Introduction

FreeSWITCH supports many features that are typically associated with a telephone system or Private Branch Exchange (PBX). The recipes in this chapter focus on a number of functions that are widely used in PBX systems such as voicemail, faxing, call recording, IVR menus, and more.

Note

Historically, the term PBX refers to a specific type of telephone system. However, it is now commonly used as a general term for any type of telephone system.
