The following are guidelines and best practices that you should consider when deploying Enterprise Voice:
- Deploy a Microsoft Communications Server 2010 Standard Edition
server or Enterprise pool. For details about installation
information, see Deploying Communications
Server 2010 (Beta Refresh).
- Work with Exchange administrators to confirm which tasks each
of you will perform to assure a smooth and successful
- Deploy the Exchange Mailbox, Hub Transport, Client Access, and
Unified Messaging server roles in each forest where you want to
enable users for Exchange Unified Messaging (UM). For details about
installing Exchange server roles, see topics in the Deployment section of the Microsoft Exchange Server
Important: When Exchange Unified Messaging (UM) is installed, it is configured to use a self-signed certificate.
Do not delete the self-signed certificate. Without it, Exchange UM cannot communicate with other Exchange server roles including the Hub Transport Server, which sends voice mail notifications.
The self-signed certificate, however, does not enable Communications Server and Exchange UM to trust each other, which is why it is necessary to request a separate certificate from a CA that both servers trust.
Important: We recommend that you deploy a minimum of two Exchange UM servers for each Exchange UM SIP URI dial plan that you configure for your organization. In addition to providing expanded capacity, deploying redundant Exchange UM servers provides high availability. In the event of an Exchange UM server failure, Communications Server automatically fails over to the other server.
- If Communications Server and Exchange UM are installed in
different forests, configure each Exchange forest to trust the
Communications Server forest and the Communications Server forest
to trust each Exchange forest. Also, set the users’ Exchange UM
settings on the user objects in the Communications Server forest.
This is typically done by using a script or a cross-forest tool
such as MIIS.
- If necessary, install the Exchange Management Console to manage
your Unified Messaging servers.
Note: The Exchange Management Console cannot be installed on any computers where an Exchange server role has been installed.
- Obtain valid phone numbers for Outlook Voice Access and auto
- Coordinate names for Exchange UM SIP URI dial plans and
Enterprise Voice dial plans.
