Well, I was very dubious and had a strong suspicion what it would turn out to be, but played along anyway. "Okay, here it is. Now you call and if it cycles through a bunch of frequencies your line is okay, but if the number is busy, that means your line is tapped!" This person, in Miami, had regularly been calling this number in California to check his line. No, I didn't call it, and no, I didn't tell him he was an idiot. aem@mthvax.cs.miami.edu
