Cisco 6821 Administration Guide

Reverse name lookup is enabled by default.
Reverse name lookup searches the directories in the following order:
1. Phone contacts
2. Call History
3. LDAP Directory
4. XML Directory
The phone searches the XML directory using this format: directory_url?n=incoming_call_number.
Example: For a multiplatform phone using a third-party service, the phone number (1234) search query has
this format, http://your-service.com/dir.xml?n=1234.
