Have you tried to install the software and if you did what were the error messages if any? In many cases an application (not necessarily this one) will work but the company wishes to avoid the problems of supporting it in a server environment. If you install the software you will get no support if there is a problem.
I was finally able to install MagicJack on Win 2008. The two things I did were to turn off the Enhanced Security Configuration (Server Manager / Configure IE ESC) and to start up the Windows Audio service. I have no idea if the IE ESC was even necessary but I wanted it off anyways and kind of made sense. I have not yet set MagicJack up as a service but I'll be doing that tomorrow.
