Shows a ton of info when someone calls your line and also allows you to make notes after every call that will be displayed on the NEXT call.
Ex. On the phone with client A, says they need X amount of product Z...Make note after call so that the next time they call you're not fumbling around talking about product Q because you know four "Wendy Wheelchairs".
Simple info like last time called, maybe family members' names, bday...What an amazing application that would be.
