I have an assistant up and running that takes inbound calls, I have a end of call report set up in order to capture a call even if it did not complete. One of the items defined in the structured data is the {{customer.number}} , however if the call is terminated very early, say during the first message, the {{customer.number}} is empty. Can you advise on what I need to do, in order to ensure that {{customer.number}} is captured even if the call is terminated upon connection
