I would suspect that most now have battery back up like mine does - even without power it screams! I understand about the phone but who is going to stick around with that noise?
When I was 16 or 17 we had a break in and there was atleast 3 people in our house late at night. My dad woke up to find one of them in their bedroom!!! They had all of the lights on and doors open. They were stealing the furniture also - they even were going to take the kitchen table (the chairs were already outside)!!! Talk about being violated!!
Always a alarm for me now - hell even a sign saying you have one is enough deterrent.

3. ADT is useless. If someone cuts your telephone line your alarm is useless. If you have a cellular backup, and someone gets to your main panel your alarm is useless. In any case the bad guys will get all they really want in less time than it takes for anyone to get there.
