• Dolby Conference Phone

    • The Dolby Conference Phone intelligently adapts to your environment to deliver excellent sound. Its dynamic leveling technology adjusts to a variety of room and participant scenarios, so people can speak more naturally. Paired with Dolby Voice software from leading service providers, it provides stunning audio for more productive meetings.

    • Excellent audio for video meetings and conference calls

    • Benefits of the Dolby Conference Phone

      • Automatically adjusts to people and places

        Full-room pickup captures near and distant voices, and even overlapping speech, for more natural conversation. Dynamic leveling distinguishes between talkers and background noise, and boosts the sound of quiet or distant voices to help everyone be heard, even in rooms with poor acoustics.

      • Dolby Voice service for further enhanced audio

        Adding Dolby Voice® enabled service from leading providers makes the audio quality even better by giving participants the benefit of voice placement: each speaker's voice is presented from a distinct location, making it easier to follow the conversation and focus on the business at hand.

      • Simple user experience in a streamlined design

        Intuitive touch-screen controls and customizable apps make it easy to start, join, and run meetings, so you can get down to business more quickly. The Dolby® Conference Phone can even serve as your single interface for audio conferencing, video conferencing, and screen sharing.

      • Easier for IT to deploy, control, and manage

        Intelligent hardware design, automated deployment tools, and an app library for leading service providers simplify IT tasks. In addition, the phone is a dual-mode device — an endpoint for Dolby Voice enabled services as well as a SIP conference phone for IP telephony.

    • Introducing Dolby Voice Room

      Our new video conferencing hardware solution intelligently adapts to lighting, motion, acoustics, and voices to give everyone an amazingly natural meeting experience.

      • Conference phones can do better — much better — and finally the Dolby Conference Phone delivers, raising expectations for audio quality in business conferencing, across all kinds of rooms, with a dramatically better experience for participants and IT alike.

        Audio that intelligently adapts

        Meeting participants get excellent sound, combined with a best-in-class ability to pick up everyone's voice, even in rooms with poor acoustics. Dynamic leveling continuously maps the room, canceling out noise, and boosting the sound of quiet or distant talkers to help everyone be heard — even when conversations overlap.

        Enhanced audio with Dolby Voice

        When used with a Dolby Voice enabled service from leading service providers, the Dolby Conference Phone gives you even better audio, including voice placement, which presents each speaker's voice from a distinct location, making it easier for everyone to follow the conversation.

        Easy meeting management, elegant design

        Participants get a user-friendly device with an intuitive touch-screen interface to start, join, and manage meetings. The phone's elegant modern design complements today's huddle spaces, conference rooms, boardrooms, and executive offices.

        Engineered with IT in mind

        The Dolby Conference Phone offers intelligent hardware design and automated deployment tools for easier setup and provisioning. Remote device management with the Dolby Conferencing Console simplifies monitoring, diagnostics, and control, saving IT time. Leading collaboration services can load preconfigured apps onto the phone's UI for seamless integration.

        Supports standard IP telephony

        As a dual-mode device, the phone acts as an endpoint for Dolby Voice enabled services and a SIP conference phone for IP telephony, compatible with both a new installation and a legacy system.
