# Call Flip Overview

Call Flip hands an active call off from one device to another in mid-conversation. As long as the user's extension (their internal phone identity in the system) is registered, meaning signed in, on both devices, the call moves across without a pause or a dropped connection, so the person on the other end never notices the switch.

:::note
Call Flip only has somewhere to send a call when the same extension is registered on more than one device at the same time. If the extension is signed in on a single device, there is no second endpoint (device) to flip the call to.

## When you'd use it

Picture a sales rep taking a customer call at their desk who suddenly needs to head out of the office. Rather than ending the call and calling back, they flip it straight to their mobile phone and keep talking as they walk out the door.

## Ways to flip a call

Extension users have two ways to flip an in-progress call. Both reach the same result, so the right one to reach for depends on the device the user is holding.

:::tip
- Use the **Call Flip button** when the user is on the Cloud Voice App (mobile, desktop, or browser) and wants to pick the exact device to move the call to.
- Use the **Call Flip feature code** when the user is on a device without the app, such as a desk IP phone, because the code works from any endpoint.

### Use the Call Flip button

Clicking the **Call Flip** button shows the user every other device their extension is registered on. They pick the device they want, and the call moves there. No other devices ring, so the handoff is silent.

This method works from the Cloud Voice App on mobile, desktop, and in the browser, including when the browser client runs as a Google Chrome extension.

### Dial the Call Flip feature code

:::note
A feature code is a short dialable code (often one that starts with `*`) that triggers a built-in phone system function instead of placing a normal call.
:::

When a user dials the **Call Flip** feature code, every other device their extension is registered on rings at the same time. The user answers on whichever device they want, and the call is handed over to it.

Once the **Call Flip** feature code is turned on in Cloud Voice, this method is available from every endpoint, including plain desk phones that do not run the Cloud Voice App.

:::caution
The feature-code method only works after an administrator turns the **Call Flip** feature code on in Cloud Voice. While it is off, dialing the code does nothing.
