Yep, Caller ID is the way to go! When I see "Unavailable" I just don't answer. It is annoying to have to pay money each month to keep these people from pestering me but it is well worth it. I hope at some point in the future Telemarketers will be banned. Just my two cents. (My apologies to anyone out there who is a Telemarketer, but there must be a better way to make a living).
