msgid "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."
msgid "If, for some reason, you'd like to prevent the playbook from installing Coturn, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:"
msgid "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."
msgid "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."
msgid "If you'd like to rely on external IP address auto-detection (not recommended unless you need it), set `matrix_coturn_turn_external_ip_address` to an empty value. The playbook will automatically contact an [EchoIP](https://github.com/mpolden/echoip)-compatible service (`https://ifconfig.co/json` by default) to determine your server's IP address. This API endpoint is configurable via the `matrix_coturn_turn_external_ip_address_auto_detection_echoip_service_url` variable."
msgid "The playbook uses the [`auth-secret` authentication method](https://github.com/coturn/coturn/blob/873cabd6a2e5edd7e9cc5662cac3ffe47fe87a8e/README.turnserver#L186-L199) by default, but you may switch to the [`lt-cred-mech` method](https://github.com/coturn/coturn/blob/873cabd6a2e5edd7e9cc5662cac3ffe47fe87a8e/README.turnserver#L178) which [some report](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3191) to be working better."
msgid "If you're using [Jitsi](./configuring-playbook-jitsi.md), note that switching to `lt-cred-mech` will remove the integration between Jitsi and your own Coturn server, because Jitsi only seems to support the `auth-secret` authentication method."
msgid "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."
