how to gracefull delete room when user hangs up and RoomInputOptions.close_on_disconnect=False

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


When a user hangs up and `RoomInputOptions.close_on_disconnect` is set to `False`, you’ll want to manually delete the room to keep everything running smoothly. Here’s a simple way to handle it:

1. First, detect when the user hangs up using callbacks or events.
2. Next, make sure any ongoing agent speech finishes by calling `wait_for_playout()`.
3. Finally, use the `delete_room` API through the LiveKit server to close the room for everyone involved.
This method helps keep your rooms neat and tidy, avoiding problems like participants sticking around or extra audio in recordings. If you’d like, I’m here to help you implement this step-by-step—just let me know!
