I received calls from this number on my cell phone.  I called back the number early in the morning.  There is a message with an option to not be called again.  I suggest trying it.

I keep gettign calls from this number and when i answer, no one is there! and this is happening 2 times a day sometime!

It's a home security company trying to sell you a system, I've said no, I've said take me off your call list, I've reported them to the FCC...nothing works, not even changing my number...those [***]!

If you call the number back from your cell, a recording says you have the option to opt out of these calls by pressing 1. I tried it, worth a shot.

Just got another call from this number to my cell phone, last one was two days ago, also got a call with no one speaking when I answered on my land line a few minutes prior. One would think that with this much evidence, some government institution would be able to do something about this. I am guessing that tracing a repeated offender, or at least refusing to route calls from this originating number is not as difficult as balancing the federal budget. Wait - I just got ANOTHER call from the same number on my cell phone while typing this!
