I just keep answering and hanging up. From other research I've done, it may be Feature Films for Families who I used to buy from a lot, but they started using recordings when they called that ask you a bunch of questions and then answer in a computerized voice. I hate how impersonal it is, so even if it's them, I don't want to talk to them that way. They also call from a variety of numbers, some which are just a person's name, so I'm guessing they use telecommuters who call from their homes, but I want caller ID that spells out exactly who is calling and from where. I also want marketers that are willing to leave a message if I'm not available to talk, such as today while I'm battling laryngitis. If any sales people read this, please know that I am a buyer and don't block calls if the sales companies do the right thing. Too many have lost my business because I didn't like their practices. More their loss than mine.
