get duration fails at first time.

Hi,plugin was wrong at the first time we start the "startPhoneCall".
I couldn't get duration at the first time.
It always shows "completed" immediately, then duration was not correct.
I found this code :
"
switch (event.type) {
case RawEventType.inbound:
// Nothing
break;
case RawEventType.outbound:
_changeStatus(matching, PhoneCallStatus.connecting);
break;
case RawEventType.connected:
_changeStatus(matching, PhoneCallStatus.connected);
break;
case RawEventType.disconnected:

      /// We ended the call--- makes sure it's not some ridiculously long call
    _changeStatus(matching, PhoneCallStatus.disconnected);

      break;
  }

"
The first time we start the call, status is "disconnected" and that the problem.
