title: ios making call programmatically without quitting app
body: <p>Is there any way to make a call programmatically without exiting from current app? 
  I did a research, but all answers are with:</p>
  
  <pre><code>[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
  </code></pre>
  
  <p>This is not what I want, I need also to access the voice stream.</p>
