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” (396×162) greyscale display, with white backlighting for easy reading. 

Localized language support, including right-to-left onscreen text, meets the needs of global users.
