For mid-size to large conference rooms, the B189 IP Conference Phone has a sleek and modern design with OmniSound technology to ensure that every individual can be clearly heard. It includes noise suppression filters to virtually eliminate background noise, and offers HD-quality sound for everyone on the call. The full duplex communications offer 360-degree sound pick-up via two speakers and four built-in microphones, meaning that voices can be picked up within a 20-food radius. The five-inch colour touchscreen makes it easy to set up and manage calls, with an intuitive menu that can call, add participants, mute, hold, transfer, and more with ease.
