is there a way to know that the agent disconnected from the client because the process crashes ? is any event sent?

Thanks for reaching out, Paolo. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.


Absolutely! LiveKit makes it pretty straightforward to detect when an agent disconnects, even if it’s because of something like a process crash:

• *Agent Session Close Event:* The `close` event on the agent session lets you know when a disconnection happens. The `CloseEvent` can tell you why, with reasons like `ERROR` (which might mean a crash), `PARTICIPANT_DISCONNECTED`, or `USER_INITIATED`.
• *Participant Disconnection Events:* You can keep an eye on `participantDisconnected` events to spot when anyone, including agents, leaves the room. The `DisconnectReason` gives you more clues, like `UNKNOWN_REASON` or `SIGNAL_CLOSE`.
Putting these together, you’ll have a solid way to track and handle agent disconnections. If you want, I’m here to help you set it up!
