### Answer Yes, it's viable to extract the phone number from the incoming call data and pass it to a function or tool call within Vapi. When you receive a call on Vapi, you can access the caller's number (often provided as 'from' or 'number') directly from the call object that is passed to your server URL defined for handling the phone number. Here’s a basic overview of how you might handle this using the server URL functionality in Vapi: 1. Set up a server URL in your phone number configuration that points to your server. 2. When a call is received, Vapi sends a POST request to your server URL with the call data, including the caller's number. 3. Extract the 'from' or 'number' from the call data in your server-side code. 4. You can then pass this number to any functions or tools as needed. This functionality relies on the configuration of the server URL and its handling in your backend systems. For more specific details or examples on how to set this up, you would typically refer to the [server URL documentation]() and the associated payload schema available there [(1)]() . Remember to ensure that your server is configured to handle requests securely and efficiently to process the incoming data as required.

Got it. Tagging @User for additional help.

It can be dynamic and not remeber the number becuase of the dynamic values you put in the prompt.

You just need to do the JSON part, not JS.

@Chowderr thanks but that doesn't work. 🙂
