ML = Optimised for Microsoft Lync Normal = Optimised for leading UC softphone brands This is basically "just" a certification. Devices that have been optimised for Lync go through rigorous audio quality tests to ensure you get good audio quality. Non-optimised devices may have lower audio quality because, for example, inferior audio components were used.
