    Im no expert, but the boyfriend said to buy a cordless phone that has one base station with multiple hand sets.

    Easy.
    With a plugpack and a simple crossover patch board.

    As long as there on the same phone line, you should just be able to pick up the receiver and talk to the other phone without dialing.

    hook them both to a 9volt battery. red / green. Ringing is a lot trickier. It takes a high volatge ac. MIKE
