This phone system [
link] lets you use cell phones with a multi-handset cordless home phone system. As described by someone I work with:
"
At our house we
dropped the home phone because already had 2 different cells in the house.
But, for convenience,
got a combo cordless phone/answering machine with cell phone integration.
For example, Panasonic makes a base station with 3, 4, or 5 cordless handsets –
that gets a cordless phone in each major room…. Plus an answering
machine. The Panasonic also integrates up to 3 cell phones with
Bluetooth.
So you come home, put
your cell phone near the base station for charging. It ties in via
bluetooth. If a phone call comes in, all the cordless phones ring.
And it is a distinctive ring to differentiate one cell from another. So
dad’s ringtone in the house is different than the ringtone for mom.
Placing a phone call is easy too, when you pick up a cordless, it will go out
on cell #1. If you hit Flash 2, then it goes out on cell #2 and so on."
