C# :: Delegates / Events Are Just Not Sticking

In my week long quest to understand delegates/events, all the contrived examples have made my understanding worse. I've been trying to make this simple console project work, where you have a Person, Phone and Switchboard class. My thinking was, that the Phone object would broadcast to any SwitchBoard that's listening, the SwitchBoard would broadcast to the proper phone on the other end and the phone would do the same for any person that's listening.

This is what I have so far, and after adding the SwitchBoard.

class Phone {
public delegate void IncomingCallHandler();
public event IncomingCallHandler IncomingCallEvent;

public delegate void OutGoingCallHandler(Phone p);
public event OutGoingCallHandler OutGoingCallEvent;
