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.
Holidays with no mailbox extension are ignored by the call routing function.
