The COMfortel D-400 combines the practical design and elegant minimalism of the D series with the functional range of a professional communication solution for the highest demands. This guarantees impressive performance and maximum efficiency in everyday business.
High-resolution 4.3" TFT display with capacitive touch function, HD audio quality thanks to wideband and a headset connection with DHSG/EHS support for free hands when making calls – the COMfortel D-400 leaves nothing to be desired.
For a convenient workflow – even in complex communication structures – the COMfortel D-400 comes with 20 self-labelling and freely programmable function keys including LED signalling, displayed on the screen.
And if that's not enough: The connection of up to three COMfortel D-XT20i extensions and a total of 80 freely programmable keys enables individual adaptation to business requirements. Simple operation at the touch of a button increases productivity and reduces operating costs.
In addition, the COMfortel D-400 also allows contact and calendar data to be synchronized using CardDAV and CalDAV (e.g. Apple® iCloud, Kerio Connect, ownCloud, Radicale, Synology Discstation, Zimbra). The convenient storage of data at an external location not only increases its consistency and security, but also saves a lot of time in daily business.
