Hi Victor,
Were you using the Local Directory or using the url method to point to an external Directory? Here info related to both;
Cisco Unified Communications Manager Express Configuring Directories

Also have a look at this doc;

You only need to configure a url if you don't want to use the local directory. Have a look;
The Cisco CME system automatically creates a local phone directory according to the telephone numbers that are assigned during ephone-dn configuration. Additional entries to the local Cisco CME directory can be made using the directory entry command. The additional numbers can be nonlocal numbers, such as telephone numbers of other Cisco CME systems used by the same corporation.
By default, the router automatically uses the local directory service. Provisioning the directory URL to select an external directory resource disables the Cisco CME local directory service. You can also disable the local directory by entering the no service local-directory command.
telephony-service
Example:
Router(config)# telephony-service
Enters telephony-service configuration mode.
Step 2
service local-directory
Example:
Router(config-telephony)# service local-directory
enables local directory service on IP phones.
Step 3
exit
Example:
Router(config-telephony)# exit
Hope this helps!
Rob
