Dolby Voice Conference Phone

Built for Better Conference Calls

The Dolby® Voice™ Conference Phone is an innovative device that brings the Dolby Voice conferencing experience to the meeting room.

It dramatically improves meetings by bridging the gap between in-room and remote participants, letting everyone understand what's being said, easily determine who said it, and participate as if they are all in the same room.

Built for Better Conference Calls

We designed the Dolby Voice Conference Phone to deliver the Dolby Voice experience, not as just another conference phone. An integral component of the Dolby Voice solution, it offers stunning audio quality and easy joining and management of meetings, features that promote productive conferencing.

Superior Sound

With wideband audio and effective noise suppression, the Dolby Voice Conference Phone picks up and clearly presents voices in the room, making it easy for everyone on the call to differentiate who's talking. Remote participants feel like a part of the in-room conversation.

Touch-Screen Interface

Easily connect to and manage meetings, know who's on the line, and access all of the phone's capabilities.

Dual-Mode Device

Uniquely, it's both an IP telephony endpoint and a Dolby Voice device.

Bring Remote Attendees into the Conference Room

Meetings frequently bring together remote attendees and participants who gather in a central location. The Dolby Voice Conference Phone brings everyone into the conversation, extending the Dolby Voice experience to in-room and remote participants alike.

Remote attendees will feel just as if they're in the room. They will clearly hear—and differentiate—everyone. Participation will increase, and so will productivity.

Superior audio performance

The Dolby Voice Conference Phone picks up all voices in the room and sends a clean wideband feed, free from background noise. Its unique voice-separation capability lets you hear each person's voice from a distinct virtual location. Remote and in-room participants can clearly understand and distinguish who's speaking, keeping the flow of conversation going.

Elegant design

The phone's clean, modern lines and touch-screen interface reflect its advanced capabilities.

Exceptionally easy to use

Easily connect to and manage meetings with the touch-screen user interface. See who is in the meeting, control disruptions, and spend more time discussing, rather than just getting online. You can also easily access traditional phone features.

Supports Standard IP Telephony

The Dolby Voice Conference Phone is a dual-mode device: an endpoint for Dolby Voice enabled services and a SIP phone for IP telephony environments.

Meets IT and Administrative Needs

The Dolby Voice Conference Phone includes capabilities for provisioning, management, security, and directory functions to meet the needs of IT.
