I don't recall, but the HFAI condition may be one of the states that are not saved in the AMS backup file. If so--AND knowing that sometimes customers are, uh "mistaken" about the way things were before the problem arose--then it makes sense that a system reboot would give these results.

What do you mean by "this is affecting DND"?

It's possible that the AUDIX integration file is trashed, thus causing irregular MWI On/Off mode codes to be sent to the extensions. Certain dial strings can turn off or on things like DND (and possibly the HFAI feature).
