Core Issue
The User Configuration window in Cisco CallManager Administration allows the administrator to add, search, display, and maintain information about Cisco CallManager users. Sometimes, if a user is not available in the Cisco CallManager Global Directory, then the user cannot be added in the Corporate Directory.
Resolution
In order to resolve this issue first add the user in the Cisco CallManager Global Directory, then add the user in the Corporate Directory. For more information on how to add users and troubleshoot, refer to Adding a New User and Fixing Issues with Corporate Directory Lookup from the Cisco IP Phone.
Problem Type
Call control software (CallManager, CallManager Express, ICS7750, SRST, SS7 call agents)
