Snom D3 Black

The D3 expansion module allows you to extend the function keys of the D3xx phones with USB port and manage a variety of extensions and calls clearly and comfortably. The D3 expansion module features 18 programmable, multicolored LED keys that can be assigned to all functions available on Snom phones. These include line, speed dial, direct dial, extension, presence display, and many more. The multicolored LED keys indicate call and presence status, and the high-resolution display provides a perfect visual interface that can be easily configured and labeled via the phone's web interface or directly on the phone itself. The D3 connects to the phone via a USB cable, and up to three D3 modules can be cascaded for a total of 54 function keys.
