Calls every day multiple times and hangs up.

Past couple of days I have received calls from this number.
When I see it on the caller i.d. I do not answer it.
Can anyhthing be done about all of these annoying phone calls?
Some numbers register Unavailable with 3 U's (UUU) on the caller i.d.

I am on the national "Do Not Call List" but these a**holes found a way of getting around it.

Verizon, T-Mobil, AT&T and all of the other communication carriers, should be able to develop
a system that rejects these type of calls and unusual display of these numbers on the caller i.d.

I am receiving three calls a day with no voicemail.  I just don't pick up unknown numbers.  My husband did answer the phone with his well-known 'Daffy Duck' voice and the guy asked for me by name.  My husband backed off of the comedy thinking this was a real business call for me, but the guy hung up when he was asked "who's calling please?"

They were asking for a Peace Officers donation of some sort, but immediately hung up on me when I said we were going one direction with donation money this year.  Very rude.

Thank you, everyone, for the information.  Recently, I, too, have been getting at least daily calls, with "unavailable" listed after their phone number.  Why they would call me in Pennsylvania for their northern NJ "charity" is strange in addition to being exceedingly annoying.  Where do they get our numbers?
