Use the New UM IP Gateway Wizard to create a new UM IP gateway for use by Microsoft Exchange Server 2007 Unified Messaging (UM). A UM IP gateway establishes a logical link between the IP gateway device, a UM IP gateway, and single or multiple UM hunt groups.
A UM IP gateway is created by using an organization-wide scope and is a container object that logically represents a physical IP gateway hardware device. Before the IP gateway device can process Unified Messaging calls, the IP gateway must be represented by an object in the Active Directory directory service and then associated with one or more UM dial plans.
After a UM IP gateway is created, you may have to create and associate a UM hunt group with a UM dial plan. For more information about how to create a UM hunt group, see How to Create a New Unified Messaging Hunt Group.
After a UM IP gateway is created, you may also have to enable users for Unified Messaging. For more information about how to enable users for Unified Messaging, see How to Enable a User for Unified Messaging.
New IP Gateway Wizard
To create a new UM IP gateway, in the New UM IP Gateway Wizard, on the New page, complete the following information:
- UM IP gateway name
-
- Use this text box to specify a unique name for the UM IP
gateway. This is a display name that appears in the Exchange
Management Console. If you must change the display name of the UM
IP gateway after it has 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 is 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 is 64 characters, and it can include spaces.

- IP Address
-
- Use this text box to enter the IPv4 address for the IP gateway
or Session Initiation Protocol (SIP)–enabled Private Branch
eXchange (PBX). This is the IP address that is configured on the
network or LAN interface of the IP gateway or SIP-enabled PBX. You
can change the IP address after the UM IP gateway has been created.
However, changing this setting may disrupt communication between
Unified Messaging servers and the IP gateway or SIP-enabled IP/PBX.
Modifications to a UM IP gateway should be performed only by an
administrator who fully understands the implications of making
configuration changes to the UM IP gateway. This text box will
accept only IP addresses that are valid and formatted
correctly.
- This field can accept an IPv6 address; however, IPv6 is not
supported in this release of the product.
- Use this text box to enter the IPv4 address for the IP gateway
or Session Initiation Protocol (SIP)–enabled Private Branch
eXchange (PBX). This is the IP address that is configured on the

- Fully qualified domain name (FQDN)
-
- Use this text box to enter the FQDN for the UM IP gateway. This
is the FQDN that is configured on a host record for the UM IP
gateway in the DNS forward lookup zone on the authoritative DNS
server.
- This text box will accept only fully qualified domain names
(FQDNs) that are valid and formatted correctly.

gateway in the DNS forward lookup zone on the authoritative DNS
server.
- 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 do not 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. After you associate the UM IP
gateway with a UM dial plan, the IP gateway will answer incoming
calls.

After you complete the text boxes on this page of the New UM IP Gateway wizard, click New to create the new UM IP gateway.
