Anyone with a pair of eyes can physically see the land line piped into said elevator controller.

You harp on people not embracing new wireless technology, what you seem to overlook is the point of the emergency phone itself. Land lines are currently the most reliable way to transmit. I wouldn't want to get trapped and put my life on the line because a landlord or building owner wanted to save a couple bucks.

I see that others have tried to give the same advice and you just keep defending this like you have stock in the wireless companies or something. Perhaps should you should go troll elsewhere.
