables associated with that project ID. 4. **Assistant Invocation**: With the assistant configured, you can then direct the call to the assistant, which will handle the call using the personalized information for the project. To implement this, you would need to have a backend system that can handle the logic for steps 2 and 3. This system would be triggered upon an inbound call event. If you have an API endpoint for inbound calls, you can set up a webhook to notify your backend system of the event. If you need more specific guidance on how to set up the backend logic or if there are any particular features of VAPI that you are unsure about, please let me know, and I'll be happy to assist further. If there are any features of VAPI that you need more information on, please ask support for more info on this.

Thanks!
