Even the entry-level model COMfortel D-100 is packed with professional features such as self-labelling function keys including LED signalling, context-sensitive soft keys and a headset connection for cordless headsets with Electronic Hook Switch (EHS). Additionally, the intuitive user interface with its illuminated black-on-white graphic display visibly improves day-to-day productivity.


Just like its bigger brothers, 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. Its functional design looks impressive in any modern office environment. All this makes the COMfortel D-100 perfect for small offices, home offices and call centres.
