Dial-In Conferencing Scenario

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The following figure shows the relationships among the components that are required to support dial-in conferencing. The figure shows a single Front End Server and a single Mediation Server. In practice, there will probably be multiple load-balanced Front End Servers, each of which will be running all the shaded components, for each Enterprise Edition pool. There will also probably be multiple Mediation Servers.
