Product version: Microsoft Office Communications Server 2007 R2
Check out the following figure. That’s no illusion-it’s an Office Communicator user communicating with a Gmail user.
If you can’t wait to try this, you have come to the right place. Before you start, ensure that the following requirements are met:
- Your organization has a properly configured Office Communications Server 2007 R2 environment.
- There is a properly configured Edge Server in your Office Communications Server environment.
- You have permissions to request a server certificate from a public or private CA.
- You have permissions to create DNS SRV and A records on the Internet.
- There is a server that is running Windows Server 2008 on which to install the XMPP Gateway in your network perimeter.
The rest of this article assumes that you have an environment running Office Communications Server 2007 R2 complete with an Edge Server (see requirements 1 and 2 in the previous list) that is configured to allow internal users to federate with external domains. You will have to request a certificate for your XMPP Gateway (requirement 3). For Gmail to locate your XMPP Gateway, you will have to create SRV and A records on your public facing DNS (requirement 4). To install the XMPP Gateway, you must have a separate server running Windows Server 2008 (requirement 5).
Figure 2 illustrates the topology of the configuration that you will be setting up. Because the XMPP Gateway connects directly to your Edge Server and the Gmail gateways on the Internet, it should be deployed in the network perimeter. Let’s get started!
