When a video call is attempted on using Office Communicator 2007 R2 ver 3.5.6907.37 an error message is received "Call was not completed or has ended" and a busy signal is sounded until the error window is closed. It seems as though there is no webcam connected to the computer, however the webcam does work with the software provided by the manufacturer.
We have tried this with the Logitech Quickcam E250 and the Microsoft Lifecam NX-6000
The user is able to have a Conversation (chat) but is not able to make video call.
Thanks for the assistance...
