I had another permutation of this last week...There was a message on my answerphone saying something along the lines of:

" You have an important message from kn0b-head marketing. To listen to the message press 1; to save the message press 2 ; to delete the message press 3"

Not sure how it works, but I'd be willing to bet that, if you picked up the phone, listened to this message, then pressed 1,2 or 3, you would be calling them on a premium line.
