SessionExpiredEvent (OCSIP 3.1 RA Type)

```
public interface SessionExpiredEvent
```
This event notifies the app that the session timer has expired for a dialog, so the app should terminate the dialog by sending BYE. The RA won't automatically send BYE, it is up to the application to decide how to handle session expiration. However the RA will send a BYE if this event is not processed by any SBBs. This is to ensure that dialogs from deactivated services get cleaned up.
