You can provide access to the user to filter LDAP contacts search results. If you enable access, the search results from the LDAP directory only display contacts with phone numbers.

To enable or disable LDAP directory search, set the DIRENABLED_PLATFORM parameter and FILTER_LDAP_CONTACTS_WITHOUT_NUMBERS parameter to 1. By default, these parameters are set to 0 (Disabled).

Use the 46xxsettings.txt file or the phone web interface to configure access.
