Deploying
IBM® Sametime® consists of a variety of servers and clients, and can be deployed to suit many different environments. The deployment instructions are organized by feature set, beginning with the minimum components that are necessary to support instant messaging, and then expanding the deployment to include features such as audio and video support, and conferencing.
Deploying an instant messaging gateway for external communities
Clients in a local IBM® Sametime® community can communicate with users in other communities through the Sametime Gateway.
Connecting servers to Sametime® Gateway
To complete IBM® Sametime® Gateway Server setup, you connect servers to the Sametime Gateway Server by performing some configuration steps on the local Sametime server, adding the local community to the Sametime Gateway Server, registering your Sametime Gateway server with AOL so that Sametime Gateway Server can connect to the AOL clearinghouse, and then, after you complete your registration, adding the AOL clearinghouse community to the Sametime Gateway Server. Finally, you want to note the port numbers so you can provide these ports to external communities.
Connecting to external Sametime® communities
Connect to external Sametime® communities by working, if necessary, with an administrator from an external community to prepare the external Sametime server and by then adding the external Sametime community to your list of communities.
Preparing external Sametime® servers
This topic presents general information on steps needed to configure Sametime® servers versions 6.5.1 or 7.0 that exist in external communities. Work with the external community's administrator to prepare the legacy Sametime server for Sametime Gateway communications. For example, if your local Sametime server is a member of widgets.com, and you want to connect to an external Sametime 6.5.1 server at acme.com, you may want to know the steps required to set up the external Sametime server to have instant messaging and presence with your Sametime Gateway Server.

Procedure

If the external community's Sametime server is version 6.5.1, or 7.0, the external community must enable the Sametime SIP Gateway on the server. See the chapter "Enabling the SIP Gateway" in the Sametime 7.0 Administrator's Guide.
The latest patches and Cumulative Fix Packs must be installed on the external community's Sametime server. Go to Sametime Product Support to download the latest support files for the external Sametime server.
