Cisco IP Phone 6821 - VoIP phone with caller ID/call waiting

The 6800 Series combines an attractive, 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 line buttons 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. 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 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.
