I may be misunderstanding you. I am saying you can use an structured data prompt to pull information from a call. You don't need a tool. You can have that information in the system, but you don't need it. You can have a simple propmt that just says "You are a helpful assistant" Then you have a structured data prompt that pulls "name", "email", and "number" If this is said doing the call it will be in the end of call report. No tool needed. Tools are really for when you are doing an action doing a call.
