title: Which SIP server to deploy for my Android VoIP app?
body: <p>I am building an android application that supports VoIP/IM/Presence with the available Android SIP stack. I also need to deploy a SIP server to enable the mentioned SIP functionalities as part of my project.</p>
  
  <p>Developing the Android app seems easy with all the available resources and abundant source codes online. However, I am seriously stuck with deploying a SIP server to communicate with the app.</p>
  
  <p>I experimented for around a month with OpenSIPS but it seemed a bit advanced to my level. Especially that it is runs on a linux environment.</p>
  
  <ol>
  <li><p>Any suggestions for other easy-to-deploy and easy-to-deal-with SIP servers?</p></li>
  <li><p>I haven't done extensive research on this yet, but what do you think of Microsoft Lync Server for that purpose?</p></li>
