Make “Lync Call” default

After implementation of Enterprise Voice in Lync 2010, we noticed that the Work number became the default calling method from Lync.

We wanted to change this behavior, and make Lync Call the default and preferred calling method.

To solve this, the following PowerShell command was issued:
Set-CsClientPolicy -EnableVOIPCallDefault $True
