My OCS / Exchange UM lab is now live at labcenter.se
We review and build OCS 2007 R2 from scratch with all its various roles including Exchange 2010 UM. The lab contains many practical exercises to bring up the basic functions such as IM, online meetings in Live Meeting, Federation and Desktop Sharing. After the basic functions we will also immerse ourselves in the Enterprise Voice, SIP trunks, SIP gateways and Exchange UM-role
So if you are waiting for the next step in your UC deployment or are in the planning stage or process of rolling out Microsoft Unified Communications in your organization i highly recommend you to get some practical skills first by attending this lab.
