I cannot find the Campus Directory on my phone.

Do you have the Cisco IP Phone 7940 or 7960? The Campus Directory is currently supported only on these phones. When you press the directory button do you see the fourth menu item and does it say 'Campus Directory'? Is your Directory URL set? To verify this press Settings, then scroll to Network Configuration and then proceed to Directories URL (entry 27 on the 7940 phone). It should be set to Neither of the two parameters can be set directly on the phone - they must be set by the CCS staff. If the Campus Directory is not configured on your phone then please contact the Help Centre at extension 58888.
