To check the directory via phone user interface:
1. Press the Dir soft key when the phone is idle.
The LCD screen displays the enabled list(s) in the directory.
If there is only one list in the directory, press the Dir soft key to enter this list directly.
Note
The built-in phone directory can store the names and phone numbers of your contacts.
You can store up to 1000 contacts and 48 groups in your phone's local directory. You can
add new groups and contacts, edit, delete or search for a contact, or simply dial a
contact number from the local directory.
To add a group to the local directory:
1. Press the Dir soft key.
The IP phone enters the local directory directly as there is only Local Directory
enabled in the directory by default.
Directory is configurable via web user interface only.
If the remote phone book and LDAP are not configured in advance, you cannot see
remote phone book and LDAP lists on the phone user interface. For more information on
remote phone book, refer to Remote Phone Book on page 59. For more information on
the LDAP, refer to
