Unified Communications How-To
This package can help you out to explain some of the Office Communicator, Communications Server Attendant, Live Meeting through a desktop or web application. It is really helpful if you want to improve your end-user knowledge of OCS using self-training. You can also customize the tool to display only the features that you have deployed in your environment.
The Microsoft Unified Communications "How-To" training tool is a Microsoft Silverlight™ 2 application that provides step-by-step instructions for common UC tasks. You can customize the How-To application to your company's needs based on the UC features you've installed. For example, if you have installed all UC features except Communicator Mobile and Communicator Group Chat, you can modify the XML file so that those features and topics do not appear in the interface.
