Well this came as surprise to me, snom have released the UC600 an Optimized for Microsoft ® Lync USB device.
To use the phone you will need Office Communicator 2007 R2 or later. I’m hopeful to get my hands on one of these to check the build quality meets the high standard on devices such as the snom 821.
