Hi William,
Here is some starting off info;
Understanding the Cisco CallManager Attendant Console Directory
The attendant console server reads and caches directory entries at startup. After an initial handshake determines whether the directory entries changed since the previous log in, the attendant console downloads the directory user list. The attendant console also downloads the user list when the interval in the Directory Reload Interval field in the Attendant Settings dialog box expires or when the user clicks the Reload button in the Directory window.
The attendant console searches the following files (in order) for the user list:
User list file that is specified in the Path Name of Local Directory File in the Attendant Settings dialog box on the attendant PC
CorporateDirectory.txt file in the userlist directory on the Cisco CallManager Attendant Console server. You can create the CorporateDirectory.txt file if your user list is located on a directory server that is separate from the Cisco CallManager server.
--------------------------------------------------------------------------------
Note For information on creating a CorporateDirectory.txt file, see the "Creating the CorporateDirectory.txt File" section.
--------------------------------------------------------------------------------
AutoGenerated.txt file that is generated by the Cisco TCD service and stored in the userlist directory on the Cisco CallManager Attendant Console server. If the Directory Sync Period service parameter does not equal zero, Cisco TCD generates the AutoGenerated.txt file when the Cisco TCD service starts and when the directory sync period expires.
To modify the Directory Sync Period service parameter, choose Service > Service Parameters. Choose the appropriate server from the Server drop-down list box and choose the Cisco Telephony Call Dispatcher Service from the Service drop-down list box.
The user list file exists in comma separate value (CSV) format and contains the following information:
Last Name
First Name
Telephone Number
Department
--------------------------------------------------------------------------------
Note Directory entries without telephone numbers do not display in the attendant console Directory window.
