Organization administrators can also change the organization's video chat provider. ### Change your organization's video chat provider {start_tabs} {tab|jitsi-meet} Zulip's default video chat provider is [Jitsi Meet](https://meet.jit.si). You can also use Zulip with Jitsi Meet on-premise; to configure this, just set `JITSI_SERVER_URL` in `/etc/zulip/settings.py`. {tab|bigbluebutton} Using Big Blue Button as a video chat provider is currently only possible on self-hosted Zulip installations. See the [detailed configuration instructions][big-blue-button-configuration]. {tab|zoom} Zulip supports Zoom as the video chat provider using an OAuth integration. You can set it up as follows: {settings_tab|organization-settings} 1. Under **Other settings** set **Video chat provider** to **Zoom**. 1. Click **Save changes**. Any user who creates a video call link using the instructions above will be prompted to link a Zoom account with their Zulip account. If you would like to unlink Zoom from your Zulip account: 1. Log in to the [Zoom App Marketplace](https://marketplace.zoom.us/). 1. Click **Manage** → **Installed Apps**. 1. Click the **Uninstall** button next to the Zulip app. If you are self-hosting, you will need to [create a Zoom application][zoom-configuration] to use this integration. {tab|disable} You can also disable the video call button for your organization by setting the provider to "None". {end_tabs} [big-blue-button-configuration]: https://zulip.readthedocs.io/en/latest/production/video-calls.html#big-blue-button [zoom-configuration]: https://zulip.readthedocs.io/en/latest/production/video-calls.html#zoom
