# Phone System Overview

Your Cloud Voice PBX is a full-featured hosted phone system. From the PBX
management portal you can configure extensions and users, design call flows,
run inbound and outbound call center queues, and connect integrations such as
CRMs and Microsoft Teams.

Browse the full documentation set from the [Phone System guides](/pbx/guides/),
or use the sidebar and search to jump to a topic.

## What you can do

- **Extensions & users**: create extensions, set presence, voicemail, and
  call forwarding rules.
- **Call routing**: inbound routes, outbound rules, business hours,
  holidays, and caller ID handling.
- **Auto attendants & call flows**: build IVRs visually with the Call Flow
  Designer.
- **Call center**: inbound queues, agent consoles, wallboards, and the
  operator panel.
- **Devices**: auto-provision supported IP phones and manage firmware.
- **Integrations**: CRM, helpdesk, and productivity integrations.

## Where PBX management happens

PBX servers themselves are provisioned and linked from the
[Cloud Voice dashboard](/dashboard/phone-systems/); day-to-day PBX
administration (extensions, call flows, queues) happens in the PBX management
portal you reach from there.
