Downloading RD user cal from Microsoft Volume site

Hello,

I am running across Microsoft Volume site for past 30 mins, but cannot find anything like RD User CAL license.

only thing closet I can see is "WinRemote Desktop SrvsCAL 4.5 w/Application Virt for Term" , is that the same?

I have build a traditional Win 2008R2 terminal server (session host) and no remote app.

What exactly the RD user cal name should look like?

Thanks in Advance
