Everything You Expect From a Modern Phone.

With the new optiPoint 420 family, Siemens is offering a series of highly modern and flexible IP phones that can be modified to suit all requirements. Special features of the optiPoint 420 family include high voice quality provided by the G.722 broadband codec technology. A single-user interface and unrestricted access to wide-ranging and convenient HiPath ComScendo features of HiPath Real Time IP Systems makes telephoning easier and more convenient.

Features also include language selection, optional touch screen module and a JAVA platform.

The modularity and flexible expansion options make the optiPoint 420 phones cost-effective. You pay only for what you really need, and benefit from particularly low operating costs.
