Use the New-UMHuntGroup cmdlet to create a Unified Messaging (UM) hunt group used to link incoming calls to a specific UM dial plan.

For information about the parameter sets in the Syntax section below, see Syntax.

New-UMHuntGroup -Name <String> -UMDialPlan <UMDialPlanIdParameter> -UMIPGateway <UMIPGatewayIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Organization <OrganizationIdParameter>] [-PilotIdentifier <String>] [-WhatIf [<SwitchParameter>]]

This example creates the UM hunt group MyUMHuntGroup that has a pilot identifier of 12345.

New-UMHuntGroup -Name MyUMHuntGroup -PilotIdentifier 12345 -UMDialPlan MyUMDialPlan -UMIPGateway MyUMIPGateway

This example creates the UM hunt group MyUMHuntGroup that has multiple pilot identifiers.

New-UMHuntGroup -Name MyUMHuntGroup -PilotIdentifier 5551234,55555 -UMDialPlan MyUMDialPlan -UMIPGateway MyUMIPGateway

The New-UMHuntGroup cmdlet creates a UM hunt group in Active Directory. Running this cmdlet enables all Mailbox servers associated with UM dial plans to communicate with an IP gateway. A UM hunt group must be created to allow communication between a UM IP gateway and a UM dial plan.

After this task is completed, a new UM hunt group is created.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "UM hunt groups" entry in the Unified Messaging permissions topic.


Parameter Required Type Description




The Name parameter specifies the UM hunt group name used for display purposes. This string can contain as many as 64 characters, and it must be unique.




The UMDialPlan parameter specifies the UM dial plan used with the UM hunt group.




The UMIPGateway parameter specifies the UM IP gateway to be associated with the UM hunt group.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




This parameter is available only in on-premises Exchange 2013.

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The Organization parameter is reserved for internal Microsoft use.




The PilotIdentifier parameter specifies the number string used to uniquely identify the pilot access number for the specified IP gateway. This number must match the subscriber access number configured in the UM dial plan.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
