If there is another audio device connected to the computer and interacting with Microsoft Office Communicator, the device with a higher priority is selected by Microsoft Office Communicator. Additionally, if you have manually selected another speaker device, the phone does not override this choice. Use the Set Up Audio and Video page of Microsoft Office Communicator to test the interaction of the device with Microsoft Office Communicator. Note If you change the default device while Microsoft Office Communicator is running, you have to restart Microsoft Office Communicator for the change to be implemented.
