The Streamer should be hosted on another Meeting Server instance than the server hosting the Call Bridge. If the Streamer is hosted on the same server as the Call Bridge (local), then it should only be used for testing purposes.
Where possible, it is recommended that the Streamer is deployed in the same physical locality as the Call Bridge to ensure low latency and high network bandwidth. If there are network connection issues between the Call Bridge and the Streamer, then the resultant stream could be affected.
For more information on using the Streamer, see the deployment guide relevant to your setup.
