Why does when the user calls in, we get a value in {{customer.number}} sometimes and not all the times? Call ID: b519b898-0c97-4209-b339-f90cdfd397ac

The

{{customer.number}}

variable is only populated if the call payload or your server's response includes the customer's phone number. If this field is missing or not set correctly in your request or response, the variable will be empty. To ensure it is always available, make sure your server responds with the customer number like this:

json
{
  "customer": {
    "number": "+11234567890"
  }
}

Check your server logic to confirm the customer number is always included in every call event.

I am not making this call, I have twillio no and user is calling that no

I can help you figure out why {{customer.number}} doesn’t always show up. Most times this happens when the caller’s number is restricted, blocked, or hidden by their carrier. To dig deeper, I’d want to look at the VAPI logs for that call ID and compare with the calls where the number shows correctly. Do you notice if this only happens with certain callers, or is it random? @tnigam

I am calling from same number all the time, right now just testing

And If you would like assistance from VAPI, please continue this thread. Otherwise we will close it.

I have this issue too, except for me it never populates the customer.number

Please send a call id
