Configuring UM IP Gateways
You are required to create an IP gateway when you don't use OCS 2007 R2 in your environment and want to connect directly Exchange 2010 UM to your IP PBX or IP gateway. If you use OCS 2007 R2, the task of creating an IP gateway per OCS Pool will be done by the ExchUCUtil.ps1 script.
To create an UM IP gateway, you need the following information:
§ The name of the UM IP gateway
§ The IP address or FQDN of the IP gateway or IP PBX that you want to connect to
§ The UM dial plan the UM IP gateway will serve
To create a UM IP gateway, you can use the New-IPGateway cmdlet in the EMS or use the EMC as shown in Figure 1.

Configuring UM Hunt Groups
For every UM IP gateway you also need at least one UM hunt group. To create a UM hunt group you need the following information:
§ Name of the UM hunt group
§ The pilot identifier for this UM hunt group
§ The UM dial plan the UM hunt group is part of
You can create the UM hunt group in the EMC, as shown in Figure 2, or you can use the New-UMHuntGroup cmdlet.
