# Force-unbind an AOR (or a single contact within it)

`DELETE /sip/registrations/{aor}`

The AOR must be URL-encoded in the path (for example, `sip:alice@vb.example` is encoded as `sip%3Aalice%40vb.example`). Without query parameters, every Contact under the AOR is removed; with `?contact=<contact-uri>` only that single Contact is removed.

## Response `204`

Binding(s) removed

## Other responses

- `400` — Invalid AOR encoding
- `404` — AOR (or specified contact) not found

## Changes

- **2026-06-02** `f2079fd29bcd` — 1 info
  - endpoint added
