SipRegistrationListener callbacks are not getting fired
<p>I am trying to run the SIPDemo downloaded from Google Andoid sample applications, but not able to get it running.</p>

<p>The issue I am facing is that after I invoke SipManager.open passing it a profile and a pending intent, it should start the registration process with the SIP Provider, in my case I am using an already registered account to connect. But none of the callbacks in SipRegistrationListener are getting fired. Not sure weather the application is able to register or not, weather the app is able to even hit the SIP server or not.</p>

<p>Also please note that I am passing null as listner in SipManager.open call but in next line providing the listener by invoking SipManager.setRegistrationListener.</p>

<p>Below is the complete code of the FullScreenActivity that I've modified a bit after downloading.</p>
