The Location-Based Routing Conferencing application is disabled by default. Before enabling this application, you need to determine the right priority to assign for the application. To determine this priority, run the following cmdlet in Lync Server Management Shell:

Get-CsServerApplication -Identity Service:Registrar:<Pool FQDN>

In this cmdlet, <Pool FQDN> is the pool in which the Location-Based Routing Conferencing application is to be enabled.

This cmdlet will return the list of the applications hosted by Lync Server and the priority value for each of them. The Location-Based Routing Conferencing application needs to be assigned a priority value larger than the “UdcAgent” application and smaller than the “DefaultRouting”, “ExumRouting” and “OutboundRouting” applications. We recommend that you assign the Location-Based Routing Conferencing application a priority value that is one point higher than the priority value of the “UdcAgent” application.

For example, if the “UdcAgent” application has a priority value of “2”, the “DefaultRouting” application has a priority value of “8”, the “ExumRouting” application has a priority value of “9” and the “OutboundRouting” application has a priority value of “10” then you should assign the Location-Based Routing Conferencing application a priority value of “3”. Doing so would place the priority of the applications in the following order: Other applications (Priorities: 0 to 1), “UdcAgent” (Priority: 2), Location-Based Routing Conferencing application (Priority: 3), other applications (Priorities: 4 to 8), “DefaultRouting” (Priority: 9), “ExumRouting” (Priority: 10) and “OutboundRouting” (Priority: 11).

After you find the correct priority value for the Location-Based Routing Conferencing application, type the following cmdlet for each Front-End pool or Standard Edition Server that homes users enabled for Location-Based Routing:

New-CsServerApplication -Identity Service:Registrar:<Pool FQDN>/LBRouting -Priority <Application Priority> -Enabled $true -Critical $true -Uri http://www.microsoft.com/LCS/LBRouting

For example:

New-CsServerApplication -Identity Service:Registrar:LS2013CU2LBRPool.contoso.com/LBRouting -Priority 3 -Enabled $true -Critical $true -Uri http://www.microsoft.com/LCS/LBRouting

After using this cmdlet, restart all Front End servers in the pool or the Standard Edition Servers where the Location-Based Routing Conferencing application has been enabled.

Once the Location-Based Routing Conferencing application has been successfully enabled and all applicable Lync servers have been restarted, all conferences organized by Lync users enabled for Location-Based Routing will be monitored to prevent PSTN toll bypass
