Cisco Headset 561 and 562
Cisco Headset 561 and 562 are two wireless headsets that have been developed for use in today's office. The
Cisco Headset 561 features a single earpiece for extended wear and comfort. Cisco Headset 562 features two
earpieces for use in a noisy workplace.
Both headsets come with either the Standard base or the Multibase for charging your headset, and for monitoring
the headset power level with the LED display. Both bases also displays your call status, such as incoming
call, active call, and calls on mute. If your headset is upgrading the firmware, then the LEDs show the upgrade
progress.
The base connects to the phone using either a USB connector or a Y cable depending upon your phone model
and your personal preference. The Y cable plugs into the AUX and headset ports of the phone.
An AC plug is included for connecting the base to a power outlet. You have to install the power clip for your
region before you can plug in the power adapter.
Occasionally a tone is played over your Cisco Headset 561 or 562. Some of these tones alert you when you
perform an action, such as pressing a button. Other tones warn you that the headset requires attention, such
as when the battery needs recharging, or when you are too far from the base station.
Phone Firmware Release 12.5(1) or later and the defaultheadsetconfig.json file for the Cisco Headset 561 and
562 to function properly with Cisco Unified Communications Manager 12.5(1) or earlier.
