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 Exchange Unified Messaging Integration 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 Communications Server dial plans
- Using the exchucutil.ps1 script to:
- Create UM IP gateways.
- Create UM hunt groups.
- Grant Communications Server permission to read UM Active
Directory Domain Services 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 product documentation at http://go.microsoft.com/fwlink/?LinkID=129672.
For details about deploying Microsoft Exchange Server 2010, see the product documentation 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 Communications Server is deployed, and the forest in which
Communications 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
Communications Server. You should perform the Exchange Server
Unified Messaging integration steps before you perform the
Communications Server integration steps.
Note: To see which integration steps are performed on which servers and by which administrator roles, see Deployment Process for Integrating Unified Messaging and Communications Server.
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 Communications 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
Enterprise pool or Standard Edition Server that is associated with
the gateway.
- Grants Communications Server permission to read Exchange UM
objects in Active Directory Domain Services.
- Creates a UM IP gateway for each Communications Server.
