How to configure 
For this feature to work, the following must programmed: 
• DSS Key: A direct station selection (DSS) key must be programmed for the Dial by Name feature. Without 
the DSS Key this feature will not be accessible. 
Both EON48 and SETU VP248, the Extended IP Phone, have the DSS Key labeled as 'Names'.
• Global Directory: The names of the external parties must be programmed against their respective 
telephone numbers in the directory. Refer the topic “Abbreviated Dialing” for instructions on programming 
the Global Directories.
• Personal Directory: The names of the external parties must be programmed against their respective 
telephone numbers in the Personal Directory. Refer the topic “Abbreviated Dialing” for instructions on 
programming the Personal Directories.
The Personal Directory must be assigned to the Extensions. 
• Extension Names: Extensions may be SLTs, DKPs, SIP extensions. Refer “Extension Numbering Plan” 
under Basic Settings for instructions on assigning names to extensions. 
• Class of Service: Dial By Name is allowed to all DKP and Extended IP Phone users. However, the use of 
this feature is related to the following features, which must be enabled in the Class of Service of the DKP 
and SIP extension users: 
• 'Internal Calls'- This is to be enabled so that the extension can call other extensions.
• Global Directory Part 1
• Global Directory Part 2
• Global Directory Part 3.
Global Directory Part 1 is assigned to all extension by default. 
If you want the names to be drawn from Global Directory Part 2 and Part 3, provided these are 
programmed, you must enable these two directories in the COS of the DKP and SIP extensions. See 
“Class of Service (COS)” for instructions.
The system will display the names exactly as they have been programmed in the Personal and Global 
Directories.
