How to know callee is answered the call (What is the phone state when he lift the call)

Question

I am trying to know how to alert when the callee lifts the call. I have used PhoneStateListener along with BroadcastReceiver.

Generally it has three states CALL_STATE_IDLE , CALL_STATE_OFFHOOK, CALL_STATE_RINGING.

CALL_STATE_OFFHOOK state was calling when call is connecting, No state of the above three states was called after callee answered call.

Here is my BroadcastReceiver.

public class PhoneStateBroadcastReceiver extends BroadcastReceiver
{

   @Override
    public void onReceive(Context context, Intent intent)
    {

        TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        telephonyManager.listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE);

    }

    public class CustomPhoneStateListener  extends PhoneStateListener
    {

        Context context; //Context to make Toast if required 
        ActivityManager activityManager;

        public CustomPhoneStateListener(Context context)
        {
            super();
            this.context = context;
        }

        @Override
        public void onCallStateChanged(int state, String incomingNumber) 
        {
            super.onCallStateChanged(state, incomingNumber);
            Log.v("PhoneStateBroadcastReceiver", "onCallStateChanged state"+state);


            switch (state) 
            {
            case TelephonyManager.CALL_STATE_IDLE:
               Toast.makeText(context, "=CALL_STATE_IDLE==", Toast.LENGTH_LONG).show();
             break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Toast.makeText(context, "CALL_STATE_OFFHOOK", Toast.LENGTH_LONG).show();

                break;
            case TelephonyManager.CALL_STATE_RINGING:
                Toast.makeText(context, "CALL_STATE_RINGING", Toast.LENGTH_LONG).show();

                break;
            default:
                break;
            }
        }
      }
 }

I have seen some applications there are recording a voice when call was accepted. I want to know the state of accepting call.

Is there any other state or listener to know when the callee is answered the call?

The state will be OFF_HOOK

Device call state: Off-hook. At least one call exists that is dialing, active, or on hold, and no calls are ringing or waiting.

You can see on this link:
