You have a Lync Server 2013 infrastructure. The infrastructure contains two sites and is configured for Enterprise Voice. The sites are located in Chicago and Toronto. Each site has a distinct voice policy, PSTN usage, voice route, and trunk translation rule as shown in the following table. The voice policy of each site contains the PSTN usage record of its respective site. The voice route of each site uses the trunk assigned to its respective site. The voice route of each site is assigned to the PSTN usage of its respective site. You need to ensure that all outbound voice calls to the PSTN from the users in the Toronto site are routed through the trunk at the Toronto site. Calls must use the Mediation Server at the Chicago site if the Mediation Server at the Toronto site is unavailable. What should you do?
