I get calls from this number. There has been 10 of them in last 10 days. They hang up when it goes to answering machine. This is an invation of my privacy since it can even happen when I am in church.
The only way to block it is if your land line carrier offers call blocking, or if you have a smart phone (blackberry, etc) you can download a free app called Mr. Number Callblock. Once you put the number into that app, it will ring if they call, but only once, then the call gets disconnected and you get a notification that the call was blocked. It's a real pain in the [***].
