Designed for voice communication over analog telephone lines, it provides a clear, easy-to-read screen and basic call control functions in a compact, black housing.

Programmable function keys and LED signalling allow customization of frequent tasks and fast access to important features. The black finish and compact footprint suit professional workspaces where a durable analog telephone is required.
Connect the COMfortel D-400 to an analog telephone outlet and plug in the wired handset. Use the TFT display to view caller information and navigate basic menu options. Assign frequently used functions to the programmable keys for direct access. If additional key capacity is needed, connect supported extension modules according to the manufacturer instructions. Configure contact and calendar synchronization through compatible CardDAV/CalDAV services if required for your workflow.
Place the telephone on a stable desk surface near an analog wall socket and away from strong electromagnetic sources. Regularly update contact synchronization on supported external services to keep caller lists and calendar entries consistent. Use the programmable keys to reduce repetitive dialing and improve daily efficiency.
