title: UCC API for Lync
body: <p>I need software that will allow me to change the call forwarding in Lync's voip. No such software (other than Microsoft's own client) exists, so I need to write it myself. I have Visual Studio 2010, but it's unclear just which SDKs need to be installed... I seem to be in some dependency hell where when I reach the end of it all it's looking for "VS 2010 Express Edition" and I can't install. </p>
  
  <p>Where do I need to start?</p>
  
  <p>Also, I've been poking around in UccApi.dll a bit. Is there a single function there that sets up call forwarding? Would it be possible to just rundll32 this with a few parameters and sidestep the need to kludge together a crappy console app?</p>
