OK, that alone is a huge abuse target "Call this number for a recorded
traffic report (and advertisement)".

Even assuming that allowing reverse non-human audio is allowed and
common, what about the forward media?  Is it specifically required that
the caller be allowed to pass audio to the destination before ISUP ANS?
 Is is specifically prohibited?
