Limiting Available Destinations
3JX3-07K
By limiting destinations that can be specified to those registered in the Address Book
or LDAP servers, you can reduce the possibility of specifying unintended destinations
and prevent users from leaking information. You can configure the setting to display
the confirmation screen to prevent the user from misdialing when specifying a coded
dial number in the Address Book.

Restricting New Destinations that Can Be Specified
Restrict destinations that can be specified when sending faxes or scanned documents to "those already registered in
the Address Book," "those previously used," or "those searchable from the LDAP servers." When this function is
enabled, the machine prohibits users from entering destinations using the numeric keys, adding new entries to the
Address Book, and editing the existing Address Book entries.
