anyone receive calls from this one?

Rang once.   Added to my block list.

This number has called my home on several occasions. It has never been answered but they also never leave a message. I tried calling the number back only to be greeted with the tape recorded tone and message that this number is no longer in service and that I should take a look at the number and try again. It's most likely spoofed.

Same: Caller calls your number and hangs up when you answer.  Sometimes there is an immediate second call.  Seems like a process to validate numbers so they can sell a "confirmed" list to telemarketers, or worse?
