Enhance User Experience

Get comprehensive and highly secure mission critical Unified Communications features from on-premise or cloud based Cisco communications servers.

With Cisco Intelligent Proximity, share contact lists and call history, and move the audio path of active voice and video calls from your smartphone and tablet** to the 8851, when in range of the desk phone.

Charge your personal smartphone with USB.

Get exceptional clarity in voice communications, however you wish to communicate. The 8851 phone offers high-quality, full-duplex, wideband (G.722) audio with superior echo cancellation on third-party headsets, the handset, and speakerphone.

Navigate menus more easily with a five-way navigation cluster. Recognize displayed content at a glance, under a variety of lighting conditions. The 8851 model offers a high-resolution, five-inch, widescreen backlit VGA (800 x 480 pixel) color display.

Increase responsiveness and productivity by adding more shared lines, speed dials, and custom feature keys, with support of up to two optional key expansion modules (available CYQ3 2014).

Easier and Cost Effective Administration

Consolidate administration of software updates with IP phone firmware common to both Cisco IP Phone 8800 Series and Cisco 7800 IP Phone Series models.

Help reduce energy costs and carbon footprint in off-work hours, without the need for IT intervention, with Cisco EnergyWise options.
