# Merge Calls into an Audio Conference Call

If you are handling more than one call at once in the Cloud Voice App, you can bring the parties together into a single audio conference instead of switching back and forth between them. Once the calls are combined, you become the conference host and can manage the session from the call panel.

:::note
The result is always a 3-way conference: you plus two other participants. Even when you have several calls active, you merge one selected call together with your current call, so the conference tops out at three people including yourself.

## Before you begin

Your desktop client must meet a minimum version:

- **Windows**: version 1.7.3 or later
- **Mac**: version 1.7.3 or later

You also need to have the following in place:

- The Cloud Voice App is running in **Desktop Client** mode. The **Merge Calls** control is only available in this mode.

- At least two active calls of the same type are in progress.

:::caution
Only calls of the same type can be joined into a conference. You can merge two voice calls together, or two video calls together, but you cannot mix a voice call and a video call. The **Merge Calls** action will not combine calls of different types.

## Merge the calls

1. At the bottom of the call panel, click **Merge Calls**.

2. Choose how the calls are merged:

   - With exactly two active calls, click **Confirm** in the window that appears.

   - With more than two active calls, select the one call you want to bring in, then click **Confirm**.

## Result

The selected calls join into a single 3-way audio conference, with you as the host.
