A Unified Messaging (UM) IP gateway establishes a logical link between the IP gateway device, a UM IP gateway, and single or multiple UM hunt groups. When you create a new UM IP gateway, you enable Unified Messaging servers to connect to a new IP gateway or an IP Private Branch eXchange (PBX) enabled for Session Initiation Protocol (SIP). Immediately after you create a UM IP gateway, you should create a new UM hunt group and then associate the UM hunt group with the UM IP gateway. You can associate the UM IP gateway with one or more UM dial plans by creating one or more UM hunt groups.

Prerequisites

What Do You Want to Do?

Use the EMC to create a UM IP gateway

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM IP gateways" 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 action pane, click New UM IP Gateway.

  4. In the New UM IP Gateway wizard, complete the following fields:

    • Name   Use this text box to specify a unique name for the UM IP gateway. This is a display name that appears in the EMC. If you have to change the display name of the UM IP gateway after it's been created, you must first delete the existing UM IP gateway, and then create another UM IP gateway that has the appropriate name. The UM IP gateway name is required, but it's used for display purposes only. When you’re using the Get-UMIPGateway cmdlet, you can’t enter the IP address that’s configured on the UM IP gateway. You must use the name of the UM IP gateway. The name that’s specified on the Identity parameter with the Get-UMIPGateway cmdlet can be the same as or different from the host name of the UM IP gateway. For example, Get-UMIPGateway MyUMIPGateway.

      Because your organization may use multiple UM IP gateways, we recommend that you use meaningful names for your UM IP gateways. The maximum length of a UM IP gateway name is 64 characters, and it can include spaces.

    • IP address   You can configure a UM IP gateway with either an IP address or an FQDN. Use this field to specify the IP address configured on the IP gateway or SIP-enabled IP PBX.

      Although you can enter alphabetical and numeric characters in this text box, IPv4 addresses that are correctly formatted are required. IPv6 addresses aren't supported even though they can be entered into this field.

    • Fully qualified domain name (FQDN)   You can configure a UM IP gateway with either an IP address or an FQDN. Use this text box to enter the FQDN for the UM IP gateway or SIP-enabled IP PBX. This text box accepts only FQDNs that are valid and formatted correctly.

      If you want to use mutual Transport Layer Security (mutual TLS) between a UM IP gateway and a dial plan operating in either SIP secured or Secured mode, you must configure the UM IP gateway with an FQDN. You must also configure it to listen on port 5061 and verify that any IP gateways or IP PBXs have also been configured to listen for mutual TLS requests on port 5061. To configure a UM IP gateway, run the following command: Set-UMIPGateway -identity MyUMIPGateway -Port 5061.

      If you use an FQDN, you must also make sure that you have correctly configured a DNS host record for the IP gateway so that the host name will be correctly resolved to an IP address. Also if you use an FQDN instead of an IP address, and the DNS configuration for the UM IP gateway is changed, you must disable and then enable the UM IP gateway to make sure that configuration information for the UM IP gateway is updated correctly in Active Directory.

    • Dial plan   Click the Browse button to select the UM dial plan that you want to associate with the UM IP gateway. When you select a UM dial plan to associate with a UM IP gateway, a default UM hunt group is also created and associated with the UM dial plan that you selected. If you don't select a UM dial plan, you must manually create a UM hunt group and then associate that UM hunt group with the UM IP gateway that you create.

  5. On the Completion page, confirm whether the UM IP gateway 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.

  6. Click Finish to complete the New UM IP Gateway wizard.

Use the Shell to create a UM IP gateway

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

This example creates a UM IP gateway named MyUMIPGateway that enables a Unified Messaging server to start accepting calls from an IP gateway that has an IP address of 10.10.10.1.

Copy Code
New-UMIPGateway -Name MyUMIPGateway -Address 10.10.10.1

This example creates a UM IP gateway named MyUMIPGateway that enables a Unified Messaging server to start accepting calls from an IP gateway that has an FQDN of MyUMIPGateway.contoso.com and listens on port 5061.

Copy Code
New-UMIPGateway -Name MyUMIPGateway -Address "MyUMIPGateway.contoso.com" -Port 5061
