## Long description

The Cisco IP Phone 6821 is a compact, two-line business telephone in black designed for IP-based voice communications on approved UCaaS platforms. It features a 2.5-inch (240 x 120 pixel) grayscale display with white backlight, a wired handset, integrated full-duplex speakerphone, and support for common voice codecs to deliver clear audio in office environments. The phone offers programmable line buttons with tricolor LEDs, fixed-function keys for messaging, directory, hold, transfer and conference, and energy-efficient operation with Power over Ethernet (PoE) support.
Advantages
The 6821 provides a straightforward user experience with context-sensitive controls and programmable line buttons that support SIP registrations or call features such as speed dial. Wideband audio and support for common codecs ensure good voice quality while the full-duplex speakerphone and headset compatibility improve multiparty call clarity. The device is energy-efficient, supports PoE Class 2, and includes secure, encrypted communications when deployed on supported multiplatform call-control systems.
Suitable for
Small and medium offices needing a basic two-line IP desk phone
Reception or shared workspaces where compact form factor is preferred
Environments requiring PoE deployment to avoid separate power adapters
Users who need simple access to messaging, directory, hold, transfer and conference functions
When it may not be suitable
This model is not suitable for users who require a touchscreen interface or extensive programmable line capacity beyond two lines. It also lacks advanced colour display features and may not meet needs for phones requiring integrated video or large-screen applications.

How to use
Connect the phone to your Ethernet network and power it via PoE or an approved power adapter.

Use the programmable line buttons and fixed-function keys for calls, messaging, directory lookup, hold, transfer and conference operations. Adjust volume using the digital volume control and use a compatible Cisco headset for improved noise isolation during calls.
What to consider before purchase
Confirm compatibility with your UCaaS or call-control platform and provisioning method
Decide whether a two-line device meets your concurrent call and line appearance needs
Check that PoE infrastructure is available if you prefer not to use a power adapter
Ensure required codecs (for example G.711 or G.729) are supported by your telephony service
Usage recommendations
For reliable voice quality, deploy the Cisco 6821 on a managed LAN with QoS enabled, use PoE for clean power delivery, and pair with a Cisco 500 Series headset when consistent noise isolation is required.
