Hi Vimal,
This should work in CCM 4.1(2). Likely you need to Stop/Start the TCD Service :)
Q. Why do line states of some directory numbers show unknown state?
A. Telephony Call Dispatcher (TCD) service is not started on all Cisco CallManager servers that have phones homed in. Start TCD services on all CallManager servers that have phones homed in. If this is an upgrade, make sure that you upgrade the TCD server on all Cisco CallManager servers in the cluster.
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.
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.
