The Meeting Server includes a Recording facility and a Streaming facility. Only enable the Recorder/Streamer on the same server as the Call Bridge if you are simply evaluating the features. For normal deployment enable the Recorder/Streamer on a different server to the Call Bridge. If you intend to deploy the Recorder and Streamer on the same Meeting Server, you will need to size the server appropriately for both uses. See Chapter 11 for more information on recording and Chapter 12 for more information on streaming.
