Didn't answer; called back with blocked ID.  Professional sounding answering system stating office hours & to call back when they aren't so busy.  Problem is they don't ID themselves!  Highly likely SOS for solar panels or reduce electric rates.

I got the same phone call on my cell phone..called back and male answered..I hung up..just called the number again got a detailed message of hours and if you wanted to placed on the do not call list....BUT.....they want name, address and landline phone number...SCAM
