Cisco Unified IP Conference Phone 8831

Product Overview

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.

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:

●Superior wideband acoustics with the first two-element speaker in a conference phone; this feature allows the phone to capture the full voice spectrum without having to compromise with a single-element speaker

●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)

●Media encryption using Secure Real-Time Transport Protocol (SRTP) with AES-128

Directories	The Cisco Unified IP Conference Phone 8831 identifies incoming messages and categorizes them for users
	on the screen. This feature allows you to quickly and effectively return calls using direct dial-back capability.
	The corporate directory integrates with the Lightweight Directory Access Protocol Version 3 (LDAPv3)
	standard directory.
Settings	The Settings feature key allows you to adjust display contrast, select background images (if available), and
	select from a large number of unique ringer sounds through the User Preference menu. Network
	configuration preferences also can be set up (usually by the system administrator). Configuration can be
	either automatically or manually set up for Dynamic Host Control Protocol (DHCP), Trivial File Transfer
	Protocol (TFTP), Cisco Unified Communications Manager, and backup Cisco Unified Communications
	Manager instances.
Help	The online Help feature gives you information about the phone keys, buttons, and features. The pixel display
	allows for more flexible feature navigation and significantly expands the information viewed when using
	features such as Services, Information, Messages, and Directory. For example, the Directory button can
	show local and server-based directory information.
Hold, Mute, and Redial keys	The Mute key is a fixed key. When it is active, the LED flashes on the Cisco Unified IP Conference Phone
	8831 as well as on the optional wired and wireless microphone kits. Hold and Redial are provided as soft
	keys associated with the screen, and are always at the same position for easy access.
Display	The conference station has a large high-resolution, graphical 3.5-inch backlit display (396 x 162 pixels).
Speakerphone	The Cisco Unified IP Conference Phone 8831 offers full-duplex high-quality wideband speakerphone
	technology. Included are Automatic Gain Control, comfort-noise generation, silence suppression and voice
	activity detection, Echo Suppression, and dynamic noise reduction, which reduces noise by up to 9 dB from
	constant noise sources such as fans or heating, ventilation, and air conditioning (HVAC) systems.
	A two-way high-fidelity loud speaker system provides superior speech clarity versus traditional conferencing
	systems.
Volume control	The convenient Volume Control buttons on Cisco Unified IP Conference Phone 8831 provide for easy,
	decibel-level adjustments for the speakerphone and ringer.

Quality-of-service (QoS) options The Cisco Unified IP Conference Phone supports DHCP and 802.1Q/p standards. The conference station can also be configured with an 801.1Q VLAN header containing the VLAN ID overrides configured by the Admin VLAN ID.

Multiple ring tones	User-adjustable ring tones are available.
Security	The Cisco Unified IP Conference Phone 8831 supports device authentication through 802.1.x supplicant
	(TLS) and SRTP.
