Ported my "2005" number to a voip carrier, and have an automated lookup - not in my known caller list? Straight to voicemail. Known caller? Forward to my direct number with a known caller ID, otherwise muted. I should not have to put this much effort into not being contacted, but otoh, it saves me quite a bit since dropping the US cell line.
