 ### Creating a Callee
 For the callee, implement the callback to receive data and the methods to marshal and unmarshal data. When data needs to be received, use the **on** API to register a listener. When data does not need to be received, use the **off** API to deregister the listener.
 1. Configure the ability startup mode.
