/mcpStep 3 Check the Cisco Headset Service check box from the CM Services section and select Save. What to do next Prepare your Headset COP Files. Prepare Your Headset COP Files You can install and upgrade the latest headset firmware using a COP file. A headset COP file contains all the firmware versions of different headset or accessories models along with their configuration data. Ensure that the Cisco Headset service is up and running before the COP file is installed. Ensure that the headset COP file is installed on all nodes of Unified Communications Manager. Note 1. Install or upgrade the COP file to the Unified Communications Manager system before you can start using your Cisco headsets or accessories. When you connect your headset or accessories to the endpoints, the headset and accessories template configuration changes are applied. If you make any updates to the headset and accessories template configurations on Unified Communications Manager, the endpoints apply these configuration updates on the connected headsets or accessories. All configuration updates depend on the version of the headset and accessories template in the COP file. If the headset and accessories template version is higher in the latest COP file, the configuration file on Unified Communications Manager is updated. If the configuration file in the COP file is upgraded, the headset and accessories template version in Unified Communications Manager is updated irrespective of the version of the template and vice versa. The following list shows the various template version update scenarios after a COP file upgrade: • If the Unified Communications Manager is currently installed with the headset and accessories template version 1-10 and you upgrade your Unified Communications Manager server that has headset and accessories template version 1-12, then the chosen headset and accessories template version is 1-12. Unified Communications Manager opts for the higher headset and accessories template version. • If the Unified Communications Manager is currently installed with the headset and accessories template version 1-10 and you upgrade your Unified Communications Manager server that has headset and accessories template version 1-9, then the chosen headset and accessories template version is 1-10. Unified Communications Manager opts for the higher headset and accessories template version. • If the Unified Communications Manager is currently installed with the headset and accessories template version 1-10 and you install a COP file that has headset and accessories template version 1-12, then the chosen headset and accessories template version is 1-12. Headset and accessories template installed with the COP files is the preferred option. • If the Unified Communications Manager is currently installed with the headset and accessories template version 1-10 and you install a COP file that has headset and accessories template version 1-9, then the chosen headset and accessories template version is 1-9. Headset and accessories template installed with the COP files is the preferred option.
