title: Difference between Android SipAudioCall and Android Telecom Call
body: <p>I want to create an Android application which uses the SIP protocol.</p>
  
  <p>I found the docs for the SIP implementation in Android:</p>
  
  <p><a href="http://developer.android.com/guide/topics/connectivity/sip.html" rel="nofollow">http://developer.android.com/guide/topics/connectivity/sip.html</a></p>
  
  <p>My question is what exactly is the difference between this package and <code>Telecom</code> package which also got a <code>Call</code> object? When do I use one and when should I use the other?</p>
