My parents are on the do not call list for their landline phone - but the calls keep coming on a daily basis! Always overseas call centres. (There's a slight delay before they can speak, which can give you hangup time if busy) - If not busy then it's fun to play with their minds & scripted spiel!
I've used the "wait a second while I attend the stove; crying baby, etc" & leave them hanging on timewaster many a time.
My all time greatest though is what my Dad does when he has time on his hands.... After thanking them for their call he says he needs the services of a telemarketer to promote his new concept for the American market - A life size blow up rubber dolly who F*r*ts to the tune of "The Star Spangled Banner" & can they help him with this? - The best response he ever got was a bloke from Mumbai saying "I've never been so insulted in all my life!" - Dad's response? Well you called me!
When Dad's playing with them like this they never get a word in - so he never knows what they were trying to sell him!
Sometimes he even asks about the weather; & having been to India & Pakistan as a young man; About places he's been, or their advice for an eldely traveller looking for a lady. My Dad has a warped sense of humour!
