Polycom SoundStation 2 conference phone
The president can communicate hands-free on a conference call with other members of the Cabinet, Congress, and other department heads around the country -- and indeed the world, by using the Polycom SoundStation2. It uses high-quality microphones that can pick up voices up to 10-feet away -- which is ideal for the Oval Office or the Situation Room, and includes an LCD display for caller ID and other call information.
