 allows the homeserver to generate credentials that are valid for use on the
 TURN server through the use of a secret shared between the homeserver and the
 TURN server.</p>
-<p>The following sections describe how to install <a href="https://github.com/coturn/coturn">coturn</a> (which implements the TURN REST API) and integrate it with synapse.</p>
+<p>This documentation provides two TURN server configuration examples:</p>

+<p>For TURN relaying to work, the TURN service must be hosted on a server/endpoint with a public IP.</p>
 <p>Hosting TURN behind NAT requires port forwaring and for the NAT gateway to have a public IP.
 However, even with appropriate configuration, NAT is known to cause issues and to often not work.</p>
-<h2 id="coturn-setup"><a class="header" href="#coturn-setup"><code>coturn</code> setup</a></h2>
-<h3 id="initial-installation"><a class="header" href="#initial-installation">Initial installation</a></h3>
-<p>The TURN daemon <code>coturn</code> is available from a variety of sources such as native package managers, or installation from source.</p>
-<h4 id="debian-installation"><a class="header" href="#debian-installation">Debian installation</a></h4>
-<p>Just install the debian package:</p>
-<pre><code class="language-sh">apt install coturn
-</code></pre>
-<p>This will install and start a systemd service called <code>coturn</code>.</p>
-<h4 id="source-installation"><a class="header" href="#source-installation">Source installation</a></h4>
-<ol>
-<li>
-<p>Download the <a href="https://github.com/coturn/coturn/releases/latest">latest release</a> from github.  Unpack it and <code>cd</code> into the directory.</p>
-</li>
-<li>
-<p>Configure it:</p>
-<pre><code class="language-sh">./configure
-</code></pre>
-<p>You may need to install <code>libevent2</code>: if so, you should do so in
-the way recommended by your operating system. You can ignore
-warnings about lack of database support: a database is unnecessary
-for this purpose.</p>
-</li>
-<li>
-<p>Build and install it:</p>
-<pre><code class="language-sh">make
-make install
-</code></pre>
-</li>
-</ol>
-<h3 id="configuration"><a class="header" href="#configuration">Configuration</a></h3>
-<ol>
-<li>
-<p>Create or edit the config file in <code>/etc/turnserver.conf</code>. The relevant
-lines, with example values, are:</p>
-<pre><code>use-auth-secret
-static-auth-secret=[your secret key here]
-realm=turn.myserver.org
-</code></pre>
-<p>See <code>turnserver.conf</code> for explanations of the options. One way to generate
-the <code>static-auth-secret</code> is with <code>pwgen</code>:</p>
-<pre><code class="language-sh">pwgen -s 64 1
-</code></pre>
-<p>A <code>realm</code> must be specified, but its value is somewhat arbitrary. (It is
-sent to clients as part of the authentication flow.) It is conventional to
-set it to be your server name.</p>
-</li>
-<li>
-<p>You will most likely want to configure coturn to write logs somewhere. The
-easiest way is normally to send them to the syslog:</p>
-<pre><code class="language-sh">syslog
-</code></pre>
-<p>(in which case, the logs will be available via <code>journalctl -u coturn</code> on a
-systemd system). Alternatively, coturn can be configured to write to a
-logfile - check the example config file supplied with coturn.</p>
-</li>
-<li>
-<p>Consider your security settings. TURN lets users request a relay which will
-connect to arbitrary IP addresses and ports. The following configuration is
-suggested as a minimum starting point:</p>
-<pre><code># VoIP traffic is all UDP. There is no reason to let users connect to arbitrary TCP endpoints via the relay.
-no-tcp-relay
-
-# don't let the relay ever try to connect to private IP address ranges within your network (if any)
-# given the turn server is likely behind your firewall, remember to include any privileged public IPs too.
-denied-peer-ip=10.0.0.0-10.255.255.255
-denied-peer-ip=192.168.0.0-192.168.255.255
-denied-peer-ip=172.16.0.0-172.31.255.255
-
-# recommended additional local peers to block, to mitigate external access to internal services.

