You must define trunks in your Enterprise Voice deployment. For Location-Based Routing, you must create a trunk configuration per trunk. Use the Lync Server Topology Builder to define your trunks, and use the Lync Server Windows PowerShell command, New-CsTrunkConfiguration, or the Lync Server Control Panel to define the corresponding trunk configurations. More information on how to enable Location-Based Routing on trunk configurations can be found in the section, Enable Location-Based Routing to Trunks, in the topic, Enabling Location-Based Routing. For this example, the following table illustrates the trunks used in this scenario.

For more information, see Define additional Trunks in Topology Builder.

You must define voice policies for your Enterprise Voice deployment. Define a Voice Policy to enforce Location-Based Routing restrictions to a subset of users if only a subset of them is required to use Location-Based Routing. For this example, the following table illustrates the voice policies used in this scenario. Only settings that are specific to Location-Based Routing are included in the table for illustration purposes.
