OPTIONAL: The mailbox extension of the automated attendant to be used for this holiday. This can be a specific reference or a general one, for example, you can make separate extensions for such holidays as New Year's Day and Independence Day, or you can route to one extension for all holidays. If you choose separate extensions, be sure to record each greeting as described in
Step 3: Recording Greetings for the Automated Attendant Menu.
