Use the New UM Hunt Group Wizard to create a new Unified Messaging (UM) hunt group. When you create a UM hunt group, a UM hunt group object is created in the Active Directory directory service and is a logical representation of an existing Private Branch eXchange (PBX) or IP PBX hunt group. A UM hunt group acts as a connection or link between a UM IP gateway and a dial plan. After you create a UM hunt group, you cannot change any of the settings that you have defined. If you want to change the UM hunt group settings, you must delete the hunt group and then create another hunt group that has the appropriate settings.

Associated UM IP gateway
  • This display-only field shows the name of the UM IP gateway that will be associated with the UM hunt group.

Hunt group name
  • Use this text box to create the display name for the UM hunt group.

  • A UM hunt group name is required and must be unique, but it is used only for display purposes in the Exchange Management Console and the Exchange Management Shell. If you have to change the display name of the hunt group after it has been created, you must first delete the existing hunt group and then create another hunt group that has the appropriate name.

  • If your organization uses multiple hunt groups, we recommend that you use meaningful names for your hunt groups. The maximum length that a UM hunt group name can be is 64 characters, and it can include spaces. However, it cannot include any of the following characters: " / \ [ ] : ; | = , + * ? < >..

Dial plan
  • Click the Browse button to select the dial plan that will be associated with the UM hunt group. Associating a hunt group with a dial plan is required.

  • A UM hunt group can be associated with only one UM IP gateway and one UM dial plan.

Pilot identifier
  • Use this text box to specify a string that uniquely identifies the pilot identifier or pilot ID that is configured on the PBX or IP PBX.

  • An extension number or a Session Initiated Protocol (SIP) Uniform Resource Identifier (URI) can be used in this field. Alphanumeric characters are accepted in this field. For legacy PBXs, a numeric value is used as a pilot identifier. However, some IP PBXs can use SIP URIs.
