This paragraph should answer both of your questions:
You can think of “Force” as meaning “Start or resume recording now,” and “Never” as meaning “Stop recording now.” The “Don’t Care” options means, “Don’t change anything right now.”
You can also set ‘Settings’ → ‘Advanced Settings’ → Dialplan and Operational’ → ‘Call Recording Policy’ to either ‘Caller’ or ‘Callee’, depending on whose policy should be superior.
