I now have to screen all my calls. Just received a call from this number, no voicemail. One search shows it is a voice over IP line and that's a red flag for me. Adding it to my blocked callers.
I don't answer unfamiliar calls either, but I do watch the logs. Usually others have already reported nuisance calls from the same number, confirming my suspicions that I didn't need to speak to whoever (whatever) called. I try to post when I get these calls from a number without any reports yet.
