Got a call from this number today. Left message on my answering machine about U.S. renewable energy program. To take this opportunity to reduce electric bill....blah..blah...blah. I have blocked every solar energy call to my home. Not interested to install.
Got some pre-recorded message about lowering my energy bill. Marked the number as spam in Google Voice and just to be safe added the number to the blocked contact list in Google Voice as well.
