Is there a way to get the customer’s phone number in the assistant’s built-in analysis prompt? I tried using

{{phoneNumber}}

but it didn't work.

You can't use

{{phoneNumber}}

directly in the assistant's built-in analysis prompt. However, you can access the customer's phone number in your server webhook like this:

js
const incomingNumber = req.body?.call?.from?.phoneNumber;

Use this value in your server logic to filter or route calls as needed. Reference: [Vapi documentation – Spam call rejection](https://docs.vapi.ai/server-url/spam-call-rejection) Source: - [Vapi documentation – Spam call rejection](https://docs.vapi.ai/server-url/spam-call-rejection)

you can use {{customer.number}}
