The Mediation Server role in Lync Server 2010 is responsible for providing voice features to end users that allow them to connect with the Public Switched Telephone Network (PSTN) or another PBX. The Mediation Server provides a number of benefits to a Lync Server 2010 deployment that are discussed in greater detail throughout this section.
Perhaps one of the biggest improvements in Lync is the fact that the Mediation Server can now be collocated with a Front End Server, reducing the number of servers required in a deployment. This chapter focuses on configuration of each voice component.
