Connecting Cordless Phones to a Cellular?

dmallery asks: "I live about 40 miles from the nearest Verizon cell. Last week, I put a 13db Yagi antenna about 18' up and voila: a reliable connection! The problem, of course, is that the phone has to be connected to the antenna to be usable. I have two wire lines that I'd love to get rid of, but you can barely hear the cell phone ring! Is there a way I can 'patch' from the digital phone to my cordless phones? There used to be something like that, but it was only for analog phones. Has anyone had this problem?"
