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.

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).
