The Cisco® IP Phone 6800 Series with Multiplatform Phone (MPP) Firmware is a cost-effective, high-fidelity voice communications portfolio designed to improve your organization’s person-to-person communications while reducing your operating costs on approved Unified- Communications-as-a-Service (UCaaS) platforms.

The 6800 Series combines an attractive, new ergonomic design with ΓÇ£always-onΓÇ¥ reliability and secure encrypted communications. The phones deliver advanced IP telephony features and wideband audio capabilities with an easy-to-use, full-featured voice communications experience.

The line buttons on each model are fully programmable. You can set up line buttons to support either SIP registrations, or call features, such as speed dialing. You can also boost productivity by handling multiple calls for each SIP registration, using the multiple-calls-per-line appearance feature. Tricolor LEDs on the line buttons support the calling features and make the phone simple to use.

Fixed function buttons on the 6800 series phones give you one-touch access to service, messaging, directory, hold/resume, transfer, and conference features. A full-duplex speakerphone lets you set up clear multiparty conferences for flexible, productive collaboration. The 6800 series provides exceptional noise isolation when used with a Cisco 500 Series Headset.

The Cisco IP Phone 6800 Series maintains the same usability standards and standards for a context-sensitive user experience as the Cisco IP Phone 7800 Series. The 6821 IP phone has a 2.5-inch (240x120-pixel) grayscale display with white backlighting for easy reading.

The 6800 Series is also energy-efficient and eco-friendly, to support green initiatives. The 6821 and 6851 support Power over Ethernet (PoE) Class 2.
