When the relocated telephone resets, it retains its Contact entries, like Concierge, but does not
allow the user to create new entries.
When you set APPSTAT to any valid value other than 1, the telephone does not accept any
Contact button label changes that might have been made directly on a backup file. Only the
existing labels of the telephone are used. This restriction prevents circumvention of the
APPSTAT restrictions.
