Pre-record on landline on DNC for my "expired" car warranty. It was a voice response system, but I don't think it was a soundboard type. It got confused when it asked if my milage was less than 150,000 and I wouldn't use the word "yes". Maybe I should have in this case. If they call back, maybe I will so I can get to a person and find out more
I usually ignore numbers I don't recognize, but this one always stays on the line just long enough to trigger the voicemail (but never leaves a message) & it drives me nuts!!
