I was surfing the web and came across what I thought was a very innovative product for public communications. It looks like it is the same size as a payphone but its FREE (atleast local and 800 calls). Instead of coin rev. they sell advertising to pay for the phone. Haven't seen one in my area yet but I called and they said they were demoing in certain markets first. I found it at. http://www.touchtonemedia.com. Let me know what you think.
