After you create a Unified Messaging (UM) IP gateway, you can view or configure a variety of settings. For example, you can configure the IP address or a fully qualified domain name (FQDN), configure outgoing call settings, and enable or disable the Message Waiting Indicator. 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.

Prerequisites

A UM dial plan has been created. For detailed steps, see Create a UM Dial Plan.

What Do You Want to Do?

Use the EMC to view or configure UM IP gateway properties

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, and then select the UM IP gateway that you want to configure.

  3. In the action pane, click Properties.

  4. Use the General tab to view and configure settings for the UM IP gateway. For example, you can configure the IP address that points to an IP gateway or Private Branch eXchange (PBX) enabled for Session Initiation Protocol (SIP) on your network. You can also change the display name of the UM IP gateway that was configured when the UM IP gateway was created. You can view or configure the following settings:

    • Status   This display-only field shows the status of the UM IP gateway.

    • Modified   This display-only field shows the date that the UM IP gateway was last modified.

    • 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.

    • Allow outgoing calls through this UM IP gateway   Select this check box to allow the UM IP gateway to accept and process outgoing calls. This setting doesn't affect call transfers or incoming calls from an IP gateway.

      By default, when the UM IP gateway is created, this setting is enabled. If you disable this setting, users associated with the dial plan won't be able to make outgoing calls through the IP gateway defined in the Address field.

    • Allow Message Waiting Indicator   Select this check box to allow voice mail notifications to be sent to users for calls taken by the UM IP gateway. This setting allows the UM IP gateway to receive and send SIP NOTIFY messages for users. The default setting is enabled by default and allows for message waiting notifications to be sent to users.

      Message Waiting Indicator is a feature found in most legacy voice mail systems. In its most common form, it lights a lamp on the voice mail subscriber's phone to indicate the presence of a new voice message.

      Message Waiting Indicator can refer to any mechanism that indicates the existence of a new message. The voice mail message could be a new or unheard voice message. The indication that a new voice message has arrived can be found in the Inbox in clients such as Outlook and Outlook Web App. It can take the form of a Short Messaging Service (SMS) or text message sent to a registered mobile phone, an outbound call made from an Exchange Unified Messaging server to a preconfigured number to play the new item, or a lighted desktop phone lamp for a user.

Use the Shell to configure UM IP gateway properties

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 modifies the IP address of a UM IP gateway named MyUMIPGateway.

Copy Code
Set-UMIPGateway -Identity MyUMIPGateway -Address 10.10.10.1

This example prevents the UM IP gateway from accepting incoming calls and prevents outgoing calls.

Copy Code
Set-UMIPGateway -Identity MyUMIPGateway -Address 10.10.10.1 -Status 2 -OutcallsAllowed $false

This example enables the UM IP gateway to function as an IP gateway simulator and can be used with the Test-UMConnectivity cmdlet.

Copy Code
Set-UMIPGateway -Identity MyUMIPGateway -Simulator $true
Important:
There is a period of latency before all changes that you make to the configuration of a UM IP gateway replicate to all Unified Messaging servers in the same UM dial plan as the UM IP gateway.

For more information about syntax and parameters, see Set-UMIPGateway.

Use the Shell to view UM IP gateway properties

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 displays a formatted list of all the UM IP gateways in the Active Directory forest.

Copy Code
Get-UMIPGateway |Format-List

This example displays the properties for a UM IP gateway named MyUMIPGateway.

Copy Code
Get-UMIPGateway -Identity MyUMIPGateway

This example displays all the UM IP gateways including IP gateway simulators in the Active Directory forest.

Copy Code
Get-UMIPGateway -IncludeSimulator $true

For more information about syntax and parameters, see Get-UMIPGateway.
