i”ve been trying to capture callers phone number when someone calls my agent, but Im unable to see any meta data and also the server url option for my phone number is also not available, what should I do?

I am facing the same problem

Hey, you can use the dynamic variable {{customer.number}} within the prompt to retrieve the customer number. Additionally, every and each payload from the VAPI site contains the customer number within the call object, so you can also extract it from there.
