Play/Record Extension
Before you finish adding an Auto Attendant to the system, specify the
extension number of the telephone at which you plan to record and play
your prompts and greetings. Typically, this is the extension of the person
who is configuring and administering the Auto Attendant. You can
record and play greetings for all future Auto Attendants from this
extension.
You cannot customize any greetings or prompts until you have specified
this extension.
You can specify a play/record extension in any of these locations:
NBX Messaging > Auto Attendant
■
NBX Messaging > Auto Attendant > Menu Tree > Prompt
■
NBX Messaging > Auto Attendant > Menu Tree > TD Greetings
■
NBX Messaging > Auto Attendant > System Wide Greetings
■
See the Help for the procedure on specifying a play/record extension.
