Your advantages in detail

Using the COMfortel 1600 is a real pleasure, not only thanks to its convenient control options and intuitive menu design, but also because of its ergonomically optimised adjustable support feet. Its backlit touch display makes it easier to use the keyboard and directional pad to select functions directly. Wherever an ISDN system phone has to meet the highest standards, in a hotel, an office or at home, the COMfortel 1600 is the one you need: it has a multitude of functions that make telephoning more convenient.

Its internal telephone book has space for 1,600 telephone numbers, its sophisticated audio components achieve excellent acoustic properties and there's even a separate socket for not cordless headsets. The monochrome graphical touch display, which also has an reverse display option, enables you to control your PBX from your desk, quickly and intuitively. You can even programme every function key separately. The intelligent power management function which, among other things, automatically switches off the display back-light and LEDs, is very impressive.
