Each Phonebook entry is based on one main extension or phone number, but it can have also have additional numbers associated with it. This way, you can have one Phonebook entry for a person, and have all of their contact numbers included in that entry.

Each entry's Additional Numbers are available from the View Additional Numbers icon for the entry.

Additional Numbers may have been created by an extension owner, or you can create them in your Phonebook entry.

• Additional Numbers entered by an extension owner are available when you add the extension to your Phonebook. These numbers appear as locked and cannot be edited, but you can choose to hide them in the Switchboard.

• Additional numbers that you add to your Phonebook entry can be edited and deleted.

• You can also copy any Additional Numbers (including the owner’s numbers), and then edit or delete the copy.
