When a call comes in an "Incoming Call” popup will appear. There is a grey “Hang up” button and a blue “Answer” button.
The grey hang up button dismisses the caller ID pop-up.
The blue "Answer button" opens a Customer window that auto-populates with the caller-id phone number. (If not signed in, it will prompt sign in before popping up the customer window).
How does it get setup?
The Caller ID setup is quite simple:
1) The client hooks the Caller ID box (aka "Whozz Calling? 2") up to their phone line and Revel network.
