You can use the Cisco Wireless IP Phone 8821 and 8821-EX Desktop Charger to charge your phone and spare phone battery. The charger works on AC power or from a charged spare phone battery. It can be secured with a standard laptop cable lock.

If your phone has a protective case, you don't need to remove the case before you charge the phone in the desktop charger. You adapt the charger to fit the phone.

You can use a USB to Ethernet adapter (dongle) to connect the desktop charger to the Ethernet for only automatic Wi-Fi profile provisioning and certificate enrollment purposes. You cannot use the dongle to make voice calls over the Ethernet.

Built in Speakerphone

The charger includes a speakerphone that you can use while the phone is docked. Use the phone volume buttons to control the speakerphone volume, and the Mute button on the charger itself. When the speakerphone is muted, the Mute button lights red.

Phone Charging Indicators

When you put the phone into the charger, the phone indicates that the battery is charging with the red LED on the top of the phone. If the phone is turned on when you put it into the charger, you see a message on the screen. If the phone is turned off or the battery is too weak, you see an icon displayed on the screen.

Spare Battery Charging Indicators

Spare batteries can be charged with the additional charging port behind the main phone charging port. When you put a spare battery into the charger, the Battery LED (to the right of the phone) lights to show the charging status;

• Red Light - Spare Battery is Charging
• Green Light - Spare Battery is fully Charged
