You can upgrade your Cisco Headset 500 Series, Cisco Headset 730, or Cisco Headset USB HD Adapter on Cisco Accessory Hub. This tool enables you to upgrade and check your headset firmware through your web browser. It automatically checks your headset model and current firmware version. It gives you the option to upgrade your headset when there is a newer firmware version available.

You can also upload an older firmware version from your PC desktop. Download the zipped firmware files from the Cisco Software Download page and extract the .ptc firmware files. Headset models match to each .ptc file by name. Use the following table as a guide:

You can only upgrade to new firmware versions from firmware version 2.3(1) or later. You can downgrade from 2.3(1), but Accessory Hub won't be able to detect your headset after it downgrades to the older firmware.
