They call, answering machine picks up, plays my message, caller hangs up. Caller ID just says OUT OF AREA, even thought the area code is a local area code. I have call screening. I will never answer these calls. I just turn off all the ringers and if I happen to notice a call coming in, and I don't recognize the number, I just ignore these calls. If I do recognize the number, I pick up. People either reach me that way, by fluke, or they leave a message and I return the call. End of story.
11/10/16 16:00 PST Was on another call at the time this one came in. Didn't answer because ID was another of "V" numbers and although it went to VM, no actual message was left, just dead air. I'll block this one, as I do most of the anonymous ID calls.
