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


Just a quick heads-up: the `await session.close()` method isn’t the way to end a call in LiveKit. Instead, you’ll want to use `await session.aclose()`—that’s the asynchronous method designed to close a session properly. This is the best way to wrap up your call.
If you have any questions or want some examples, don’t hesitate to ask—I’m here to help!

Yep, calling `session.aclose()` will close the call in LiveKit by ending the session and freeing up all the resources tied to it. It’s the right way to wrap up a call through code.
If you want me to explain more or share some examples, just give me a shout!
