## Signature

```typescript theme={null}
await client.startCall();
```

## Parameters

## Returns

`Promise<void>`

## Throws

An error if the client isn't connected (`'Client not connected. Call connect() first.'`), the SIP client isn't registered, or the call fails to start.

## Example

```typescript theme={null}
await client.connect();
await client.startCall();
console.log('Call started');
```

### With Error Handling

```typescript theme={null}
try {
  await client.connect();
  await client.startCall();
} catch (error) {
  console.error('Failed to start call:', error.message);
}
```
