The Cisco IP Phone 6851 is a cost-effective, high-fidelity voice communications phone designed to improve your organization’s people-centric communications while reducing your operating costs in third-party hosted call control deployments. The phone delivers advanced IP telephony features and wideband audio capabilities with an easy-to-use, full-featured voice communications experience on third-party hosted call control.

Description

**PLEASE NOTE - This is a SIP phone which forms part of Cisco's Multiplatform series and does not work with Cisco Call Manager**

The line keys on each model are fully programmable. You can set up keys to support either lines, such as directory numbers, or call features, such as speed dialing. You can also boost productivity by handling multiple calls for each directory number, using the multiple-calls-per-line appearance feature. Tricolor LEDs on the line keys support this feature and make the phone simpler to use.

Fixed function keys on all models 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 Cisco IP Phone 6800 Series maintains the same usability standards and context-sensitive user experience as the Cisco IP Phone 7800 Series. The 6851 IP phone features a high-resolution 3.5-inch (396x162-pixel) grayscale display with white backlighting for easy reading. Localized language support, including right-to-left onscreen text, meets the needs of global users.

The 6800 Series is also more energy-efficient and eco-friendly, to support your green initiatives. The 6851 IP phone supports Power over Ethernet (PoE) Class 2 and is Energy Star certified, with a standard power-save option available to reduce power consumption during off-hours, saving money and increasing energy efficiency.
