title: How to register SipSession.Listener in Android
body: <p>I'd like to be able to track SIP events using SipSession.Listener. For this purpose I would like to register the listener for incoming/outgoing sessions that any OTHER Android application might create. I'd like how I could register the listener for these events. I've searched the web but it seems there are not many samples for using the SipSession.Listener. 
  Thanks!</p>
