+# Continuwuity v0.5.5 (2026-02-15)
+
+## Features
+
+- Added unstable support for [MSC4406:
+  `M_SENDER_IGNORED`](https://github.com/matrix-org/matrix-spec-proposals/pull/4406).
+  Contributed by @nex ([#1308](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1308))
+- Introduce a resolver command to allow flushing a server from the cache or to flush the complete cache. Contributed by
+  @Omar007 ([#1349](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1349))
+- Improved the handling of restricted join rules and improved the performance of local-first joins. Contributed by
+  @nex. ([#1368](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1368))
+- You can now set a custom User Agent for URL previews; the default one has been modified to be less likely to be
+  rejected. Contributed by @trashpanda ([#1372](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1372))
+- Improved the first-time setup experience for new homeserver administrators:
+    - Account registration is disabled on the first run, except for with a new special registration token that is logged
+      to the console.
+    - Other helpful information is logged to the console as well, including a giant warning if open registration is
+      enabled.
+    - The default index page now says to check the console for setup instructions if no accounts have been created.
+    - Once the first admin account is created, an improved welcome message is sent to the admin room.
+
+  Contributed by @ginger.
+
+## Bugfixes
+
+- Fixed invites sent to other users in the same homeserver not being properly sent down sync. Users with missing or
+  broken invites should clear their client caches after updating to make them appear. ([#1249](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1249))
+- LDAP-enabled servers will no longer have all admins demoted when LDAP-controlled admins are not configured.
+  Contributed by @Jade ([#1307](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1307))
+- Fixed sliding sync not resolving wildcard state key requests, enabling Video/Audio calls in Element X. ([#1370](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1370))
+
+## Misc
+
+- #1344
+
+# Continuwuity v0.5.4 (2026-02-08)
+
+## Features
+
+- The announcement checker will now announce errors it encounters in the first run to the admin room, plus a few other
+  misc improvements. Contributed by @Jade ([#1288](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1288))
+- Drastically improved the performance and reliability of account deactivations. Contributed by
+  @nex ([#1314](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1314))
+- Refuse to process requests for and events in rooms that we no longer have any local users in (reduces state resets
+  and improves performance). Contributed by
+  @nex ([#1316](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1316))
+- Added server-specific admin API routes to ban and unban rooms, for use with moderation bots. Contributed by @nex
+  ([#1301](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1301))
+

+  @Jade ([#1290](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1290))
+- Fixed specification non-compliance when handling remote media errors. Contributed by
+  @nex ([#1298](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1298))
+- UIAA requests which check for out-of-band success (sent by matrix-js-sdk) will no longer create unhelpful errors in
+  the logs. Contributed by @ginger ([#1305](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1305))
+- Use exists instead of contains to save writing to a buffer in `src/service/users/mod.rs`: `is_login_disabled`.
+  Contributed
+  by @aprilgrimoire. ([#1340](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1340))
+- Fixed backtraces being swallowed during panics. Contributed by
+  @jade ([#1337](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1337))
+- Fixed a potential vulnerability that could allow an evil remote server to return malicious events during the room join
+  and knock process. Contributed by @nex, reported by violet & [mat](https://matdoes.dev).
+- Fixed a race condition that could result in outlier PDUs being incorrectly marked as visible to a remote server.
+  Contributed by @nex, reported by violet & [mat](https://matdoes.dev).
+- ACLs are no longer case-sensitive. Contributed by @nex, reported by [vel](matrix:u/vel:nhjkl.com?action=chat).

 # Continuwuity 0.5.2 (2026-01-09)
 
 ## Features
 
-- Added support for issuing additional registration tokens, stored in the database, which supplement the existing registration token hardcoded in the config file. These tokens may optionally expire after a certain number of uses or after a certain amount of time has passed. Additionally, the `registration_token_file` configuration option is superseded by this feature and **has been removed**. Use the new `!admin token` command family to manage registration tokens. Contributed by @ginger (#783).
