The Ericsson Dialog 4222 is the second model up in the Dialog 4000 range of digital telephones. All the Dialog phones will work with the majority of Ericsson systems including the Ericsson MX-ONE, MD110 BC12, and the MD110 BC11 telephone systems. If you are not sure what your system is though a quick way to find out is by looking at what you existing phones are, if they are either the Ericsson Dialog 4220, 4222, 4223, or 4225 then it will be fine.
The Ericsson Dialog 4222 Office telephone also has a LCD screen that shows the incoming callers number, as well as the clock and calendar. It also has a full handsfree speaker as well so you can talk to the other party without having to lift up the receiver.
Headset compatibility is something that more and more users are looking for in a system telephone. The Ericsson 4222 Office has a separate headset port to enable the user to connect a headset into.
The Ericsson 4222 Office telephone also has 5 programmable keys that can be set to access specific features making every day use much easier. It is available in both Light and Dark Grey so it will blend into any office environment.
