What method should I take to detect a dropped call? ie: User X calls user Y, user Y answers. Then user Y refreshes their browser, or closes browser all together. Is there a reconnection handler I could access somewhere to timeout the call & cleanup user X’s UI (close modal, etc etc)?

Thanks

@ccarithe1,

The best bet would be to utilize the `onReconnecting()` [event handler](https://sendbird.com/docs/calls/v1/javascript/guides/key-functions#2-add-event-handlers).

With that you could implement some logic client side to timeout the connection after sitting in the reconnected state for a certain period of time.

Ok thanks @Tyler, the call to that handler seems a bit random but I’ll try to figure something out. I’ve got a follow up question. I’m using sendbird-calls sdk v1.5.1, and after making the call camera/microphone is still being used, even after calling `call.end()`. Both hardware camera indicator and browsers software are active. Tested both on Firefox and Chrome. Should anything besides .end() be called on the call object to stop video/audio?

If you’re calling the `useMedia()` method, but are not disposing of it, you’d see similar behavior.

So if you’re doing something like

```javascript
let media = SendBirdCall.useMedia({ audio: true, video: false });

```

You’d need to ensure you call

```javascript
media.dispose();

```
