BusinessPhone – Cordless DT412/DT422/DT432 40
System Phonebook
Compared to the “ Integrated Phonebook ” on page 35 which is a
cordless phone specific function, the System Phonebook is stored
in the BusinessPhone the system.
The System Phonebook covers internal directory numbers as well
as external common abbreviated numbers.
As the System Phonebook is available for several telephone types
the access as well as the navigation within the Phonebook is kept
generic which means it will be controlled via the normal keypad.
If you prefer the handling via the menu- and navigation keys please
contact your administrator to setup a company Phonebook on your
cordless phone.
