Making "Lync Call" default

I just finished installing Lync server 2010 at work and noticed that the "click to call" feature on the client was not making a "lync call" the default for everyone. This is controlled in the CsClientPolicy for users. Here is the Powershell command to change it:

    Set-CsClientPolicy -EnableVOIPCallDefault $True
