I reported this to the FCC complaint section which is separate from the Do Not Call Registry.  Coogle FCC Telephone Complaint.  They take this seriously and do follow up.  Register your complaint. There is power in numbers

I won't answer if the Caller ID reads "Unavailable," and I don't recognize the area code.  No message left.

This is Anne again - I just filed a complaint with the FTC.

Have received many calls from this number over time. Same comment as other. No one on other end. Probably a computer calling to nail down the most likely time you will be home. Common ploy. I have asked my number to be removed (Very quickly) and have just left the phone off the hook. Today I tried a dial back using my caller ID and got a jumbled bunch of static and not a return number dailing. These people are slimmy. Please help this number get disconnect. If you get calls from other solicitors, ask them where they got you number. Threaten to turn them over to the Federal Trade Commission. That might get their attention

I got a call from this number.  first there was a recorded message saying that President Obama wants us to re-negotiate our mortgage then had options to press.  I pressed one and a girl on the line asked me if I was interested--I told her I had no idea who she was and she hung up.  I'm worried that this is a scam and others might be pulled into it.

Got a call from them about 12:30PM today. Did not pick up and they left no voice mail. I went to the FCC site and filed a complaint: http://esupport.fcc.gov/complaints.htm
