Your best defense is caller-id. I received a call from this number today and after three rings, they hung up. The donotcall registry will only help cut down on legitimate callers. These idiots have not compunction to get you removed from their lists and they use phantom phone numbers so it's impossible to trace the call back to where it originates. Do not answer any call coming from an area code you aren't familiar with. This will save you alot of frustration.
They call between certain hours to see if you will pick up, after a certain amount of calls, if you don't pick up as you don't know the #, they don't call anymore, it is also kind of a survey so they can send your # to other places to pin point when they can get you.
The "stop calling" does not work, they just use another # to call you from. So just don't answer #'s you don't know and believe me they don't call anymore.
Or either pick up the phone and answer Burger King like I used to that works to.
