Admin voice
A voice region is a named group of media machines, and a voice server is one machine registered inside it. Together they are the topology Voice places a session into when it joins a voice channel or a call.
No operation here addresses a live session, a participant, or a track. Get voice state counts reports occupancy, and List RTC regions is the caller-facing view of the same regions.
Media transport
Section titled “Media transport”LiveKit is the media transport. Each voice server record names one LiveKit deployment and the API key pair the instance authenticates to it with.
endpoint is that deployment’s signalling URL, a ws:// or wss:// address. Fluxer hands it to the placed session verbatim as the endpoint of Voice Server Update, and the client opens its media connection there. The API rewrites the same value to http:// or https:// for its own room service calls, and it keeps any path prefix.
api_key and api_secret mint the access token the placed session presents. The token is valid for 600 seconds, grants room admission to exactly one room, and has the track sources the member’s permissions allow.
A room is one voice channel. A guild channel uses the room name guild_{guild_id}_channel_{channel_id} and a private call uses dm_channel_{channel_id}.
A participant is one voice connection, identified as user_{user_id}_{connection_id}. One account holding several connections in a channel is several participants. Going live publishes a screen share track from the participant that already exists, so a stream needs no second server, room, or grant.
Placement eligibility
Section titled “Placement eligibility”Four stored fields decide whether a region or a server can be chosen for one placement. Fluxer evaluates the four identically on both records, and it also skips a server whenever is_active is false. It resolves a region first and then a server inside it, so a caller admitted to a region whose servers all refuse it has no access to that region.
allowed_user_ids is evaluated first and on its own. A non-empty list admits only the accounts it names and refuses every other caller whatever the remaining three fields say. An empty list gates nothing.
vip_only, required_guild_features, and allowed_guild_ids are guild gates. When none of the three is set, the record admits every caller that passed the user gate, including a private call, which has no guild. When any of the three is set, the record admits only a placement that has a guild, so a restricted region or server is never selectable for a call or a group direct message.
With a guild present, a guild named by allowed_guild_ids is admitted at once and the other two gates are not consulted. Otherwise vip_only requires the guild to hold the VIP_VOICE guild feature, and required_guild_features requires the guild to hold at least one of the features it names. A guild holding none of them is refused.
Admin voice region object
Section titled “Admin voice region object”A region record has the identity a client sees, the coordinate placement measures distance from, and the eligibility fields described under placement eligibility. It has no capacity, no health, and no server count.
The operator supplies id on creation, and it is the primary key. It is the value a channel stores as its rtc_region and the value Modify call region accepts, so changing it means creating a new region and deleting the old one.
Structure
Section titled “Structure”| Field | Type | Description |
|---|---|---|
| id | string | The ID of the region, chosen by the operator and never renamed (1-64 characters) |
| name | string | The name shown for the region in a client (1-100 characters) |
| emoji | string | The emoji the operator configured for the region (1-64 characters) |
| latitude | number | The latitude placement measures distance from, in decimal degrees |
| longitude | number | The longitude placement measures distance from, in decimal degrees |
| is_default1 | boolean | Whether automatic placement falls back to this region |
| vip_only2 | boolean | Whether the guild has to hold VIP_VOICE |
| required_guild_features2 | array[string] | Guild features that admit a guild, any one of which suffices (max 100) |
| allowed_guild_ids23 | array[snowflake] | The guilds admitted without consulting the other two guild gates (max 1000) |
| allowed_user_ids3 | array[snowflake] | The accounts allowed to use the region at all (max 1000) |
| created_at | ?ISO8601 timestamp | Time the region record was created, or null when the stored row has none |
| updated_at | ?ISO8601 timestamp | Time the region record last changed, or null when the stored row has none |
| servers?4 | array[Admin voice server object] | The servers registered in the region |
1 The flag is not exclusive, and setting it on a second region does not clear it on the first. Each node then treats the first region its reload enumerates as the default, and a topology with the flag on no region falls back the same way
2 Setting any of these three makes the region unusable for a private call
3 Duplicate entries collapse and the returned order is not the submitted order
4 Present only on List voice regions and Get voice region, and only when include_servers resolved to true. List voice regions sorts the array by server identifier, and Get voice region returns it in the order the store yields
Example
Section titled “Example”{ "id": "europe-north", "name": "Northern Europe", "emoji": "🇸🇪", "latitude": 59.33, "longitude": 18.06, "is_default": true, "vip_only": false, "required_guild_features": [], "allowed_guild_ids": [], "allowed_user_ids": [], "created_at": "2026-02-11T08:14:00.000Z", "updated_at": "2026-08-02T17:45:31.000Z"}Admin voice server object
Section titled “Admin voice server object”A server record names one LiveKit deployment, the API key pair the instance authenticates to it with, and its own copy of the eligibility fields. A server is reachable for placement only when its region is also reachable.
