The SDK takes care of starting and stopping the reactor, so in your app you shouldn't call reactor.run(), as it will be called by SIPApplication.start. Also note that SIP SIMPLE SDK runs the reactor in a separated thread, not the main thread, so you'll have to join it from the main thread or do something to prevent the program from exiting.
