Whether in a small executive office or a large boardroom, this device ensures clear, reliable audio through its advanced wideband technology and 360-degree coverage. By focusing on both acoustic performance and user-friendly ergonomics, it helps teams collaborate more effectively across different locations.
The system is built to be flexible and scalable, allowing organizations to adapt the hardware to their specific room requirements. It integrates seamlessly with Cisco Unified Communications Manager and Business Edition systems, ensuring that businesses can maintain secure and productive communication workflows. With its industrial design and intuitive control panel, the 8831 series simplifies the conferencing experience while maintaining a professional aesthetic.
Product overview
The core of the Cisco Unified IP Conference Phone 8831 is its ability to deliver an audiophile-grade sound experience. It features a full-duplex, two-way wideband speakerphone that captures the full voice spectrum, ensuring that speech is clear and natural. The device is engineered with a detached control panel, which allows users to view the display and manage calls without needing to reposition the entire unit, enhancing both convenience and usability.
Scalability is a key strength of this product line. Users can expand the system’s reach by adding optional wired or wireless DECT extension microphones, or by daisy-chaining two base units together to accommodate larger meeting spaces. The product is available in various configurations, including standard base units and specialized kits for daisy-chaining, as well as versions tailored for third-party SIP-based call control platforms. Additionally, the phone supports a wide range of accessories, such as dedicated wireless microphone kits, spare batteries, and various power cord options to suit global deployment needs.
