# About This Guide

The Administrator Guide covers the functionality and configuration of your Cloud Voice hosted phone system (a cloud-based PBX, or Private Branch Exchange, the system that routes calls for your organization). It walks you through everyday operation and ongoing maintenance.

## Who this guide is for

These pages are written for the administrators who deploy and manage Cloud Voice. They assume you are comfortable with networking and general IT administration.

:::tip
Setting up a brand-new system? Work through the list roughly top to bottom. Start with the **Status Center** to check system health, then move on to extensions, trunks, and call handling.
