Why does my Cisco IP Phone display XML Error [4] during a Corporate Directory search?
A. When you use the Corporate Directory button in order to search, Cisco CallManager does a lookup in the DC directory Lightweight Directory Access Protocol (LDAP) directory. Special characters cannot be parsed correctly and return an error to the IP phone. Some of these special characters are ( & ” ‘ < > ). Avoid use of these characters in the naming convention for your users.
