Mr. Culp,
The quickest way is to see what commands for the CLI configuration can by achieved by doing the following.
In CCA go to system > Preferences > Advanced tab and enable CLI postview of IOS voice features. (If not already enabled)
Configure a multi-site via CCA and you will will see a pop window with all the CLI commands that are sent to the UC500 for the multi-site configuration. Specific to the configuration you are trying to achieve.
Thank you,
