title: Windows Mobile - Stop Main Phone App
body: <p>Is there a way to make Windows Mobile not use the main phone app?  I have my own phone app that I want to handle phone transactions for a business device.  </p>
  
  <p>My app works fine (detects the call and can hang up), but the main phone app still wants to allow the user to answer a call normally.  I can try to hide the incoming call window or programmatically press the ignore key, but that is a bit clunky.</p>
  
  <p>Basically, I need a way to make the built in phone app not know about incoming calls.</p>
  
  <p>Any advice would be appreciated!</p>
  
  <p>In case it matters I am using a Symbol MC70 running Windows Mobile 5.</p>
  
  <p>Thanks!</p>
  
  <p>EDIT: Thanks to djhowell's answer to <a href="https://superuser.com/questions/30798/windows-mobile-5-stop-toast-popup-for-incomming-calls">this question</a> I now know that the offending app is cprog.exe.  But apparently it is hard to kill because <a href="http://social.msdn.microsoft.com/Forums/en-US/windowsmobiledev/thread/82eef36d-7512-480a-96d6-0ba43d57556b" rel="nofollow noreferrer">services.exe keeps bringing it back</a>.</p>
