I was very surprised by the fact that a rather important configuration for coturn was "hidden" in the Hosts file, but not mentioned here. Therefore my suggestion is to explicitly mention it here, as I believe that is that natural for people to look.

# TURN server
|
|
|
|
The playbook installs a [Coturn](https://github.com/coturn/coturn) TURN server by default, so that clients can make audio/video calls even from [NAT](https://en.wikipedia.org/wiki/Network_address_translation)-ed networks.
|
|
|
|
By default, the Synapse chat server is configured, so that it points to the Coturn TURN server installed by the playbook.
|
|
|
|
|
|
## Disabling Coturn
|
|
|
|
If, for some reason, you'd like to prevent the playbook from installing Coturn, you can use the following configuration:
|
|
|
|
```yaml
|
|
matrix_coturn_enabled: false
|
|
```
|
|
|
|
In that case, Synapse would not point to any Coturn servers and audio/video call functionality may fail.
|
|
|
|
## Manually defining your public IP
|
|
In the `hosts` file we explicitly ask for your server's external IP address when defining `ansible_host`, because the same value is used for configuring Coturn.
|
|
If you'd rather use a local IP for `ansible_host`, make sure to set up `matrix_coturn_turn_external_ip_address` replacing `YOUR_PUBLIC_IP` with the pubic IP used by the server.
|
|
|
|
```yaml
|
|
matrix_coturn_turn_external_ip_address: "YOUR_PUBLIC_IP"
|
|
```
|
|
|
|
## Using your own external Coturn server
|
|
|
|
If you'd like to use another TURN server (be it Coturn or some other one), you can configure the playbook like this:
|
|
|
|
```yaml
|
|
# Disable integrated Coturn server
|
|
matrix_coturn_enabled: false
|
|
|
|
# Point Synapse to your other Coturn server
|
|
matrix_synapse_turn_uris:
|
|
- turns:HOSTNAME_OR_IP?transport=udp
|
|
- turns:HOSTNAME_OR_IP?transport=tcp
|
|
- turn:HOSTNAME_OR_IP?transport=udp
|
|
- turn:HOSTNAME_OR_IP?transport=tcp
|
|
```
|
|
|
|
If you have or want to enable [Jitsi](configuring-playbook-jitsi.md), you might want to enable the TURN server there too.
|
|
If you do not do it, Jitsi will fall back to an upstream service.
|
|
|
|
```yaml
|
|
jitsi_web_stun_servers:
|
|
- stun:HOSTNAME_OR_IP:PORT
|
|
```
|
|
You can put multiple host/port combinations if you like.