-- Implemented a configuration defined admin list independent of the admin room. Contributed by @Terryiscool160. (#1253)
-- Added support for invite and join anti-spam via Draupnir and Meowlnir, similar to that of synapse-http-antispam. Contributed by @nex. (#1263)
-- Implemented account locking functionality, to complement user suspension. Contributed by @nex. (#1266)
-- Added admin command to forcefully log out all of a user's existing sessions. Contributed by @nex. (#1271)
-- Implemented toggling the ability for an account to log in without mutating any of its data. Contributed by @nex. (#1272)
-- Add support for custom room create event timestamps, to allow generating custom prefixes in hashed room IDs. Contributed by @nex. (#1277)
-- Certain potentially dangerous admin commands are now restricted to only be usable in the admin room and server console. Contributed by @ginger.

+# Calls
+
+Matrix supports two types of calls:
+
+- Element Call powered by [MatrixRTC](https://half-shot.github.io/msc-crafter/#msc/4143) and [LiveKit](https://github.com/livekit/livekit)
+- Legacy calls, sometimes using Jitsi
+
+Both types of calls are supported by different sets of clients, but most clients are moving towards MatrixRTC / Element Call.
+
+For either one to work correctly, you have to do some additional setup.
+
+- For legacy calls to work, you need to set up a TURN/STUN server. [Read the TURN guide for tips on how to set up coturn](./calls/turn.mdx)
+- For MatrixRTC / Element Call to work, you have to set up the LiveKit backend (foci). LiveKit also uses TURN/STUN to increase reliability, so you might want to configure your TURN server first. [Read the LiveKit guide](./calls/livekit.mdx)

+# Matrix RTC/Element Call Setup
+
+:::info
+This guide assumes that you are using docker compose for deployment. LiveKit only provides Docker images.
+:::
+
+## Instructions
+
+### 1. Domain
+
+LiveKit should live on its own domain or subdomain. In this guide we use `livekit.example.com` - this should be replaced with a domain you control.
+
+Make sure the DNS record for the (sub)domain you plan to use is pointed to your server.
+
+### 2. Services
+
+Using LiveKit with Matrix requires two services - Livekit itself, and a service (`lk-jwt-service`) that grants Matrix users permission to connect to it.
+
+You must generate a key and secret to allow the Matrix service to authenticate with LiveKit. `LK_MATRIX_KEY` should be around 20 random characters, and `LK_MATRIX_SECRET` should be around 64. Remember to replace these with the actual values!
+
+:::tip Generating the secrets
+LiveKit provides a utility to generate secure random keys
+```bash
+docker run --rm livekit/livekit-server:latest generate-keys
+```
+:::
+
+```yaml
+services:
+  lk-jwt-service:
+    image: ghcr.io/element-hq/lk-jwt-service:latest
+    container_name: lk-jwt-service
+    environment:
+      - LIVEKIT_JWT_BIND=:8081
+      - LIVEKIT_URL=wss://livekit.example.com
+      - LIVEKIT_KEY=LK_MATRIX_KEY
+      - LIVEKIT_SECRET=LK_MATRIX_SECRET
+      - LIVEKIT_FULL_ACCESS_HOMESERVERS=example.com
+    restart: unless-stopped
+    ports:
+      - "8081:8081"
+
+  livekit:
+    image: livekit/livekit-server:latest
+    container_name: livekit
+    command: --config /etc/livekit.yaml
+    restart: unless-stopped
+    volumes:
+      - ./livekit.yaml:/etc/livekit.yaml:ro
+    network_mode: "host" # /!\ LiveKit binds to all addresses by default.
+    # Make sure port 7880 is blocked by your firewall to prevent access bypassing your reverse proxy
+    # Alternatively, uncomment the lines below and comment `network_mode: "host"` above to specify port mappings.
+#    ports:
+#      - "127.0.0.1:7880:7880/tcp"
+#      - "7881:7881/tcp"
+#      - "50100-50200:50100-50200/udp"
+```
+
+Next, we need to configure LiveKit. In the same directory, create `livekit.yaml` with the following content - remembering to replace `LK_MATRIX_KEY` and `LK_MATRIX_SECRET` with the values you generated:
+
+```yaml
+port: 7880
+bind_addresses:
+  - ""
+rtc:
+  tcp_port: 7881
+  port_range_start: 50100
+  port_range_end: 50200
+  use_external_ip: true
+  enable_loopback_candidate: false
+keys:
+  LK_MATRIX_KEY: LK_MATRIX_SECRET
+```
+
+#### Firewall hints
+
+You will need to allow ports `7881/tcp` and `50100:50200/udp` through your firewall. If you use UFW, the commands are: `ufw allow 7881/tcp` and `ufw allow 50100:50200/udp`.
