The Dolby Conference Phone is provided with multiple microphones and high-performance software. All speakers can be clearly heard and listeners can differentiate distinctly between the points in the room from where each voice emanates. The round, perforated metal cover with its concave centre ensures complete detection of all contributions in the room and also issues a cue for participation in the discussion. The user interface with touch screen is intuitively operated. A clearly visible bright light ring displays the call status.
