Standalone A/V Conferencing Server

The option to deploy a standalone A/V conferencing server has been removed from Lync Server 2013. This role was geared toward supporting large A/V conferencing workloads, but the video conferencing codec change and performance improvements have negated the need to separate this role. The A/V conferencing role is now always installed on Front End servers within a pool, which helps to simplify deployments. Those migrating from older versions will notice the Front End servers taken on a much greater load.