+
+### 3. Telling clients where to find LiveKit
+
+To tell clients where to find LiveKit, you need to add the address of your `lk-jwt-service` to your client .well-known file. To do so, in the config section `global.well-known`, add (or modify) the option `rtc_focus_server_urls`.
+
+The variable should be a list of servers serving as MatrixRTC endpoints to serve in the well-known file to the client.
+
+```toml
+rtc_focus_server_urls = [
+    { type = "livekit", livekit_service_url = "https://livekit.example.com" },
+]
+```
+
+Remember to replace the URL with the address you are deploying your instance of lk-jwt-service to.
+
+#### Serving .well-known manually
+
+If you don't let Continuwuity serve your `.well-known` files, you need to add the following lines to your `.well-known/matrix/client` file, remembering to replace the URL with your own `lk-jwt-service` deployment:
+
+```json
+  "org.matrix.msc4143.rtc_foci": [
+    {
+      "type": "livekit",
+      "livekit_service_url": "https://livekit.example.com"
+    }
+  ]
+```
+
+The final file should look something like this:
+
+```json
+{
+  "m.homeserver": {
+    "base_url":"https://matrix.example.com"
+  },
+  "org.matrix.msc4143.rtc_foci": [
+    {
+      "type": "livekit",
+      "livekit_service_url": "https://livekit.example.com"
+    }
+  ]
+}
+```
+
+### 4. Configure your Reverse Proxy
+
+Reverse proxies can be configured in many different ways - so we can't provide a step by step for this.
+
+By default, all routes should be forwarded to Livekit with the exception of the following path prefixes, which should be forwarded to the JWT/Authentication service:
+
+- `/sfu/get`
+- `/healthz`
+- `/get_token`
+
+<details>
+    <summary>Example caddy config</summary>
+    ```
+    matrix-rtc.example.com {
+
+        # for lk-jwt-service
+        @lk-jwt-service path /sfu/get* /healthz* /get_token*
+        route @lk-jwt-service {
+            reverse_proxy 127.0.0.1:8080
+        }
+
+        # for livekit
+        reverse_proxy 127.0.0.1:7880
+    }
+    ```
+</details>
+
+<details>
+    <summary>Example traefik router</summary>
+    ```
+    # on LiveKit itself
+    traefik.http.routers.livekit.rule=Host(`livekit.example.com`)
+    # on the JWT service
+    traefik.http.routers.livekit-jwt.rule=Host(`livekit.example.com`) && (PathPrefix(`/sfu/get`) || PathPrefix(`/healthz`) || PathPrefix(`/get_token`))
+    ```
+</details>
+
+
+### 6. Start Everything
+
+Start up the services using your usual method - for example `docker compose up -d`.
+
+## Additional Configuration
+
+### TURN Integration
+
+If you've already set up coturn, there may be a port clash between the two services. To fix this, make sure the `min-port` and `max-port` for coturn so it doesn't overlap with LiveKit's range:
+
+```ini
+min-port=50201
+max-port=65535
+```
+
+To improve LiveKit's reliability, you can configure it to use your coturn server.
+
+Generate a long random secret for LiveKit, and add it to your coturn config under the `static-auth-secret` option. You can add as many secrets as you want - so set a different one for each thing using your TURN server.
+
+Then configure livekit, making sure to replace `COTURN_SECRET`:
+
+```yaml
+# livekit.yaml
+rtc:
+  turn_servers:
+    - host: coturn.ellis.link
+      port: 3478
+      protocol: tcp
+      secret: "COTURN_SECRET"
+    - host: coturn.ellis.link
+      port: 5349
+      protocol: tls # Only if you've set up TLS in your coturn
+      secret: "COTURN_SECRET"
+    - host: coturn.ellis.link
+      port: 3478
+      protocol: udp
+      secret: "COTURN_SECRET"
+```
+
+## LiveKit's built in TURN server
+
+Livekit includes a built in TURN server which can be used in place of an external option. This TURN server will only work with Livekit, so you can't use it for legacy Matrix calling - or anything else.
