# 3CX Phone Provisioning Configuration

## Introduction

This document provides instructions on configuring 3CX Phone Provisioning to interoperate with the ProSBC. Phone provisioning is used for automatic configurations of selected hardware SIP phones. Phone provisioning means:

* phone automatically connects to the PBX after booting and is assigned a phone extension,
* extensions are managed in the administration interface,
* if you confirm or plan it, the system will perform an automatic restart of provisioned phones if needed,
* phone firmware is automatically updated,
* displaying a company logo on hardware phones supported by 3CX Server
* accessing company contacts
