Configure the IP Address on a UM IP Gateway

  • Article

 

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

When you create a Unified Messaging (UM) IP gateway, you must define the IP address or the fully qualified domain name (FQDN) configured on the IP gateway or Session Initiation Protocol (SIP)-enabled IP Private Branch eXchange (PBX) that you're using. However, you can change the IP address after the UM IP gateway is created. The IP address configured on the UM IP gateway is the IP address configured on the network or LAN interface of the IP gateway or SIP-enabled IP PBX. If you create a UM IP gateway with an IP address and you view the properties of the UM IP gateway using the Get-UMIPgateway cmdlet, you can't use the IP address, you must use the name of the UM IP gateway. For example, Get-UMIPGateway MyUMIPGateway.

You can only configure a UM IP gateway with an IPv4 IP address. The IP Address field can accept an IPv6 address. However, IPv6 isn't supported.

Important

If you create a UM IP gateway using an FQDN, 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 the UM IP gateway's configuration information is updated correctly in the Active Directory directory service.

Prerequisites

Use the EMC to configure the IP address on 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. Select the UM IP gateway that you want to modify, and then in the action pane, click Properties.

  4. On the UM IP gateway Properties page, under IP Address, enter the IP address for the IP gateway or IP PBX.

    Note

    If you use an FQDN instead of an IP address on the UM IP gateway, verify that the correct DNS records have been created.

  5. Click OK to save your changes.

Use the Shell to configure the IP address on 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 configures a UM IP gateway named MyUMIPGateway with an IP address of 10.10.10.1.

Set-UMIPGateway -Identity MyUMIPGateway -Address 10.10.10.1

This example configures a UM IP gateway named MyUMIPGateway with an IP address of 10.10.10.10 and listens for SIP requests on TCP port 5061.

Set-UMIPGateway -Identity MyUMIPGateway -Address 10.10.10.10 -Port 5061
