You should really not pick these up. Many times it is a bot, or a telephone auto-dialer, that is just dialing random numbers to see if they are in service or not. When you pick up, the reason nobody says anything is because the bot now knows it's a working number, hangs up automatically, and the company behind the service can add your number to their list of working telephone numbers to sell to other companies. Basically, you are just making things worse by picking up because Do Not Call List or not, you are giving away your existence and more companies will call in the future. Never call back and Press any numbers to opt out for the same reason!
