I am attempting to modify the auto attendant (AA) on a Norstar Plus Modular ICS system. I am told internally that I have all of the corresponding manuals and assorted documentation for the system. There is a very basic AA on the system at the present time and on reviewing the setup I am unable to determine the meaning of the feature codes that are set up for the existing AA. Can anyone please let me know where to find the information in the manuals? I have examined the manuals and can not find any listing. If it is not in a manual, how would I go about obtaining the information?
