The Polycom SoundStation 2W conference phone is compatible for use on any analogue telephone line or analogue extension. It is the SoundStation 2W's DECT base unit that connects directly to the analogue telephone line.
Also included is a Skype cable, that offers a secondary connection option. The Skype cable connects the SoundStation 2W conference system into the soundcard connection port of a computer. This means that calls can be made over the computer line instead of the telephone line and because it bypasses the charges imposed by telephone companies, calls made this way are usually free.