+
+If you don't want to set up a separate TURN server, you can enable this with the following changes:
+
+```yaml
+### add this to livekit.yaml ###
+turn:
+  enabled: true
+  udp_port: 3478
+  relay_range_start: 50300
+  relay_range_end: 50400
+  domain: matrix-rtc.example.com
+```
+
+```yaml
+### Add these to docker-compose ###
+- "3478:3478/udp"
+- "50300-50400:50300-50400/udp"
+```

+# Setting up TURN/STUN
+
+[TURN](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT) and [STUN](https://en.wikipedia.org/wiki/STUN) are used as a component in many calling systems. Matrix uses them directly for legacy calls and indirectly for MatrixRTC via Livekit.
+
+Continuwuity recommends using [Coturn](https://github.com/coturn/coturn) as your TURN/STUN server, which is available as a Docker image or a distro package.
+
+## Installing Coturn
+
+### Configuration
+
+Create a configuration file called `coturn.conf` containing:
+
+```ini
+use-auth-secret
+static-auth-secret=<a secret key>
+realm=<your server domain>
+```
+
+:::tip Generating a secure secret
+A common way to generate a suitable alphanumeric secret key is by using:
+```bash
+pwgen -s 64 1
+```
+:::
+
+#### Port Configuration
+
+By default, coturn uses the following ports:
+- `3478` (UDP/TCP): Standard TURN/STUN port
+- `5349` (UDP/TCP): TURN/STUN over TLS
+- `49152-65535` (UDP): Media relay ports
+
+If you're also running LiveKit, you'll need to avoid port conflicts. Configure non-overlapping port ranges:
+
+```ini
+# In coturn.conf
+min-port=50201
+max-port=65535
+```
+
+This leaves ports `50100-50200` available for LiveKit's default configuration.
+
+### Running with Docker
+
+Run the [Coturn](https://hub.docker.com/r/coturn/coturn) image using:
+
+```bash
+docker run -d --network=host \
+  -v $(pwd)/coturn.conf:/etc/coturn/turnserver.conf \
+  coturn/coturn
+```
+
+### Running with Docker Compose
+
+Create a `docker-compose.yml` file and run `docker compose up -d`:
+
+```yaml
+version: '3'
+services:
+  turn:
+    container_name: coturn-server
+    image: docker.io/coturn/coturn
+    restart: unless-stopped
+    network_mode: "host"
+    volumes:
+      - ./coturn.conf:/etc/coturn/turnserver.conf
+```
+
+:::info Why host networking?
+Coturn uses host networking mode because it needs to bind to multiple ports and work with various network protocols. Using host networking is better for performance, and reduces configuration complexity. To understand alternative configuration options, visit [Coturn's Docker documentation](https://github.com/coturn/coturn/blob/master/docker/coturn/README.md).
+:::
+
+### Security Recommendations
+
+For security best practices, see Synapse's [Coturn documentation](https://element-hq.github.io/synapse/latest/turn-howto.html), which includes important firewall and access control recommendations.
+
+## Configuring Continuwuity
+
+Once your TURN server is running, configure Continuwuity to provide credentials to clients. Add the following to your Continuwuity configuration file:
+
+### Shared Secret Authentication (Recommended)
+
+This is the most secure method and generates time-limited credentials automatically:
+
+```toml
+# TURN URIs that clients should connect to
+turn_uris = [
+    "turn:coturn.example.com?transport=udp",
+    "turn:coturn.example.com?transport=tcp",
+    "turns:coturn.example.com?transport=udp",
+    "turns:coturn.example.com?transport=tcp"
+]
+
+# Shared secret for generating credentials (must match coturn's static-auth-secret)
+turn_secret = "<your coturn static-auth-secret>"
+
+# Optional: Read secret from a file instead (takes priority over turn_secret)
+# turn_secret_file = "/etc/continuwuity/.turn_secret"
+
+# TTL for generated credentials in seconds (default: 86400 = 24 hours)
+turn_ttl = 86400
+```
+
+:::tip Using TLS
+The `turns:` URI prefix instructs clients to connect to TURN over TLS, which is highly recommended for security. Make sure you've configured TLS in your coturn server first.
