received call from this number and phone said SPHE.  Talked to a woman who said she represented www.ghip.com which stood for Green Home Investment Program.  I looked them up on the web.  The information is vague and no details about who they are but seemed to represent a group of contractors (no names given) that provide solar, air and furnace, painting, vinyl windows, etc.  I tried to fine them on the Better Business Bureau and found nothing.  Also found nothing on the BBB by the phone number.  Sounds like a scam to me.
