# Node SDK — calls

> Node SDK reference for placing outbound voice calls programmatically with caller-ID checks and cap planning.

`CallsResource` is reachable on every Kataven Node client as `client.calls`. Each method maps to one HTTP endpoint on the [Hub API](/api-reference/introduction); links to the underlying spec entry are inline below.

Place outbound voice calls. The server enforces caller-ID ownership and per-tenant cost caps before dispatching to the carrier.

```typescript theme={null}
