Modify dial-in access numbers by using Skype for Business Server Management Shell

To modify dial-in access numbers, use the Set-CsDialInConferencingAccessNumber cmdlet.

The following command modifies the DisplayName property for the dial-in conferencing access number with the Identity sip:RedmondDialIn@litwareinc.com. In this example, the display name is set to "Redmond Dial-In Access Number":

To do this, the Regions parameter is called, followed by the two regions (two string values separated by commas). Note that this command will fail unless both the Redmond and Seattle regions have already been defined in dial plans.

Set-CsDialInConferencingAccessNumber -Identity "sip:RedmondDialIn@litwareinc.com" -Regions "Redmond", "Seattle"
