# WebSocket registration

> Register SIP subscribers to Leamout over secure WebSocket.

Leamout exposes a secure WebSocket signaling endpoint for browser SIP clients. In the current development/acceptance topology it is published on TCP port `5062` and protected with TLS.

A browser SIP URI follows the subscriber identity:

```text theme={null}
sip:<username>@<sip-domain>
```

Configure your SIP client with the subscriber username/password and the WSS endpoint for your deployment.

<Warning>
  The development acceptance value `wss://127.0.0.1:5062` is not a production hostname. Production deployments must use their configured DNS name and valid TLS certificate.
</Warning>
