You cannot send audio and video output when you accept a call or make a call in Communicator 2007 on a Terminal Server

On a Terminal Server, you accept a call or make a call in Microsoft Office Communicator 2007. When you do this, you cannot send audio and video output. However, you can receive audio and video output from the call.

This behavior occurs because output from local microphones and from local webcams is not sent to the Terminal Server.

This behavior is by design.
