Select each feature that you want to enable for the Front End pool. At a minimum, you must deploy instant messaging (IM), which is always enabled and cannot be deselected. You also have the option of deploying other features, such as conferencing, Enterprise Voice, and call admission control (CAC). Some features are dependent on your topology.

If you would like to enable CAC in your deployment, you must enable CAC in exactly one pool per central site. We recommend CAC if you are deploying voice features or A/V Conferencing.

For details about specifying features for an Enterprise Edition pool, see Define and Configure a Front End Pool or Standard Edition Server in the Deployment documentation.
