Excel XP – Creating w/s for phone bills

Hello All 🙂
I have to create a worksheet for my company for the Phone Bills, that will show as to who (eg, Nancy, Steve, etc) has called which #’s and the amount of the calls made, Create an Excel worksheet where when my next bill comes I can paste the list in and press “Sort into who dialed the number” and each phone number and cost will be sorted so there’s a total for Accounting.
