# registered

> The registered event fires when the SIP client successfully registers with the server.

Emitted when the SIP client successfully registers with the SIP server. After this event is emitted, the client is ready to make calls using [`startCall()`](https://docs-classic.cognigy.com/click-to-call/sdk/api-reference/start-call). Endpoints that don't require SIP registration never emit this event.

## Category

Connection

## Callback Parameters

None.

## Example

```typescript theme={null}
client.on('registered', () => {
  console.log('SIP client registered — ready to make calls');
});
```
