A Unified Messaging (UM) hunt group is a logical representation of a 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 UM dial plan.

Note:
If you associate a UM dial plan with the UM IP gateway when you create a UM IP gateway, a UM hunt group will also be created.

For additional tasks related to UM hunt groups, see UM Hunt Group Procedures.

Warning:
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.

What do you want to do?

Use the EAC to create a UM hunt group

  1. In the EAC, navigate to Unified Messaging > UM dial plans. In the list view, select the UM dial plan you want to change and then click Edit Add Icon.

  2. On the UM Dial Plan page, under UM Hunt Groups, on the toolbar, click Add Add Icon.

  3. On the New UM Hunt Group page, complete the following boxes:

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

    • Name   Use this 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 EAC 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 Browse 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 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 Initiation Protocol (SIP) Uniform Resource Identifier (URI) can be used in this box. Alphanumeric characters are accepted in this box. For legacy PBXs, a numeric value is used as a pilot identifier. However, some IP PBXs can use SIP URIs.

  4. Click Save.

Use the Shell to create a UM hunt group

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

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

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

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