# Delete a SIP trunk

`DELETE /v1/voice/trunks/{trunk_id}`

Removes the SIP trunk. Calls already in progress on this trunk are not affected. After deletion, new calls cannot use the trunk. Historical leg records retain the trunk reference. The generated domain is not reused.

## Code samples

**TypeScript**

```ts
await bird.voice.trunks.delete("trunk-id");
```
