@kmichel, are you sure about this? We’ve had plenty of reps tell us why something failed in the past (based on Error number received, etc.,). I would think the company would be very strict on their reps if they did this and it wasn’t permitted. Are you certain about this being a violation? If so, we’ve had a lot of reps breaking the rules in the past!
They can tell exact errors that have occurred based on error numbers. @Millz laid out a good wiki that lays out how these errors are defined, here.
