# Transfer Active Call

> Transfer an in-progress call to a different phone number.

## Overview

Transfers an active call to a different phone number while the call is in progress. The current call leg is replaced with a `<Dial>` to the new number, no announcement is played to either party.

Only calls in `queue_status: "started"` are eligible. Once transferred, the call record's `transferred_to` field is updated so the new number appears in call details.

***

## Headers

## Body Parameters

**call\_id** `string` *required*

ID of the active call to transfer. Must currently be in progress.

**transfer\_number** `string` *required*

Destination phone number in [E.164](https://en.wikipedia.org/wiki/E.164) format (for example `+12223334444`). Parsed against the US region by default, so 10-digit US numbers also work.
