# Reboot the System from the Web Interface

You can restart your Cloud Voice PBX (Private Branch Exchange, the system that routes all of your phone calls) directly from the web portal, without needing console or command-line access. Use the steps below when maintenance or troubleshooting calls for a full system restart.

:::caution
A reboot ends every active call on the system. Confirm that no calls are in progress before you continue, otherwise those conversations will be dropped.
:::

:::tip
Plan reboots for a low-traffic window, such as after business hours. This limits how many users are affected by the short outage.
:::

## Reboot the PBX

1. Sign in to the PBX web portal and open **Maintenance > Reboot**.
2. Under **Reboot Now**, select **Reboot Now**.
3. When the confirmation dialog appears, choose **Yes** to start the restart.

## What to expect

The system typically comes back online in about a minute.

:::caution
While the PBX is restarting, phones cannot make or receive any calls, including emergency (911) calls. Make sure users have another way to reach emergency services during the reboot window.

If you have turned on notifications for the **System Reboot** event, Cloud Voice sends an alert to the configured contacts through their selected notification channels each time a reboot occurs.
