# Jitsi in Riot
|
|
|
|
Riot uses [Jitsi](https://jitsi.org/) for conference calls, which provides options for
|
|
self-hosting your own server and supports most major platforms.
|
|
|
|
1:1 calls, or calls between you and one other person, do not use Jitsi. Instead, those
|
|
calls work directly between clients or via TURN servers configured on the respective
|
|
homeservers.
|
|
|
|
There's a number of ways to start a Jitsi call: the easiest way is to click on the
|
|
voice or video buttons near the message composer in a room with more than 2 people. This
|
|
will add a Jitsi widget which allows anyone in the room to join.
|
|
|
|
Integration managers (available through the 4 squares in the top right of the room) may
|
|
provide their own approaches for adding Jitsi widgets.
|
|
|
|
## Configuring Riot to use your self-hosted Jitsi server
|
|
|
|
Riot will use the Jitsi server that is embedded in the widget, even if it is not the
|
|
one you configured. This is because conference calls must be held on a single Jitsi
|
|
server and cannot be split over multiple servers.
|
|
|
|
However, you can configure Riot to *start* a conference with your Jitsi server by adding
|
|
to your [config](./config.md) the following:
|
|
```json
|
|
{
|
|
"jitsi": {
|
|
"preferredDomain": "your.jitsi.example.org"
|
|
}
|
|
}
|
|
```
|
|
|
|
The default is `jitsi.riot.im` (a free service offered by Riot), and the demo site for
|
|
Jitsi uses `meet.jit.si` (also free).
|
|
|
|
Once you've applied the config change, refresh Riot and press the call button. This
|
|
should start a new conference on your Jitsi server.
|
|
|
|
**Note**: The widget URL will point to a `jitsi.html` page hosted by Riot. The Jitsi
|
|
domain will appear later in the URL as a configuration parameter.
|
|
|
|
**Hint**: If you want everyone on your homeserver to use the same Jitsi server by
|
|
default, set the following on your homeserver's `/.well-known/matrix/client` config:
|
|
```json
|
|
{
|
|
"im.vector.riot.jitsi": {
|
|
"preferredDomain": "your.jitsi.example.org"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Mobile app support
|
|
|
|
Currently the Riot mobile apps do not support custom Jitsi servers and will instead
|
|
use the default `jitsi.riot.im` server. When users on the mobile apps join the call,
|
|
they will be joining a different conference which has the same name, but not the same
|
|
participants. This is a known bug and which needs to be fixed.
