Description

Cisco 8831 Unified IP Conference Phone — Full-Duplex Wideband Audio

The Cisco 8831 is a professional IP conference phone designed to deliver crystal-clear, 360-degree room coverage for small to medium meeting rooms. Its full-duplex wideband audio engine eliminates the awkward half-duplex interruptions of lower-end conference phones, while the scalable microphone system lets you add wired or wireless extension mics for larger spaces. Compatible with Cisco Unified Communications Manager and Business Edition systems. Backed by a 3-month Reboot IT warranty and free standard AU shipping.

Key Benefits

  • Full-duplex wideband audio — Natural, simultaneous two-way conversation without audio cutoff, delivering G.722 wideband clarity that makes remote participants feel present in the room
  • 360-degree microphone coverage — Omni-directional pickup captures voices from all directions around the table, ensuring all participants are heard clearly without repositioning the unit
  • Scalable microphone expansion — Add wired or wireless extension microphones (sold separately) or daisy-chain two 8831 units together to cover larger boardrooms and training rooms
  • Ergonomic attached control panel — The display and controls are easily viewed and operated without moving the base unit, keeping the table setup clean during active meetings
  • PoE powered simplicity — Single Ethernet cable handles both network connection and power delivery via PoE 802.3af, eliminating the need for a separate power outlet at the conference table
  • Cisco UC integration — Deep integration with Cisco Unified Communications Manager and Business Edition for directory access, call history, and unified communications features

Performance in Meeting Rooms

The 8831 excels in dedicated meeting rooms and boardrooms where call quality directly impacts collaboration outcomes. The full-duplex engine means participants at both ends can speak simultaneously without audio clipping — a critical difference versus budget conference phones during fast-moving discussions. The wideband G.722 codec, where supported by your phone system, delivers noticeably richer voice quality than standard-band alternatives.

For larger rooms, the extension microphone system is genuinely useful — a single daisy-chained wired mic extends coverage to the far end of a long boardroom table without introducing audio lag or quality degradation. The unit's low-profile design keeps sightlines clear across the table during face-to-face and hybrid meetings.

Note: Power adapter is not included. Unit requires PoE 802.3af from a compatible switch or a separate Cisco power adapter. The 8831 is designed for Cisco CUCM environments.

Frequently Asked Questions

Does the 8831 require a Cisco phone system?

Yes — the 8831 is designed for Cisco Unified Communications Manager (CUCM) and Business Edition systems. Third-party SIP compatibility depends on firmware configuration.

Is a power adapter included?

No. The 8831 is powered via PoE 802.3af from a compatible network switch, or a separate Cisco power adapter is required.

Can I expand the microphone coverage for a large room?

Yes — wired and wireless extension microphones (sold separately) can be connected to extend coverage. Two 8831 units can also be daisy-chained for very large conference spaces.

What is wideband audio and why does it matter?

Wideband (G.722) captures a broader voice frequency range than standard telephony, making voices sound more natural and reducing listener fatigue during long conference calls.

Does free shipping apply to this product?

Yes — free standard AU shipping applies to this item.
