In ARI, event filtering isn’t done through ari.conf like in manager.conf. Instead, it’s controlled through the WebSocket connection. If you use subscribeAll=true, you’ll get everything — so to filter events, just skip that and subscribe only to the specific channels, bridges, or endpoints you care about. You can also handle filtering inside your app by ignoring the events you don’t need. It’s more of an API-level control than something set in the config file.
