I got this call at 10:13 am EDT, May 8, 2007, and the number was 712-945-0177. Since the number was unfamiliar to me, I let it ring and waited for a voicemail. No message was left. When I looked up the area code, I found this page with a list of many simlar numbers from that area code. I plan not to answer any of these calls.

hi. i got a call today from the same #.  they must have thought i picked up and asked for me on my voicemail.  they knew my name and said "hello" about 8 times. wierd.

Same thing - I called back and got put on hold in a queue.  This is a new number so I am curious to know if anyone else is using an IP based line as I am.  Also, they have called SEVERAL times  and they never leave a message.  Maybe some collections people?  I am going to block it.

UPDATE TO POST:
I am fairly ceratin that this is a collections agency.  I did some research and my results point to Premier Collections in Iowa.  (aka Premier Bankcard) with whom I do not have a card but do have a debt dispute with a creditor where they "bought" out the debt in dispute.

This is the 3rd time I have recived a call from this number. Every day its about 1pm central standard time. I answerd it only once. When I did there was no person on the onther end. Its getting anoying.
