Hemet, CA on caller ID. No message left.

Same here.  I called back and a very cheery recorded female voice started giving me a sales pitch for some kind of energy service - translates as solar, I presume.  Offered several options including 9 to be put on their do not call list.  Might be a mistake but since it is apparently an actual functioning number, I thought I'd give it a try.  I mean, it's not like they all don't already have my number...

Answered but didn't say anything....She hung up. I called back and it said "Network Operations center, the party has decided not to accept calls from your number. Please add this number to your no not call list."

Called back it's a Solar Company. Advised to add my number to their do not call list.

Thanks guys! Idk voicemail empty. I called and pressed 9 do not call list, though I am on the National Do Not Call registry..maybe need to update. I don't feel bad now though..I did text back regarding my own business endeavors..thought perhaps it was in relation to one.....Oh well
