NoAckReceivedEvent (OCSIP 3.1 RA Type)

```
public interface NoAckReceivedEvent
```
Event fired when a Dialog does not receive the expected ACK in time after sending a 2xx response to an INVITE or re-INVITE.
The Dialog automatically retransmits the 2xx response for 64*T1 seconds (32s). If no ACK is received in this time then, this event is fired. The dialog will be in the Confirmed state, but the application SHOULD terminate the dialog by sending a BYE.