The region_id and server_id pair addresses one server, and a server belongs to exactly one region. The same server identifier can exist in two regions, and moving a server between regions means deleting it and recreating it. Both are operator-chosen strings of 1 to 64 characters, and no operation renames either one.
A server can have its own coordinate. When it does, placement measures distance from that coordinate to pick the closest server for an automatically placed session. When it does not, the server takes no part in distance comparison.
Structure
Section titled “Structure”| Field | Type | Description |
|---|---|---|
| region_id | string | The ID of the region the server belongs to (1-64 characters) |
| server_id | string | The ID of the server, unique inside its region (1-64 characters) |
| endpoint1 | string | The LiveKit signalling URL the client opens its media connection to |
| latitude2 | ?number | The latitude replacing this server’s region coordinate, in decimal degrees, or null when the region coordinate is used |
| longitude2 | ?number | The longitude replacing this server’s region coordinate, in decimal degrees, or null when the region coordinate is used |
| is_active3 | boolean | Whether the server is in rotation for new placement |
| vip_only | boolean | Whether the guild has to hold VIP_VOICE |
| required_guild_features | array[string] | Guild features that admit a guild, any one of which suffices (max 100) |
| allowed_guild_ids4 | array[snowflake] | The guilds admitted without consulting the other two guild gates (max 1000) |
| allowed_user_ids4 | array[snowflake] | The accounts allowed to use the server at all (max 1000) |
| created_at | ?ISO8601 timestamp | Time the server record was created, or null when the stored row has none |
| updated_at | ?ISO8601 timestamp | Time the server record last changed, or null when the stored row has none |
1 An instance can configure an internal URL that the API uses for its own room service calls to one designated server, and that URL changes neither the stored value nor the value the session receives
2 The two coordinates are set and cleared together, and a server with only one of them cannot be stored
3 Fluxer skips an inactive server when it resolves a new placement. Server-side moderation of a session already on it keeps working
4 Duplicate entries collapse and the returned order is not the submitted order
Example
Section titled “Example”{ "region_id": "europe-north", "server_id": "europe-north-server-1", "endpoint": "wss://voice.example.com/livekit", "latitude": null, "longitude": null, "is_active": true, "vip_only": false, "required_guild_features": [], "allowed_guild_ids": [], "allowed_user_ids": [], "created_at": "2026-02-11T08:15:22.000Z", "updated_at": "2026-02-11T08:15:22.000Z"}List voice regions

1 An omitted credential is left unchanged and a supplied one replaces it. An empty string fails the length bound, so a credential can be replaced but never cleared
2 The two coordinates are supplied together and are either both null or both a number. Sending both as null clears the override and returns the server to its region coordinate
3 A supplied collection replaces the stored collection outright, so removing one entry means sending the complete remaining set and clearing a collection means sending an empty array

Section titled “Side effects”The write sets updated_at to the time it ran, and each node reloads its topology and uses the stored credentials for later calls to the server. Setting is_active to false stops new placement and does not move sessions already on the server.
One Admin audit entry with the action update_voice_server and the target type voice_server records the region identifier and the server identifier in metadata, together with the audit reason. The entry records neither credential and no field diff, so a credential rotation is indistinguishable in the audit log from any other update.
