# Manage Logged-in Cloud Voice App Clients for an Extension

As an administrator, you can see every Cloud Voice App client that is currently signed in to an extension, review the details of each associated device (device name, client type, and last login time), label a device with a remark, and sign the extension out of any device remotely.

:::note
Extension users can manage the devices signed in to their own Cloud Voice App as well. Any change they make is synchronized back to the PBX (Private Branch Exchange, the phone system that these extensions belong to), so the list you see in the web portal stays current.
:::

## Requirements

Before you begin, make sure both of the following are true:

- The Cloud Voice firmware is version **84.22.0.138** or later.
- At least one Cloud Voice App client is currently signed in to the extension.

:::tip
To confirm that an extension has an active client, check the **Online Status** column in the extension list. Go to **Extension and Trunk > Extension**, then read the **Online Status** column.

## Add a remark to a device

Give a device a label so it is easy to recognize in the list.

1. Log in to the Cloud Voice Dashboard at https://voice.izt.cloud and click **Login** to open your phone system's management portal with full administrator access, then go to **Extension and Trunk > Extension** and edit the extension you want to manage.
2. Open the **Cloud Voice App Clients** tab.
3. Scroll to the **Currently Logged-in Devices** section.

   This list shows each device signed in to the extension, together with its device name, client type, and last login time.

4. In the **Remark** column for the device, type your label.

5. Click **Save**.

The remark is synchronized to all of the extension's Cloud Voice App clients.

## Sign the extension out of a device

Remotely end an extension's session on a specific device.

:::caution
Signing a device out immediately ends the extension's session on that device. The person using it is logged out and sees an on-screen notice, and they will have to sign in again to use the app. Confirm you have the correct device before you continue.

1. Log in to the Cloud Voice Dashboard at https://voice.izt.cloud and click **Login** to open your phone system's management portal with full administrator access, then go to **Extension and Trunk > Extension** and edit the extension you want to manage.
2. Open the **Cloud Voice App Clients** tab.
3. Scroll to the **Currently Logged-in Devices** section.
4. Click ![Sign-out icon](/images/pbx/logout-circle.png) next to the device you want to sign out.

The extension is signed out of that device, and the message "This device has been logged out by you or the administrator" appears on the device's screen.
