Create a UM Hunt Group

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

When you create a Unified Messaging (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 can't change any of the settings that you 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.

Prerequisites

• A UM dial plan has been created. For detailed steps, see Create a UM Dial Plan.

• A UM IP gateway has been created. For detailed steps, see Create a UM IP Gateway.

What Do You Want to Do?

• Use the EMC to create a UM hunt group

• Use the Shell to create a UM hunt group

Use the EMC to create a UM hunt group

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM hunt groups" entry in the Unified Messaging Permissions topic.

1. In the console tree, navigate to Organization Configuration > Unified Messaging.

2. In the work pane, click the UM IP Gateways tab.

3. In the result pane, select a UM IP gateway.

4. In the action pane, click New UM Hunt Group.

5. In the New UM Hunt Group wizard, view or complete the following fields:

   • 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.

   • 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's used only for display purposes in the EMC and the 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 of a UM hunt group name is 64 characters, and it can include spaces. However, it can't 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 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.

6. On the Completion page, confirm whether the UM hunt group was successfully created:

   • A status of Completed indicates that the wizard completed the task successfully.

   • A status of Failed indicates that the task wasn't completed. If the task fails, review the summary for an explanation, and then click Back to make any configuration changes.

7. Click Finish to complete the New UM Hunt Group wizard.

Use the Shell to create a UM hunt group

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM hunt groups" entry in the Unified Messaging Permissions topic.

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

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

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

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

For more information about syntax and parameters, see New-UMHuntGroup.
