Hello folks,
The new Communicator R2 has a feature to show the current configuration that the client is using. To retrieve your configuration settings, hold Ctrl key and right-click on the OCS 2007 Communicator icon located on systray area, and then click on Configuration Information.
The tip came from Office Communicatons Server Team, and the original post can be found here: http://communicationsserverteam.com/archive/2009/04/08/400.aspx
