DialogTimeoutEvent (JAIN SIP 1.2 RA Type)

```
public interface DialogTimeoutEvent
```
This event is fired on a dialog activity when the RA Entity determines that the dialog has expired. This expiry behaviour is implementation-specific.
It is recommended that RA implementations use RFC4028 (SIP Session Timers) to reliably determine when a dialog is no longer in use.
