Go to whitepages.com and select phone number option.  This number has appeared off and on for at least a couple of years.  Since the previous entry on here was 24 Jul 2014, it looks like it is back in play for the scammers.
Ignore.
Just keep reporting these A holes on as many sites as you can.  DNC list does not work with scammers.

Someone called from this number today and hung up. I called back, but went straight to voicemail; the voicemail greeting said the number I called is for "Alternative Energy" and to leave my name and number for them to call me back. I hung up the phone. My number is on the national do not call list.
