What to do if my Avaya 3730 IP Phone displays 'Phonebook is not available at the moment'?

If your Avaya IP Phone displays 'Phonebook is not available at the moment', it means the phone book is not responding. Try again later. If the issue persists, perform a factory reset via the Admin menu or PDM/Device Manager.
