title: Looking for a good SIP implementation in C#
body: <p>I saw a similar <a href="https://stackoverflow.com/questions/498056/c-sip-stack-library">question</a> from 1.5 years ago and I am hoping there is something better.</p>
  
  <p>I am looking for a totally managed C# implementation because I need it for the .NET Microframework, so I can't have .NET wrappers around C code. </p>
  
  <p>Has anyone run into a good C# implementation of the SIP protocol.  I should not that I don't care about codecs, mostly will be dealing with call control.</p>
