If my company purchases Windows Server 2008 r2 CALs in India could we then use them on US Versions of Windows Server 2008 r2?

Hi, For licensing related issue, you’d better contact Microsoft licensing team. In the United States and Canada, you may call the licensing team directly at 1-800-426-9400 (select option 4), Monday through Friday, 6:00 A.M. to 5:30 P.M. (PST) to speak directly to a Microsoft licensing specialist. In this way, you will know the detailed information about license. Worldwide customers can use the Guide to Worldwide Microsoft Licensing Sites http://www.microsoft.com/licensing/worldwide.aspx to find contact information in their locations.
