Reverse Name Lookup for Incoming and Outgoing Calls
Reverse name lookup searches for the name of a number in an incoming, outgoing, conference, or transferred
call. The reverse name lookup acts when the phone cannot find a name using the service provider directory,
Call History, or your contacts. Reverse name lookup needs a valid LDAP Directory or XML Directory
configuration.
The reverse name lookup searches the phone's external directories. When a search succeeds, the name is
placed in the call session and in the call history. For simultaneous, multiple phone calls, reverse name lookup
searches for a name to match the first call number. When the second call connects or is placed on hold, reverse
name lookup searches for a name to match the second call.
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