-<p>Also consider supporting TLS/DTLS. To do this, add the following settings
-to <code>turnserver.conf</code>:</p>
-<pre><code># TLS certificates, including intermediate certs.
-# For Let's Encrypt certificates, use `fullchain.pem` here.
-cert=/path/to/fullchain.pem
-
-# TLS private key file
-pkey=/path/to/privkey.pem
-
-# Ensure the configuration lines that disable TLS/DTLS are commented-out or removed
-#no-tls
-#no-dtls
-</code></pre>
-<p>In this case, replace the <code>turn:</code> schemes in the <code>turn_uris</code> settings below
-with <code>turns:</code>.</p>
-<p>We recommend that you only try to set up TLS/DTLS once you have set up a
-basic installation and got it working.</p>
-<p>NB: If your TLS certificate was provided by Let's Encrypt, TLS/DTLS will
-not work with any Matrix client that uses Chromium's WebRTC library. This
-currently includes Element Android &amp; iOS; for more details, see their
-<a href="https://github.com/vector-im/element-android/issues/1533">respective</a>
-<a href="https://github.com/vector-im/element-ios/issues/2712">issues</a> as well as the underlying
-<a href="https://bugs.chromium.org/p/webrtc/issues/detail?id=11710">WebRTC issue</a>.
-Consider using a ZeroSSL certificate for your TURN server as a working alternative.</p>
-</li>
-<li>
-<p>Ensure your firewall allows traffic into the TURN server on the ports
-you've configured it to listen on (By default: 3478 and 5349 for TURN
-traffic (remember to allow both TCP and UDP traffic), and ports 49152-65535
-for the UDP relay.)</p>
-</li>
-<li>
-<p>If your TURN server is behind NAT, the NAT gateway must have an external,
-publicly-reachable IP address. You must configure coturn to advertise that
-address to connecting clients:</p>
-<pre><code>external-ip=EXTERNAL_NAT_IPv4_ADDRESS
-</code></pre>
-<p>You may optionally limit the TURN server to listen only on the local
-address that is mapped by NAT to the external address:</p>
-<pre><code>listening-ip=INTERNAL_TURNSERVER_IPv4_ADDRESS
-</code></pre>
-<p>If your NAT gateway is reachable over both IPv4 and IPv6, you may
-configure coturn to advertise each available address:</p>
-<pre><code>external-ip=EXTERNAL_NAT_IPv4_ADDRESS
-external-ip=EXTERNAL_NAT_IPv6_ADDRESS
-</code></pre>
-<p>When advertising an external IPv6 address, ensure that the firewall and
-network settings of the system running your TURN server are configured to
-accept IPv6 traffic, and that the TURN server is listening on the local
-IPv6 address that is mapped by NAT to the external IPv6 address.</p>
-</li>
-<li>
-<p>(Re)start the turn server:</p>
-<ul>
-<li>
-<p>If you used the Debian package (or have set up a systemd unit yourself):</p>
-<pre><code class="language-sh">systemctl restart coturn

-<li>&quot;<code>turn_uris</code>&quot;: This needs to be a yaml list of public-facing URIs
-for your TURN server to be given out to your clients. Add separate
-entries for each transport your TURN server supports.</li>
-<li>&quot;<code>turn_shared_secret</code>&quot;: This is the secret shared between your
-homeserver and your TURN server, so you should set it to the same
-string you used in turnserver.conf.</li>
-<li>&quot;<code>turn_user_lifetime</code>&quot;: This is the amount of time credentials
-generated by your homeserver are valid for (in milliseconds).
-Shorter times offer less potential for abuse at the expense of
-increased traffic between web clients and your homeserver to
-refresh credentials. The TURN REST API specification recommends
-one day (86400000).</li>
-<li>&quot;<code>turn_allow_guests</code>&quot;: Whether to allow guest users to use the
-TURN server. This is enabled by default, as otherwise VoIP will
-not work reliably for guests. However, it does introduce a
-security risk as it lets guests connect to arbitrary endpoints
-without having gone through a CAPTCHA or similar to register a
