Snom D3 Expansion module

The Snom D3 is the optimal expansion module for the Snom D3xx series desk phones with USB connection.

The expansion module allows users who make a lot of calls greater flexibility and productivity by providing 18 programmable LED function keys with features such as line hold, speed dial, extension and presence indication.

The Snom D3 with its high-resolution black-and-white display can be easily connected via plug-and-play using a USB cable. Up to three extension modules can be connected in series to expand the range of functions enormously. This provides up to 54 additional function keys.

The keys can be assigned with all functions available on the Snom phones, e.g. short and direct dial or extension. The multicolour LEDs indicate the call and presence status of a direct dialling.

The monochrome display offers excellent contrast and visibility in all lighting conditions.

If you really need a lot of programmable function keys, the Snom D3 is just right for you, because you can connect up to 3 in a row to each Snom desk phone.
