This service gives users a free phone number in just about any US area code. You can tell the service what to do when someone dials this number—from calling multiple phones at once, or going straight to voice mail.

We use it at our condo by having the box at the front door dial the GrandCentral number – which then calls my wife AND me at the same time. That way, whichever of us is at home waiting can get the call and answer the door.

I’ve wanted my grandmother to have this system – that way we could dial one number no matter which phone she is nearest.
