I got this number just now - 9/10 - It came up as "UNKNOWN NAME" on my caller ID. Didn't asnwer it (I hate answering unknown name calls) and there was no voice mail left.
I answered it, caller ID NY Cop too. He said he was a "paid solicitor" for a Firefighter organization. I hung up on him requesting I be put on their do not call list. Today is the 9/11 anniversary so I felt he was trying to take advantage of the day. After reading your posts it looks like I was wrong about trying to use today as an "opportunity" to do collections but I still think it's poor judgement at the very least.
I have gotten that same number about three times in the last two days but with no messages. We just got a new phone service and all the calls we get are non-profit people looking for money.
