| If you want to use Microsoft Exchange Server Unified Messaging (UM) to provide call answering, Outlook Voice Access, or auto-attendant services for Enterprise Voice users, read the information in “On-Premises Exchange Unified Messaging Integration” in the Planning documentation, and then follow the instructions in this section. |
Configuring Exchange Server Unified Messaging to work with Enterprise Voice consists of the following tasks:
- Configuring certificates on the server running Microsoft
Exchange Server Unified Messaging
- Creating one or more UM SIP URI dial plans, along with their
subscriber access phone numbers as needed, and then creating
corresponding Lync Server dial plans
- Using the exchucutil.ps1 script to:
- Create UM IP gateways.
- Create UM hunt groups.
- Grant Lync Server permission to read UM Active Directory Domain
Services (AD DS) objects.
- Create UM IP gateways.
- Creating a UM auto-attendant object
- Creating a subscriber access object
- Creating a SIP URI for each user and associating users with a
UM SIP URI dial plan
Requirements and
Recommendations
Before you begin, the documentation in this section assumes that you have deployed the following Exchange server roles: Hub Transport, Client Access, Mailbox, and Unified Messaging.
For details about deploying Microsoft Exchange Server 2007 Service Pack 1 (SP1), see the Exchange Server 2007 TechNet Library at http://go.microsoft.com/fwlink/?LinkID=129672.
For details about deploying Microsoft Exchange Server 2010, see the Exchange Server 2010 TechNet Library at http://go.microsoft.com/fwlink/?LinkID=186202.
Also note the following:
- If Exchange UM is installed in multiple forests, the Exchange
integration steps must be performed for each UM forest. In
addition, each UM forest must be configured to trust the forest in
which Lync Server is deployed, and the forest in which Lync Server
is deployed must be configured to trust each UM forest.
- Integration steps are performed on both the server running
Exchange Server Unified Messaging and the server running Lync
Server. You should perform the Exchange Server Unified Messaging
integration steps before you perform the Lync Server integration
steps.
Note:To see which integration steps are performed on which servers and by which administrator roles, see Deployment Process for Integrating On-Premises Unified Messaging and Lync Server 2010.
The following tools must be available on each server running Exchange UM:
- Exchange Management Shell
- The script exchucutil.ps1, which performs the following
tasks:
- Creates a UM IP gateway for each Lync Server.
- Creates a hunt group for each gateway. The pilot identifier of
each hunt group specifies the UM SIP URI dial plan used by the
Front End pool or Standard Edition server that is associated with
the gateway.
- Grants Lync Server permission to read Exchange UM objects in
Active Directory Domain Services (AD DS).
- Creates a UM IP gateway for each Lync Server.
