title: How to retrieve missed calls on Android SDK 2.2
body: <p>in my app I should do some action when a call comes but not answered by the user. </p>
  
  <p>I have searched in the <em>android.telephony</em> and the <em>NotificationManager</em>, but I haven't found a method to solve this problem.</p>
