From the customer view in https://admin.webex.com, go to Management > Devices and click the search drop-down to choose a device type.

After you choose Type, the results appear with all the devices in your organization, including headsets.

To narrow down the results even further, you can enter search terms to match specific Cisco headset models—for example, "Cisco 530" or "Cisco 730."

(Optional) Check the check box next to any headset entries that you want to export a local record of, click Export as CSV, check attributes that you want to include, and then click Export.

Click a headset entry to open an overview pane that shows the device status, who it last was connected to, search tags, actions you can take on the device (delete) and further details (connection type, serial number, and software channel).
