The Cisco® IP Phone 6800 Series with Multiplatform Phone (MPP) Firmware is a cost-effective, high-fidelity voice communications portfolio designed to improve your organization’s person-to-person communications while reducing your operating costs on approved Unified- Communications-as-a-Service (UCaaS) platforms.

The 6800 Series combines an attractive, new ergonomic design with “always-on” reliability and secure encrypted communications. The phones deliver advanced IP telephony features and wideband audio capabilities with an easy-to-use, full-featured voice communications experience.

The Cisco IP Phone 6800 Series provides four phone models (and an optional Key Expansion Module) to the Cisco Multiplatform Phone (MPP) portfolio (Figure 1):

     Cisco IP Phone 6821 with Multiplatform Firmware, supporting two SIP registrations

     Cisco IP Phone 6841 with Multiplatform Firmware, supporting four SIP registrations

     Cisco IP Phone 6851 with Multiplatform Firmware, supporting four SIP registrations

     Cisco IP Phone 6861 with Multiplatform Firmware, supporting four SIP registrations

Notes:
Only the 6851 supports the Key Expansion Module (KEM).

6861 supports Wi-Fi function.

The Cisco IP DECT 6800 Series with Multiplatform Firmware has its own datasheet: https://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/ip-dect-6800-series-multiplatform-firmware/datasheet-c78-741764.html

Cisco IP Phone 6800 Series product overview

The line buttons on each model are fully programmable. You can set up line buttons to support either SIP registrations, or call features, such as speed dialing. You can also boost productivity by handling multiple calls for each SIP registration, using the multiple-calls-per-line appearance feature. Tricolor LEDs on the line buttons support the calling features and make the phone simple to use.

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. 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 6821, 6841, 6851 and 6861 are Energy Star certified. The 6841 6851 and 6861 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.

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.

The 6800 KEM comes with a foot stand and cable to connect it directly to the base device in a traditional side-by-side configuration (Figure 2).

Table 1.             Cisco IP Phone 6800 Series features and benefits

Feature

Benefits

Hardware features

Ergonomic design

  An easy-to-use interface that provides a traditional telephony-like user experience.

Graphical display

  6821: White backlit, grayscale, 2.5-in. (6.4-cm) 240 x 120-pixel display.
  6841 and 6851: White backlit, grayscale, 3.5-in. (9-cm) 396 x 162-pixel display.
  6861: White backlit, grayscale, 3.2-in. (8.1-cm) 320 x 120-pixel display.
  Scrollable access to calling features and text-based XML applications.

Handset

  6821: Supports a narrowband audio handset connected through an RJ-9 port.
  6841 and 6851: Supports either a narrowband or a wideband audio handset connected through an RJ-9 port.
  6861: Supports a wideband audio handset connected through an RJ-9 port.
  All 6800 series handsets are Hearing-Aid-Compatible (HAC) and meet Federal Communications Commission (FCC) loudness requirements for the Americans with Disabilities Act (ADA). You can meet Section 508 loudness requirements by using industry-standard inline handset amplifiers such as Walker Equipment W-10 or CE-100 amplifiers. The dial pad on all 6800 series models is also ADA-compliant.
  The 6800 series handsets produce a magnetic field that attracts small metallic objects such as pins and staples. To avoid possible injuries, do not keep small metallic objects close to the handset.

Headset

  The 6800 series provides exceptional noise isolation when used with a Cisco 500 Series Headset
  The analog headset jack is a wideband-capable RJ-9 audio port for the 6821, 6841, 6851 and 6861 models. For more information about Cisco’s headset offer: https://www.cisco.com/c/en/us/products/collaboration-endpoints/headset-500-series/index.html

Backlit indicator

  6821: Backlit line buttons and a message waiting indicator; uses icons on the LCD to indicate activation of the headset, mute, and select buttons.
  6841 6851 and 6861: Backlit indicators on the audio path buttons (handset, headset, and speakerphone), select, line, and message waiting buttons.

Volume control

  A volume-control toggle provides easy decibel-level adjustments of the handset, monitor speaker, and ringer.

Full-duplex speakerphone

  A full-duplex speakerphone gives you flexibility in placing and receiving calls. For added security, the Audible Dual-Tone Multi-frequency (DTMF) tones are masked when the speakerphone mode is used.

Single-position foot stand

  The foot stand holds the phone in a single position, making the display easy to view and the buttons easy to use while sitting down. You can remove the foot stand for wall mounting. There are mounting holes located on the back of the phone.

Wall-mountable

  6821: Can be mounted directly to the wall using woodscrews and anchors for drywall.
  6841 6851 and 6861: Can be wall-mounted using the optional 6800 Series wall-mount kit (sold separately).
