Android :: How To Stop / Hang Up Outgoing Call?

I'm just doing an application that controls who to call and how many rings let the call do. For example, to not wake up someone in the morning we only do 3 tones. I'm using the standard BroadcastReceiver method to stop the call from going out. I explain here for the people who want to do it, also.

[ Manifiest ] 1.- You need enough permissions: <uses-permission
android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.CALL_PHONE" />
To make calls and process outgoing calls.

2.- You need a broadcast receiver that catches the broadcast intent:
<receiver android:name=".receiver.PhoneOutgoingCallReceiver" android:enabled="true" >
<intent-filter android:priority="0">
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter> </receiver>
[Code]

3.- You controls who can call in the:
@Override public void onReceive(Context context, Intent intent) { }
