audiovox
My audiovox pager alarm comes with a picture of your car on it and lets you know exactly what part of your car is being touched, bumped, or looked at (depends on the sensitivity setting). The pager has 2 modes loud alert and vibrate alert. It covers the hood, windows, trunk, wheels(optional). It also has 3 alarm modes (reg, city, some other one I don't use). It also has the standard ignition kill and it is a very loud alarm. The range is up to 1500ft(and it actually does work from this far away) and the remote works through brick walls, cement, and metal. Best thing I did before moving to chicago.
P.S. This alarm is also pretty cheap. As far as cell phone calls, I don't know. Unless you had an autodialing phone already in the car. I don't know how the car would place the call or what it would say when you picked up, unless of course your david hasselhoff.
