Cisco 6821 IP Phone
The Cisco 6800 Series provides both an attractive, ergonomic design with "always-on" reliability and secure encrypted communications. This phone delivers 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 dialling. You can also boost productivity by handling multiple calls for each SIP registration, using the multiple-calls-per-line appearance feature. LED's 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.
