D7 IP add on module 18 buttons

The D7 expansion module features 18 multi-color LED keys which can be programmed with all functions available known from snom phones. The high-resolution display provides a perfect visual interface which can be easily configured and labelled via the phone’s web interface or directly on the phone itself. Using the D7 could not be easier: simply connect the USB cable and it’s ready to use. Three D7 expansion modules can be daisy-chained to add up to 54 function keys to your phone. The D7 is the perfect addition to any snom 7-series desk phone.
