Optional Dedicated A/V Conferencing Role

In scenarios that require heavy conferencing resources, or MCUs, the A/V Conferencing role can be split off from the Front End Server role. Multiple A/V servers can be placed in a pool and this A/V pool can be designated as the conferencing resource for many other pools. This topology offers a distinct advantage enabling conference-centric enterprises the capability to provide a highly available conferencing resource to the users, but also keeping this resource-intensive application isolated from the day-to-day IM presence and telephony services. Additionally, this enables an enterprise to virtualize basic telephony services while providing physical hardware for A/V services.
