UDP transport TURN client for datagram-based relay allocations. Uses a single UDP socket for both STUN signalling and Send/Data Indications. All [Client](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#client-3) methods apply; data is relayed via [sendData()](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#senddata) using Send Indications.

## Inherited from [`Client`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#client-3)

| Kind | Name | Description |
|------|------|-------------|
| `function` | [`Client`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#client-4)  |  |
| `function` | [`~Client`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#client-5) `virtual` |  |
| `function` | [`start`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#start-27) `virtual` | Connects the socket to the TURN server and starts the allocation sequence. Permissions must be added via [addPermission()](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#addpermission) before calling this. |
| `function` | [`stop`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#stop-16) `virtual` | Stops the timer, cancels pending transactions, and closes the socket. |
| `function` | [`sendAllocate`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#sendallocate) `virtual` | Sends an Allocate request to the server with the configured transport and lifetime. On first call the server will typically respond with a 401 challenge; the client re-sends with credentials automatically. |
| `function` | [`addPermission`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#addpermission) `virtual` | Adds multiple peer IP addresses to the permission list. |
| `function` | [`addPermission`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#addpermission-1) `virtual` `override` | Adds a single peer IP to the permission list, or refreshes it if already present. Permissions should be added before [start()](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#start-27); they may also be added later, in which case a new CreatePermission request is required. |
| `function` | [`sendCreatePermission`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#sendcreatepermission) `virtual` | Sends a CreatePermission request for all IPs currently in the permission list. Called automatically after allocation succeeds and periodically by the timer to refresh expiring permissions. |
| `function` | [`sendChannelBind`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#sendchannelbind) `virtual` | Channel bindings (RFC 5766 Section 11) are intentionally not implemented. They are a bandwidth optimization that replaces STUN-framed Send/Data indications with a compact 4-byte ChannelData header. This only benefits high-throughput media relay scenarios; in practice, media flows directly via ICE/DTLS rather than through this TURN client's data path, so the optimization is not worth the complexity (channel number allocation, 10-minute binding refresh timers, ChannelData wire framing). Data relay uses [sendData()](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#senddata) with Send Indications instead. |
| `function` | [`sendRefresh`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#sendrefresh) `virtual` | Sends a Refresh request to extend the allocation lifetime. Called automatically by the timer when roughly one-third of the lifetime remains. |
| `function` | [`sendData`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#senddata) `virtual` | Sends a Send Indication to relay `data` to `peerAddress` through the TURN server. If permissions are still being negotiated the indication is queued and flushed once CreatePermission succeeds. |
| `function` | [`handleResponse`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#handleresponse) `virtual` | Dispatches an incoming STUN/TURN response to the appropriate handler. |
| `function` | [`handleAllocateResponse`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#handleallocateresponse) `virtual` | Processes a successful Allocate response; extracts mapped/relayed addresses and advances the state to Authorizing, then sends CreatePermission. |
| `function` | [`handleAllocateErrorResponse`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#handleallocateerrorresponse) `virtual` | Handles an Allocate error response; manages the 401 challenge/re-send flow and sets the client to Failed for unrecoverable errors. |
| `function` | [`handleCreatePermissionResponse`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#handlecreatepermissionresponse) `virtual` | Handles a successful CreatePermission response; flushes queued Send Indications and advances state to Success. |
| `function` | [`handleCreatePermissionErrorResponse`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#handlecreatepermissionerrorresponse) `virtual` | Handles a failed CreatePermission response; clears all permissions and sets the client to Failed. |
| `function` | [`handleRefreshResponse`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#handlerefreshresponse) `virtual` | Handles a Refresh response; updates the stored lifetime. |
| `function` | [`handleDataIndication`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#handledataindication) `virtual` | Handles an incoming Data Indication; extracts peer address and data and forwards to [ClientObserver::onRelayDataReceived()](https://auscaster.com/icey/docs/api-reference/icy-turn-ClientObserver.md#onrelaydatareceived). |
| `function` | [`transportProtocol`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#transportprotocol) `virtual` |  |
| `function` | [`createTransaction`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#createtransaction) `virtual` | Creates a new STUN transaction, registers the progress callback, and adds it to the active transaction list. |
| `function` | [`authenticateRequest`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#authenticaterequest) `virtual` | Adds STUN long-term credential attributes (Username, Realm, Nonce, MessageIntegrity) to `request` if the realm has been received from the server. |
| `function` | [`sendAuthenticatedTransaction`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#sendauthenticatedtransaction) `virtual` | Calls [authenticateRequest()](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#authenticaterequest) then sends the transaction. |
| `function` | [`removeTransaction`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#removetransaction) `virtual` | Removes a transaction from the active list. The [IntrusivePtr](https://auscaster.com/icey/docs/api-reference/icy-IntrusivePtr.md#intrusiveptr) keeps the object alive until the caller's copy is released. |
| `function` | [`mappedAddress`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#mappedaddress) `const` |  |
| `function` | [`relayedAddress`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#relayedaddress) `virtual` `const` `override` |  |
| `function` | [`closed`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#closed-7) `const` |  |

| `function` | [`addPermission`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#addpermission-3) `virtual` | Adds a permission for `address`, or refreshes the existing one. The port is ignored; TURN permissions are IP-only. |
| `function` | [`hasPermission`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#haspermission) `virtual` | Checks whether a permission exists for `peerIP`. Local addresses (192.168.x.x and 127.x.x.x) are always permitted. |
| `function` | [`hasPermission`](https://auscaster.com/icey/docs/api-reference/icy-turn-Client.md#haspermission-1) `virtual` | Checks whether a permission exists for `peerAddress`. The port is ignored; TURN permissions are IP-only. |
