Matrix ETERNITY NE System Manual 401
Call Duration Display
What's this?
By invoking Call Duration Display, extension users can view the duration of the current call instantly. 
Needless to say, only DKP and Extended IP Phone users can view Call Duration Display. The system displays the 
duration of the current call on the LCD display of the phone.
The current call may be incoming or outgoing, internal or external call.
How it works
• The DKP/Extended IP Phone user goes OFF-Hook
• Dials an external number.
• The remote party answers the call.
• The dialed external number with duration (5-digits in the format of MM:SS) is displayed on the LCD of the 
phone, when the call is answered.
