# Use BigBlueButton as your call provider in Zulip
You can configure BigBlueButton as the call provider for your organization.
Users will be able to start a BigBlueButton call and invite others using the
**add video call** () or
**add voice call** () button
[in the compose box](/help/start-a-call).
!!! warn ""
**Note:** This is currently only possible on self-hosted Zulip
installations, and you'll need a BigBlueButton server.
## Configure BigBlueButton as your call provider
By default, Zulip integrates with
[Jitsi Meet](https://jitsi.org/jitsi-meet/), a fully-encrypted, 100% open
source video conferencing solution. You can configure Zulip to use BigBlueButton
as your call provider instead.

BigBlueButton server's shared secret.

BigBlueButton server's hostname.
