Create a UM IP Gateway

 

Applies to: Exchange Server 2013, Exchange Online

Topic Last Modified: 2013-04-16

When you create a Unified Messaging (UM) IP gateway, you enable Exchange servers to connect to a new Voice over IP (VoIP) gateway, a Private Branch eXchange (PBX) enabled for Session Initiation Protocol (SIP), an IP PBX, or a session border controller (SBC). 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.

For additional management tasks related to UM IP gateways, see UM IP Gateway Procedures.

  • Estimated time to complete: 3 minutes.
  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "UM IP gateways" entry in the Unified Messaging Permissions topic.
  • Before you perform these procedures, confirm that a UM dial plan has been created. For detailed steps, see Create a UM Dial Plan.
  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard Shortcuts in the Exchange Admin Center.

  1. In the EAC, navigate to Unified Messaging > UM IP gateways, and then click New Add Icon.
  2. On the New UM IP gateway page, enter the following information:
    • Name   Use this box to specify a unique name for the UM IP gateway. This is a display name that appears in the EAC. 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 name that you want. The UM IP gateway name is required, but it's used for display purposes only. 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. However, it can't include any of the following characters: " / \ [ ] : ; | = , + * ? < >.
    • Address   You can configure a UM IP gateway with either an IP address or a fully qualified domain name (FQDN). Use this box to specify the IP address configured on the VoIP gateway, SIP-enabled PBX, IP PBX, or SBC, or an FQDN. This box accepts only FQDNs that are valid and formatted correctly.
      You can enter alphabetical and numeric characters in this box. IPv4 addresses, IPv6 addresses, and FQDNs are supported. 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 VoIP 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’ve correctly configured a DNS host record for the VoIP 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.
    • UM dial plan   Click Browse 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.
  3. Click Save.

This example creates a UM IP gateway named MyUMIPGateway that enables Exchange servers to start accepting calls from a VoIP gateway, a PBX enabled for SIP, an IP PBX, or an SBC that has an IP address of 10.10.10.1.

New-UMIPGateway -Name MyUMIPGateway -Address 10.10.10.1

This example creates a UM IP gateway named MyUMIPGateway that enables Exchange servers to start accepting calls from a VoIP gateway, a PBX enabled for SIP, an IP PBX, or an SBC that has an FQDN of MyUMIPGateway.contoso.com and listens on port 5061.

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

This example creates a UM IP gateway named MyUMIPGateway and prevents the UM IP gateway from accepting incoming calls or sending outgoing calls, sets an IPv6 address, and allows the UM IP gateway to use IPv4 and IPV6 addresses.

New-UMIPGateway -Identity MyUMIPGateway -Address fe80::39bd:88f7:6969:d223%11 -IPAddressFamily Any -Status Disabled -OutcallsAllowed $false
