The pay phone I bought from Bell South doesn't need coins, but it'll take them and drop them into where the coin box should be. If you pick up an extension phone while you're dropping in coins, you'll hear the appropriate red box tones. It's basically a giant, heavy, coin-operated red box. I could lug that thing around to pay phones and make free calls with it. Bell South sold me a toll fraud device. I bet I could technically be arrested for having it.
