The toll-free phone number
for technical support
. It's gone downhill

Anyway, this particular number has fallen into disuse partly because of the not-so-free support after 1 year, and partly because people would dial the O as a zero. Coincidentally, the number with a zero happens to be a sex chat hotline in the US. The same thing happened with one of the US Government's flood hotlines once.
Yes, I've accidentally done that
Phone: Hi, Baby! You've reached the sexiest chat line in America!