+:::
+
+### Static Credentials (Alternative)
+
+If you prefer static username/password credentials instead of shared secrets:
+
+```toml
+turn_uris = [
+    "turn:coturn.example.com?transport=udp",
+    "turn:coturn.example.com?transport=tcp"
+]
+
+turn_username = "your_username"
+turn_password = "your_password"
+```
+
+:::warning
+Static credentials are less secure than shared secrets because they don't expire and must be configured in coturn separately. It is strongly advised you use shared secret authentication.
+:::
+
+### Guest Access
+
+By default, TURN credentials require client authentication. To allow unauthenticated access:
+
+```toml
+turn_allow_guests = true
+```
+
+:::caution
+This is not recommended as it allows unauthenticated users to access your TURN server, potentially enabling abuse by bots. All major Matrix clients that support legacy calls *also* support authenticated TURN access.
+:::
+
+### Important Notes
+
+- Replace `coturn.example.com` with your actual TURN server domain (the `realm` from coturn.conf)
+- The `turn_secret` must match the `static-auth-secret` in your coturn configuration
+- Restart or reload Continuwuity after making configuration changes
+
+## Testing Your TURN Server
+
+### Testing Credentials
+
+Verify that Continuwuity is correctly serving TURN credentials to clients:
+
+```bash
+curl "https://matrix.example.com/_matrix/client/r0/voip/turnServer" \
+  -H "Authorization: Bearer <your_client_token>" | jq
+```
+
+You should receive a response like this:
+
+```json
+{
+  "username": "1752792167:@jade:example.com",
+  "password": "KjlDlawdPbU9mvP4bhdV/2c/h65=",
+  "uris": [
+    "turns:coturn.example.com?transport=udp",
+    "turns:coturn.example.com?transport=tcp",
+    "turn:coturn.example.com?transport=udp",
+    "turn:coturn.example.com?transport=tcp"
+  ],
+  "ttl": 86400
+}
+```
+
+:::note MSC4166 Compliance
+If no TURN URIs are configured (`turn_uris` is empty), Continuwuity will return a 404 Not Found response, as specified in MSC4166.
+:::
+
+### Testing Connectivity
+
+Use [Trickle ICE](https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/) to verify that the TURN credentials actually work:
+
+1. Copy the credentials from the response above
+2. Paste them into the Trickle ICE testing tool
+3. Click "Gather candidates"
+4. Look for successful `relay` candidates in the results
+
+If you see relay candidates, your TURN server is working correctly!
+
+## Troubleshooting
+
+### Clients can't connect to TURN server
+
+- Verify firewall rules allow the necessary ports (3478, 5349, and your media port range)
+- Check that DNS resolves correctly for your TURN domain
+- Ensure your `turn_secret` matches coturn's `static-auth-secret`
+- Test with Trickle ICE to isolate the issue
+
+### Port conflicts with LiveKit
+
+- Make sure coturn's `min-port` starts above LiveKit's `port_range_end` (default: 50200)
+- Or adjust LiveKit's port range to avoid coturn's default range
+
+### 404 when calling turnServer endpoint
+
+- Verify that `turn_uris` is not empty in your Continuwuity config
+- This behavior is correct per MSC4166 if no TURN URIs are configured
+
+### Credentials expire too quickly
+
+- Adjust the `turn_ttl` value in your Continuwuity configuration
+- Default is 86400 seconds (24 hours)

+# Partnered Homeserver Operator Requirements
+> _So you want to be an officially sanctioned public Continuwuity homeserver operator?_
+
+Thank you for your interest in the project! There's a few things we need from you first to make sure your homeserver meets our quality standards and that you are prepared to handle the additional workload introduced by operating a public chat service.
