   CCAPI_CALL_EV_CAPABILITY      -- From phone team: "...CCAPI_CALL_EV_CAPABILITY is generated for the capability changes but we decided to
                                    suppress it if it's due to state changes. We found it redundant as a state change implicitly implies a
                                    capability change. This event will still be generated if the capability changes without a state change.
