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?
