It takes several steps to modify a voice route within a routing configuration. In this example, we start by retrieving the routing configuration object by calling the Get-CsRoutingConfiguration cmdlet. We assign the object retrieved (there will be only one) to the variable $a.

In line 2 of this example we retrieve the contents of the Route property from variable $a, which is a collection of voice route objects. We then pipe that collection to the Where-Object cmdlet, where we search the collection for all voice route objects with a Name matching the string LocalRoute. We assign that object to the variable $b.

Next, we modify the LocalRoute voice route object by assigning the value $False to the property SuppressCallerId. By updating that object we’ve updated the object in variable $a. However, that object is still only in memory. As a final step, we need to save those changes by passing $a to the Instance parameter of the Set-CsRoutingConfiguration cmdlet.

This is not the recommended way of modifying a routing configuration. To modify a routing configuration, simply change the individual voice routes with the Set-CsVoiceRoute cmdlet, as shown here:

Set-CsVoiceRoute -Identity LocalRoute -SuppressCallerId $False

That one line will accomplish the same task shown in Example 1.

$a = Get-CsRoutingConfiguration $b = $a.Route | Where-Object {$_.Name -match "LocalRoute"} $b.SuppressCallerId = $False Set-CsRoutingConfiguration -Instance $a
