# Delete SIP outbound trunk

> DELETE https://api.nabrah.ai/api/ext/sip-outbound/{sip_id}

Group: SIP outbound. Page: https://www.nabrah.ai/en/docs/api-reference/sip-outbound/delete-sip-outbound-trunk

Permanently deletes a single outbound SIP trunk from the project tied to your API key. After deletion, agents can no longer place outbound calls through this trunk. A successful request returns 204 No Content with no body. Authenticate with the `X-API-Key` header.

## Irreversible

Deletion cannot be undone. To restore outbound calling you must create a new trunk via POST /api/ext/sip-outbound.

## Authorization

- `X-API-Key` (string, header, required): your workspace API key.

## Path parameters

- `sip_id` (string, required): The unique identifier of the outbound SIP trunk to delete. Obtain it from the `id` field of GET /api/ext/sip-outbound (list) or GET /api/ext/sip-outbound/{sip_id} (single).
