title: VOIP and background functionality
body: <p>I need to run my app continuously in background (not periodically), while supporting iOS 6.</p>
  
  <p>I ran <a href="http://www.raywenderlich.com/29948/backgrounding-for-ios" rel="nofollow">http://www.raywenderlich.com/29948/backgrounding-for-ios</a> example, which runs well for a while, but after some time (i guess 10 minutes limit or 100+ pings) it crashes.</p>
  
  <p>Following is the crash log</p>
  
  <pre><code>Application Specific Information:
  BKUnsuspendLimit TheBackgrounder[5183] exceeded 15 wakes in 300 sec
  </code></pre>
  
  <p>How can I avoid this crash?</p>
