Small to Medium Deployment Scenarios
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 provides sample deployments that are based on Standard Edition Server internally. The simplest topology, a Standard Edition Server, is presented first. Each subsequent topology builds upon this topology, adding functionality and the components necessary to enable it.
The following deployment scenarios are presented:
Small deployment supporting IM and conferencing for internal users only
Small deployment with support for internal and external access
Medium-sized deployment with support for external user access and voice
Medium-sized deployment with support for archiving, external access, and voice
Small Deployment Supporting IM, Presence, and Conferencing for Internal Users Only
The simplest Office Communications Server topology provides IM and conferencing internally for a small user base. It consists of a single Standard Edition Server deployment in which the Front-End, Web Conferencing, A/V Conferencing server roles, and IIS are installed on a single computer. This topology is appropriate for small to medium organizations with fewer than 5,000 users or pilot deployments in which the main goals are simplicity and ease of management and where high availability is not a requirement. The following figure shows a sample Standard Edition deployment.

Deployment Steps and Relevant Documents for this Topology
If this topology is appropriate for your organization, begin your deployment by preparing Active Directory for Office Communications Server. After you complete your Active Directory preparation, deploy a Standard Edition server, and then deploy Office Communicator 2007 and the Live Meeting 2007 client for your users.

Small Deployment with Support for External User Access
If you are deploying Office Communications Server 2007 in a small company or a pilot project and want to support IM, presence, and conferencing both for internal users and external users, build upon the Standard Edition deployment by adding an edge server to allow external user access—specifically, public IM connectivity, remote user access, federation, and the ability of external users to participate in A/V sessions and Web conferencing. For this topology, a single edge server is deployed in the perimeter network and all three edge server roles, Access Edge Server, Web Conferencing Edge Server, and A/V Edge Server are installed on a single computer. Figure 2 shows a simple deployment with support for external user access.

Deployment Steps and Relevant Documents for This Topology
If this topology is appropriate for your organization, we recommend that you deploy Office Communications Server internally first. Deploying Office Communications Server internally involves preparing Active Directory and then deploying and configuring your Standard Edition Server and deploying your clients. After your internal topology is operational, deploy the edge server. In the perimeter network, also ensure that you have a reverse HTTP proxy. This proxy will allow outside users access to meeting content, address book files and distribution group expansion information that is stored internally on the IIS server.

Medium-Sized Deployment with Support for External User Access and Voice
If you are deploying in a small to medium sized company and want to support IM, presence, and conferencing both for internal users and external users and voice functionality, build upon the simple deployment with external access, and connect your Standard Edition Server to an existing advanced media gateway. Like the simple deployment with external access described earlier in this document, a single edge server is deployed in the perimeter network, and all three edge server roles—Access Edge Server, Web Conferencing Edge Server, and A/V Edge Server—are installed on a single computer. The Standard Edition Server is connected to through an Office Communications Server Mediation Server to a media gateway for voice functionality. The following figure shows a simple deployment with support for external user access and voice.

If this topology is appropriate for your organization, we recommend that you deploy IM, presence, and Web conferencing functionality first and then deploy voice. To configure IM, presence, and conferencing, you will need to prepare Active Directory for Office Communications Server and then deploy Standard Edition Server. After your Office Communications Server is deployed, roll out your Communicator and Live Meeting clients to your end users. After your internal deployment is operational, you can deploy an edge server in your perimeter network.
In the perimeter network, also ensure that you have a reverse HTTP proxy. This proxy will allow outside users access to meeting content, address book files and distribution group expansion information that is stored internally on the IIS server (which runs on the Standard Edition Server in this topology). Once these pieces are working together, you will want to deploy enterprise voice.

Medium-Sized Deployment with External Access and Voice in Multiple Locations
If you are deploying in a medium size company and want to support the following functionality, the following topology may meet your needs:
IM, presence, and conferencing for internal users and external users
Voice functionality for multiple locations
This topology is based upon the preceding topology with a single voice location, with the addition of existing media gateway in each voice location. An Office Communications Server 2007 Mediation Server is placed between an existing media gateway to translate between the gateway and Standard Edition Server. In the advanced media gateways or the basic hybrid media gateway, the Mediation Server is not required because the logic of the Mediation Server is integrated into the gateway itself. You can find a current list of qualified gateways that work with Communications Server at https://r.office.microsoft.com/r/rlidOCS?clid=1033&p1=IPpbxVend. The following figure depicts a sample topology.

Deployment with Archiving, Communicator Web Access, External Access, and Voice in Multiple Locations
If you are deploying in a medium size company and want to support the following functionality, this sample topology may meet your needs:
IM, presence, and conferencing for internal users and external users
Voice functionality for multiple locations
Internet access to IM functionality using a Web browser
The ability to archive messages or usage data and capture call detail records
This topology is based upon the preceding topology but adds an Archiving and CDR Server to enable your company to archive instant messages and capture call data records, and a Communicator Web Access Server to provide your users with Communicator Web Access for instant messaging over secure HTTP (HTTPS). In our sample topology, the Archiving and CDR Server is collocated with its required back-end SQL database. As a variation, you could deploy the back-end SQL database on a dedicated server. Figure 5 depicts a sample topology.

If this topology is appropriate for your organization, we recommend that you deploy IM, presence, and Web conferencing functionality first and then deploy voice. To configure IM, presence and conferencing, we recommend that you deploy Office Communications Server internally and then deploy inside your perimeter network. Internally, you will need to prepare Active Directory for Office Communications Server and then deploy the Standard Edition Server and the Archiving and CDR Server. Finally, roll out your Communicator and Live Meeting clients to your end users.
Next, deploy your edge server in the perimeter network, and ensure that you have a reverse HTTP proxy. This proxy will allow outside users access to meeting content, address book files and distribution group expansion information that is stored internally on the IIS server, which in this topology runs on the Standard Edition Server. You can deploy Communicator Web Access independently of your client deployment, but your Office Communications Server 2007 infrastructure must be in place.
Once these pieces are working together, you will want to deploy Enterprise Voice.
