Chapter 3: Deploying Enterprise Voice

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

This section guides you through the deployment of Microsoft® Office Communications Server 2007 Enterprise Voice. Typically you deploy Enterprise Voice as the final step in your Office Communications Server 2007 deployment. For recommended deployment scenarios, see Select a Deployment Option in Office Communications Server. For information about planning your Enterprise Voice deployment, see Chapter 2: Planning for Enterprise Voice.

Prerequisites

For an optimum experience when deploying Enterprise Voice, make sure that your IT infrastructure, network, and systems meet the following prerequisites:

  • Microsoft Office Communications Server 2007 Standard Edition or Enterprise Edition is installed and operational on your network.

  • All edge servers are deployed and operational in your perimeter network, including Access Edge Server, Audio/Video Conferencing Edge Server, Web Conferencing Edge Server, and a reverse proxy.

  • Exchange Server 2007 SP1 is required for integrating Exchange Unified Messaging with Office Communications Server.

  • One or more users have been created and enabled for Office Communications Server 2007.

  • A primary phone number has been designated, normalized, and copied to the msRTCSIP-line attribute for each user who is to be enabled for Enterprise Voice. The administrator is responsible for ensuring that this number is unique.

  • Administrators deploying Enterprise Voice should be members of the RTCUniversalServerAdmins group.

  • Office Communicator 2007 and Live Meeting 2007 are successfully deployed.

  • MKI (Managed Key Infrastructure) is deployed and configured, using either a Microsoft or a third-party CA (certification authority) infrastructure.

  • Each computer on which you install Mediation Server must be:

    • Running Microsoft Windows Server 2003 Service Pack 1.

    • Prepped for Active Directory. For Active Directory prep procedures, see Office Communications Server 2007 Active Directory Guide.

  • One or more media gateways are available for deployment.

Choosing Your Deployment Path

The recommended sequence of steps for deploying Enterprise Voice varies according to whether you plan to deploy Office Communications Server with PBX integration and, if not, whether you intend to use Exchange Server 2007 SP1 Unified Messaging to provide call answering, Outlook Voice Access, and auto-attendant services.

The following figure summarizes the recommended deployment path for Enterprise Voice:
