Create a UM IP Gateway

To configure the UM Service to be used with Lync Server 2013 Microsoft has a script that will create and configure all necessary components. This scripts is located in the scripts directory C:\Program Files\Microsoft\Exchange Server\V15\Scripts.

In the Exchange Management Shell run the following commands:
• .\ExchUCUtil.ps1

This script does the following:

  • Grants Lync Server permission to read Exchange UM Active Directory components, specifically, the SIP URI dial plan that was created in the first step.
  • Creates a UM IP gateway for each Lync Server pool that hosts users who will be enabled for Enterprise Voice.
  • Create an Exchange UM hunt group for each UM IP gateway. The hunt group pilot identifier will be the name of the dial plan associated with the corresponding UM IP gateway. The hunt group must specify the UM SIP dial plan used with the UM IP gateway.
  • When the script has run you’ll see a new UM IP Gateway appear in the EAC. Since this script not only creates the UM IP Gateway but also sets the necessary permissions the UM IP Gateway was not created manually in the first step.

The next step is to run the OcsUmUtil.exe utility which creates the contact objects for Outlook Voice Access and for the auto attendants. This tool can be found in C:\Program Files\Common Files\Microsoft Lync Server 2013\Support.

Hope it helps.
