Most people don’t have a land line anymore, nor are there many BBS’s online that are connected to the old phone system, so the only option is using VoIP to connect them. However if you read online, most people say it’s either not possible or would be painfully slow.
So, let’s see if we can get something working.

AP News: MagicJack's next act: disappearing cell phone fees

"The device is, in essence, a very small cellular tower for the home.
The size of a deck of cards, it plugs into a PC, which needs a broadband Internet connection. The device then detects when a compatible cell phone comes within 8 feet, and places a call to it. The user enters a short code on the phone. The phone is then linked to the magicJack, and as long as it's within range (YMax said it will cover a 3,000-square-foot home) magicJack routes the call itself, over the Internet, rather than going through the carrier's cellular tower. No minutes are subtracted from the user's account with the carrier. Any extra fees for international calls are subtracted from the user's account with magicJack, not the carrier."
