Yes, I guess swearing at them may do so, but most times, when I say I'm not interested, they just keep talking and try to keep me on the line. I've gotten quite used to just hanging up when they won't take my "I'm not interested" reply and they keep talking. At first, I felt kind of bad to do so, but that was really the only way. Thank goodness there's no listing for cell phones, but with other people (I'm sure there are some like me, who are getting fed up with telemarketers who switch to cells). Eventually when the shift comes, I'm sure it will be "open season" again. I dread that day and hope it comes much later than sooner.
