+
+``` java
+if (callEvent instanceof PlayCompleted) {
+     CallAutomationEventWithReasonCodeBase playCompleted= (CallAutomationEventWithReasonCodeBase) callEvent;
+     Reasoncode reasonCode = playCompleted.getReasonCode();

+     //Play audio completed, Take some action on completed event.
+     // Hang up call
+     callConnection.hangUp(true);
+}
+```
+
+### Example of how you can deserialize the *PlayFailed* event:
+
+``` java
+if (callEvent instanceof PlayFailed) {
+     CallAutomationEventWithReasonCodeBase playFailed = (CallAutomationEventWithReasonCodeBase) callEvent;
+     Reasoncode reasonCode = playFailed.getReasonCode();

 ```
