With North American wiring I disconnected the house wiring from the incoming Telco wire, and then by plugging my VOIP blackbox into a wall jack was able to use any of the other jacks in the house with regular old fashioned phones. I think they have to be push button and not rotary.
Since then I've moved to a DECT / VOIP based home phone system which has worked great.
