The Cisco Customer Directory Configuration Plugin is used to integrate Cisco CallManager with Enterprise Directory and can be used if you do not want to use the embedded Data Connection (DC) Directory. This plugin, which includes Netscape Directory Server and Microsoft Active Directory, installs only on servers that are running Cisco CallManager 3.0(10) or later. After the Lightweight Directory Access Protocol (LDAP) configuration completes, you can use the Corporate Directory service on your Cisco IP phone model 7940 or 7960 to look up users in the Enterprise Directory. You can also upload completed workflow application files to the directory.
For more information, consult the installation guide for the release of the Cisco CallManager you are using.
