The Cisco Unified IP Conference Phone 8831 enhances people-centric communications, combining superior high-definition (HD) audio performance and 360-degree coverage for all sizes of conference rooms and executive offices. It provides an audiophile sound experience with a full-duplex two-way wideband (G.722) audio hands-free speaker.
The IP Conference Phone 8831 is a simple, scalable solution that meets the challenges of the most diverse rooms. It provides flexible deployment options and expansion by using extension microphones that can be wired or wireless (Digital Equipment Cordless Telephone [DECT]) with a daisy-chain configuration of two units.
The IP Conference Phone 8831 has an industrial design with enhanced ergonomics that puts the user first. It offers a detached control panel so that the display may be easily viewed without having to move the entire unit. It also provides easy view of device mute status from all sides.
Supported on Cisco Unified Communications Manager and Business Edition systems, the IP Conference Phone 8831 delivers a more productive, acoustically pleasing, and secure communications experience across sites and participants.
With Cisco Unified IP Conference Phone 8831, your business can benefit from:
- Audio communications support for executive offices and conference rooms up to 1500 square feet (139 square meters) providing 360 degree room coverage*
- Unified Communications delivered from on-premise and hosted Cisco Unified Communications Manager and Cisco Business Edition 6000
- New wired control panel with dial pad that extends from the base station, adding convenience and flexibility in multi-chairperson meetings
- Full-duplex, two-way wideband (G.722), acoustic audio speaker that delivers superior audio performance for a "good as being there" audio experience
- Choice of accessory options with both wired and Digital Equipment Cordless Telephony (DECT) wireless extension microphones and charging stations
Administration and Management:
- Private, highly secure, business audio communications through the 128K Advanced Encryption Standard (AES)
- 10/100 Ethernet port reduces cabling infrastructure and costs with support for collocated PC
- Class 3 Power over Ethernet (PoE) support for infrastructure reduction through elimination of local power cubes
- Configured, deployed, and managed just like other Cisco Unified IP Phones for faster, easier administration
*Larger conference rooms may require daisy-chaining of base units (up to two maximum)
Features and Benefits:
The Cisco Unified IP Conference Phone 8831 offers many improvements over the existing Cisco Unified IP Conference Station 7937G. New features include:

- Expanded room coverage with support for daisy chaining two units
- Support for DECT wireless extension microphones
- Session Initiation Protocol (SIP) signaling
- Device authentication and signaling encryption using Transport Layer Security (TLS) with Advanced Encryption Standard 128 (AES-128)
