Cisco IP Phone 6800 Key Expansion Module product overview
The Cisco IP Phone 6800 Key Expansion Module (KEM) extends the capabilities of the Cisco IP Phone 6851 with additional buttons. This module adds 14 physical buttons along with access to 14 additional buttons via the page buttons, for a total of 28 additional buttons. The KEM supports the Programmable Line Key (PLK) function, but does not support any SIP registrations. Calls may be monitored and answered using the PLK function, but calls may not initiated from the KEM. The 6851 IP phone supports one KEM only.
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 6861 has a 3.2-inch (320x120-pixel) LCD. The 6841 and 6851 IP phones each have a high-resolution 3.5-inch (396x162-pixel) grayscale display with white backlighting. The 6871 IP phone has a high-resolution 3.5-inch (480x272-pixel) color LCD. Localized language support is available for global users. See Table 6 for a list of available languages.
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. The 6871 supports Power over Ethernet (PoE) Class 3. The 6821, 6841, 6851, 6861 and 6871 are Energy Star certified. The 6841, 6851, 6861 and 6871 support a power-save option that reduces power consumption during off-hours, saving costs by increasing energy efficiency.
The 6861 phone is Wi-Fi enabled phone in 6800 series. It supports built-in dual band Wi-Fi up to 802.11n. Also provides reliable wireless connection and convenient connection to access point via WPS (Wi-Fi Protected Setup).
The 6800 Series is ideal for businesses that want to update their phone systems from traditional analog or digital-based systems to an IP communications system with supported multiplatform call control systems.

 |
| Backlight display A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light themselves - unlike for example Cathode ray tube (CRT) displays - they need illumination (ambient light or a special light source) to produce a visible image. Backlights are used in small displays to increase readability in low light conditions such as in watches, and in computer displays and LCD televisions to produce light in a manner similar to a CRT display. |
