Unified Messaging hunt group
Additionally, the dial plan will need to be associated with one or more UM servers. The UM hunt group itself is created for a specific UM IP gateway object. It is also possible to create more than one UM hunt group per UM IP gateway. These objects work together in the following order:
- The IP gateway initiates a session with the UM server by using SIP.
- The SIP header includes the pilot number.
- The UM server verifies that the number in the SIP header is part of a particular hunt group.
- The associated UM server accepts the call.
Two parameters in a UM hunt group can be configured: the UM dial plan and the pilot identifier or pilot number. You will add the UM hunt group to the UM IP gateway that you previously created and then specify the UM dial plan you want to link to. Finally, specifying a pilot number and creating the new UM hunt group allows the UM server to begin accepting inbound calls.
Creating a new UM hunt group
Use the following steps to create a new UM hunt group:
- Open the EMC with an administrator account that has the Exchange Organization Administrator role.
- Expand "Organization Configuration" and click "Unified Messaging."
- Select the "UM IP Gateways" tab.
- Select an existing UM IP gateway.
- Select "New UM Hunt Group" in the "Actions" pane.
- Type the name of the hunt group in the "Name" field, as shown below.
- Click "Browse," select the UM dial plan you want to link to, and then click "OK."
- Type the number of the pilot identifier for the hunt group and then click "New." (Be sure to enter in the correct pilot number because you cannot change this number without removing and then re-creating the hunt group.)
- Click "Finish."
As an alternative to the EMC, you can also use the New-UMHuntGroup cmdlet in the EMS, like in this example:
[PS]C:>New-UMHuntGroup -Name "ROC-HG" -PilotIdentifier 12700 -UMDialplan "Rochester NY" -UMIPGateway "AudioCodes - Mediant 2000"
