+/**
+* Base class for MCE refers, inherited by both CMceInRefer and CMceOutRefer.
+*
+* CMceRefer represents peer-to-peer connection made with remote terminal.
+* This connection is also known as dialog and it is set up using SIP REFER
+* method.
+*
+* MCE refers are typically used for asking remote terminal to perform
+* some action. One such action is session transfer.
+*
+* The refer is finally terminated by the endpoint performing the action.
+* Refer can implicitically also create an event which is used to inform
+* how the action proceeds. In such case refer and event and tied together
+* and are finally terminated simultaneously.
+*
+* If for any reason instance of this class is deleted while in active state,
+* event is automatically terminated by MCE server.
