Routing

In prior versions of Communications Server, each Mediation Server could only be associated with a single gateway, PBX, or SIP trunk. A new feature in Lync Server is the capability for a single Mediation Server to be associated with multiple gateways. This allows for a single Mediation Server to connect to multiple media gateways or IP PBXs, which can significantly reduce the amount of server hardware required to implement a redundant solution. An example of a Mediation Server connecting to two IP PBXs and a media gateway is shown in Figure 17.17.
