## List application lines

`GET /v1/telephony-lines`

Returns the list of external lines added by the application via `POST /v1/telephony-lines`. The list is returned in full — filtering, sorting, and `offset` are not supported; select the line you need on the client side.

## Parameters

| Parameter | Type | Default | Description |
|----------|-----|-----------|---------|
| `select` (query) | string | — | Field selection in camelCase: `?select=number,name` |
| `limit` (query) | number | `50` | Number of records (up to 5000) |

## Known specifics

**Only this application's lines.** The list contains lines created via `POST /v1/telephony-lines` under the current API key. Lines rented from Voximplant or connected over SIP are available via [`GET /v1/voximplant-lines`](./voximplant.md).

**Filtering, sorting, and `offset` do not work.** The `filter`, `order`, and `offset` parameters are accepted without error but ignored — the whole list of lines is returned. Only `limit` (caps the count) and `select` (field selection in camelCase) work. Filter by number or name on the client side.

**All response fields are in camelCase**, including `crmAutoCreate` (boolean). Previously this field came back in UPPER_SNAKE_CASE as the string `"Y"`/`"N"` — since 07.2026 it is normalized to a camelCase boolean, like the other fields.

**`serverName` is not returned.** The field is declared in `GET /v1/telephony-lines/fields` but never comes back in the list under any condition — even if it was set at creation ([details](./create.md#known-specifics)).
