Zulip supports using BigBlueButton as its video call video call provider. This is currently only possible on self-hosted Zulip installations. To use the [BigBlueButton](https://bigbluebutton.org/) video call integration, you'll need to have a BigBlueButton server and configure your zulip server to use that BigBlueButton server. ### Configure BigBlueButton server 1. Get the Shared Secret using the `bbb-conf --secret` command on your BigBlueButton Server. See also [BigBlueButton documentation](https://docs.bigbluebutton.org/admin/customize.html#extract-the-shared-secret). 1. Get the URL to your BigBlueButton API. The URL has the form of `https://bigbluebutton.example.com/bigbluebutton/` and can also be found using the `bbb-conf --secret` command. ### Configure zulip server 1. In `/etc/zulip/zulip-secrets.conf`, set `big_blue_button_secret` as your BigBlueButton Server's shared secret. 1. In `/etc/zulip/settings.py`, set `BIG_BLUE_BUTTON_URL` as your BigBlueButton Server's API URL. 1. Restart the Zulip server with `/home/zulip/deployments/current/scripts/restart-server`. ### Using BigBlueButton 1. Select BigBlueButton as the organization's [video call provider](/help/start-a-call#changing-your-organizations-video-call-provider). 1. Zulip's [call button](/help/start-a-call) will now create meetings using BigBlueButton.
