You can deploy dial-in conferencing in the following topologies and configurations:

You can deploy Application service, Conference Attendant, and Conference Announcement in a central site, but not in a branch site.

If you deploy dial-in conferencing, you must deploy it in every pool where you deploy Lync Server 2010 Conferencing. You do not need to assign access numbers in every pool, but you must deploy the dial-in conferencing feature in every pool. This requirement supports the recorded name feature when a user calls an access number from one pool to join a Lync Server 2010 conference in a different pool.
