title: Free SMS Gateway Engine
body: <p>Recently I was looking for SMS (mainly) gateway, free, and preferably, open source. I ran into <a href="http://www.kannel.org" rel="noreferrer">Kannel</a> which fits my needs so far, and more. However, I was hoping for something that is Windows-based (Kannel is Linux-based)... well, I know Kannel can be compiled and run using Cygwin, but it won't be as reliable as on Linux.</p>
  
  <p>Does anyone know about similar thing on Windows? I'm not looking for a full-featured enterprise solution, something as simple as Kannel (and engine with few API's) is okay with me.</p>
