Your advantages in detail

Looking for a competitively priced phone for your PBX system that offers the same level of comfort as a system phone? Check out the COMfortel 1200 digital system phone: the large illuminated display, hands-free function and direct access to the system’s central phonebook show that convenience is the name of the game. Almost every function of your PBX system can be directly controlled via the phone keys – the current status is indicated by an LED in the respective key.

Details such as InterCom with automatic hands-free talking or the central caller list by group prove highly practical for day-today activities. The same applies to the online name search function (backward search) which shows the caller’s name on the display and as part of the call data listed in the PBX system.

And since it automatically recognises the connection type, the COMfortel 1200 is ready to operate on any S0 or UP0 port of your ICT system immediately.
