If you ever wake up in the middle of the night and hear an intruder in your house, you need to think twice about using a cell phone to dial 911. Verizon's new cell phones have an alarm that sounds when someone calls 911. It's loud enough that it would be heard by the intruder. Or it might be heard by the guy who's beating his wife when his child tries to call for help.
Verizon says the alarm is required by a new FCC regulation. The FCC says that's not true, but they do have a requirement that new cell phones give some kind of signal so that a blind person will know that he accidentally dialed 911.
I'm thinking that when the operator says, "911 - what's your emergency?" that's a pretty good signal.
Bureaucrats are nuts.
