Choosing the right end user devices for your OCS roll-out is important and not easy considering all the choices in the market.
If you are going through this process, the following Microsoft TechNet resource is a good start: http://technet.microsoft.com/en-us/office/ocs/bb970310.aspx. It lists all the webcam’s, headset’s, handset’s, speakerphones and desktop phones that have the Optimized for Microsoft Office Communicator designation, which basically means they have been tested and qualified by Microsoft as providing a high level of quality right from installation to feature usage (including a high quality audio/video experience).
I’ve had good personal experience with several of the Microsoft LifeCam webcam’s (VX-7000 and VX-5000). Although this site doesn’t list any Logitech devices, I’ve also had heard good experiences with the Logitech QuickCam webcam products.
