# What does the VARTA error `trunk_not_found` mean?

The `trunk_id` you supplied doesn't match a trunk registered for your tenant.


**HTTP status:** `404`  ·  **Type:** `invalid_request_error`

## What it means

The `trunk_id` you supplied doesn't match a trunk registered for your tenant.

## What causes it

Raised by the trunk read/delete endpoints and the dial-time trunk loader (`backend/app/api/v1/telephony.py`), the latter reached from `POST /v1/calls` when `dial: true`.

## What to do

Register the trunk with `POST /v1/trunks` first, or check `trunk_id` against the list returned by `GET /v1/trunks`.
