I am starting to think it does not matter wheather having landline phone for 911 or not. After reading and trying to locate specific sentence for phone companies requiring 911 calls to be made even with disconnected service. I don't think FCC wants to advertising them and cause phone companies to lose business, so they might have vaguely and said "At all the times" rather than "Even when service is disconnected" But both means same thing. Also, there has been alot changes going on especially wireless and internet 911 services. So, this sounded included internet relay service and making 911 available for Internet relay service is in the work. So, soon or later having landline phone just for 911 calls is just waste of money.
Also, alot deafies have wireless handheld devices. So the chance of one of them might use them to make 911 is even at greater! In some areas, you could just basically dial 911 (Even don't have to say anything verbally) on your sidekick and wait for cop to show up in matter of just minutes! When the 911 operator heard just pure silence, they will track where you are and send cop over there. Cool, eh? Perfect for would be victim of kidnapping, just dial 911 and the kidnapper will be in for surprise in just few minutes!
