If you didn't snag a number when this was "GrandCentral" before it was
bought by google, I recommend signing up and reading up on this powerful
tool to be ready when google moves to restart the system.

While my aging phone needs don't make good use of the phone flexibility
that this _free_ service offers, I have helped several others set up
accounts which do really good things toward both making them available
to people calling multiple numbers, but, also, in allowing them to
control who can call them including when incoming calls will be routed
to specific numbers.
