Overview

  • An easy-to-use interface that provides a traditional telephony-like user experience
  • Scrollable access to calling features and text-based XML applications
  • Supports either a narrowband or 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
  • 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, 6861 and 6871 models
  • Backlit indicators on the audio path keys (handset, headset, and speakerphone), mute key, select key, line keys and message waiting
  • A volume-control toggle provides easy decibel-level adjustments of the handset, monitor speaker, and ringer
  • 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

Affordable, everyday desktop and wireless (DECT) phones

The Cisco IP Phone 6800 Series multiplatform phones are designed for affordability. They deliver reliable, business-grade audio, with Gigabit Ethernet integration and low power usage.

Ideal for customers with moderate to active VoIP needs, the 6800 Series phones are supported on Cisco-approved third-party unified communications as a service (UCaaS) providers.

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 6841 and 6851 IP phones each have a high-resolution 3.5-inch (396x162-pixel) grayscale display with white backlighting.

The 6800 Series is also energy-efficient and eco-friendly, to support green initiatives. 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 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.
