I never answer the phone if I don’t know the number, because most are spam. But then I need to figure out if I should call back… I tried some call screening apps but they are both expensive and don’t work at all. Because I don’t have visual voicemail (thanks Vodafone), nor live voicemail or call screening (in the Netherlands, thanks Apple) I had to set up something myself. It took me a while to find something, but now I have something nicer then all those features.
