Your advantages in detail

The COMfortel D-210 expertly bridges the gap between IP telephony at an entry-level price and a professional range of features that are second to none. This modern IP telephone with its sophisticated design blends in perfectly with modern office environments. The intuitive user interface with illuminated graphic display increases productivity in “day-to-day business”. An all-round visible casing LED ensures that everyone can see you are on the telephone, even if you make calls by using a hidden headset. Incoming calls and missed calls are also displayed conspicuously.

The COMfortel D-210 is scalable and grows with your requirements – it gives you the option of using the phone with its integrated six digitally labelled and freely programmable function keys or upgrading to 66 keys with the COMfortel D-XT20 key extension module. It's ideal for small offices, home offices and call centres.
