probably called my home phone which is forwarded to Google Voice and redirected to my mobile.

Google Voice allows these types of calls to be blocked manually or automatically.

returned the call from another line and got a recording asking if I wanted a subscription but to their high call volume....disconnected.

This appears to be a telemarketer

Call

got a call from this #, answered but they hung up, sounds like may be a telemarketer checking out valid #'s.

NO RESPONSE

I just got a call too. I answered because I was expecting a furniture delivery. I answered, said hello twice and it disconnected.
Strange.
