   Características
This multi-featured, top-of-the-line model supports advanced system functions. The Dialog 4225 Vision is ideal for demanding and executive office usage.

Compared to the Dialog 4223, this telephone features 10 extra programmable keys and a large, six-row, backlit graphical display with three navigation keys and four softkeys. Using the navigation keys in combination with softkeys, users can easily access a display menu with a number of system features such as a phonebook, call list, diversion, absence reason, etc.

An extra high quality hands-free speaking function offering full duplex and Acoustic Echo Canceling (AEC) makes this phone very well-suited for telephone meetings, as well as for conference calls in small meeting rooms.

A headset can be connected directly to the integrated headset port. Toggling between the handset and headset is controlled by a dedicated key. Additionally, up to four extra key panels and an optional unit for external equipment can be easily connected (see “Accessories”).
