Use old iPhone as a second phone over wifi but with primary phone number

Please help me design a method for using an old iPhone to make and receive calls on my current AT&T wireless number by WiFi, preferably for free. Ideally, I would like to have this old iPhone (without service), sitting on my desk, ringing when calls come into my current AT&T number, and when I make outgoing calls via Wifi, the caller ID shows my current number. The reason is primarily that AT&T coverage is horrible inside my house, so the ability to do this by wifi at home would be great. But I hate the confusion created when you make outgoing calls and the number is different. I can think of very convoluted ways to do it, so I'm asking you smarties if you have a better way.
