Features

Hardware Features

Ergonomic design

●

The phone offers an easy-to-use interface and provides a traditional telephony-like user experience.

Graphical display

●

White backlit, greycale, 396×162 pixel-based display (3.5”) provides scrollable access to calling features and
text-based XML applications.

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 like speed dialing. You can also boost productivity by handling multiple calls for each
directory number, using the multi-call per-line appearance feature. Tri-color LEDs on the line keys support this
feature and make the phone simpler and easy 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 multi-party conferences for
flexible, productive collaboration.

The Cisco® IP Phone 7800 Series sets a new standard in usability and delivers a context-sensitive user

experience. It features a high resolution 3.5” (396x162) greyscale display, with white backlighting for easy reading.

Localized language support, including right-to-left onscreen text, meets the needs of global users.
The Cisco® IP Phone 7800 Series is also more energy-efficient and eco-friendly, to support your green initiatives.

Each phone supports Power-over-Ethernet (PoE) Class 1 and Cisco’s EnergyWise™, and is Energy Star certified.
A standard power-save option reduces power consumption during off-hours, to save money and maximize energy
efficiency.

The IP Phone 7800 Series portfolio is ideal for any mid-sized to large enterprise company that wants to update its
phone system from a traditional analog or digital-based system to an IP Communications system. It’s also an
excellent choice if you’re seeking to expand your voice communications support with your current Cisco Unified
Communications solution.