+
+## Stuff you must have
+if you don't do these things we will tell you to go away
+
+- Your homeserver must be running an up-to-date version of Continuwuity
+- You must have a CAPTCHA, external registration system, or apply-to-join system that provides one-time-use invite codes (we do not accept fully open nor static token registration)
+- Your homeserver must have support details listed in [`/.well-known/matrix/support`](https://spec.matrix.org/v1.17/client-server-api/#getwell-knownmatrixsupport)
+- Your rules and guidelines must align with [the project's own code of conduct](guidelines).
+- You must be reasonably responsive (i.e. don't leave us hanging for a week if we alert you to an issue on your server)
+- Your homeserver's community rooms (if any) must be protected by a moderation bot subscribed to policy lists like the Community Moderation Effort (you can get one from https://asgard.chat if you don't want to run your own)
+
+## Stuff we encourage you to have
+not strictly required but we will consider your request more strongly if you have it
+
+- You should have automated moderation tooling that can automatically suspend abusive users on your homeserver who are added to policy lists
+- You should have multiple server administrators (increased bus factor)
+- You should have a terms of service and privacy policy prominently available
+
+## Stuff you get
+
+- Prominent listing in our README!
+- A gold star sticker
+- Access to a low noise room for more direct communication with maintainers and collaboration with fellow operators
+- Read-only access to the continuwuity internal ban list
+- Early notice of upcoming releases
+
+## Sound good?
+To get started, ping a team member in [our main chatroom](https://matrix.to/#/#continuwuity:continuwuity.org) and ask to be added to the list.

-# Setting up TURN/STURN
-
-In order to make or receive calls, a TURN server is required. Continuwuity suggests
-using [Coturn](https://github.com/coturn/coturn) for this purpose, which is also
-available as a Docker image.
-
-### Configuration
-
-Create a configuration file called `coturn.conf` containing:
-
-```
-use-auth-secret
-static-auth-secret=<a secret key>
-realm=<your server domain>
-```
-
-A common way to generate a suitable alphanumeric secret key is by using `pwgen
--s 64 1`.
-
-These same values need to be set in Continuwuity. See the [example
-config](./reference/config.mdx) in the TURN section for configuring these and
-restart Continuwuity after.
-
-`turn_secret` or a path to `turn_secret_file` must have a value of your
-coturn `static-auth-secret`, or use `turn_username` and `turn_password`
-if using legacy username:password TURN authentication (not preferred).
-
-`turn_uris` must be the list of TURN URIs you would like to send to the client.
-Typically you will just replace the example domain `example.turn.uri` with the
-`realm` you set from the example config.
-
-If you are using TURN over TLS, you can replace `turn:` with `turns:` in the
-`turn_uris` config option to instruct clients to attempt to connect to
-TURN over TLS. This is highly recommended.
-
-If you need unauthenticated access to the TURN URIs, or some clients may be
-having trouble, you can enable `turn_guest_access` in Continuwuity which disables
-authentication for the TURN URI endpoint `/_matrix/client/v3/voip/turnServer`
-
-### Run
-
-Run the [Coturn](https://hub.docker.com/r/coturn/coturn) image using
-
-```bash
-docker run -d --network=host -v
-$(pwd)/coturn.conf:/etc/coturn/turnserver.conf coturn/coturn
-```
-
-or docker-compose. For the latter, paste the following section into a file
-called `docker-compose.yml` and run `docker compose up -d` in the same
-directory.
-
-```yml
-version: 3
-services:
-    turn:
-      container_name: coturn-server
-      image: docker.io/coturn/coturn
-      restart: unless-stopped
-      network_mode: "host"
-      volumes:
-        - ./coturn.conf:/etc/coturn/turnserver.conf
-```
-
-To understand why the host networking mode is used and explore alternative
-configuration options, please visit [Coturn's Docker
-documentation](https://github.com/coturn/coturn/blob/master/docker/coturn/README.md).
-
-For security recommendations see Synapse's [Coturn
-documentation](https://element-hq.github.io/synapse/latest/turn-howto.html).
-
-### Testing
-
-To make sure turn credentials are being correctly served to clients, you can manually make a HTTP request to the turnServer endpoint.
-
-`curl "https://<matrix.example.com>/_matrix/client/r0/voip/turnServer" -H 'Authorization: Bearer <your_client_token>' | jq`
-
-You should get a response like this:
