This page describes FreeSWITCH™ numbering conventions, basic download instructions, and directions to useful installation pages.


The FreeSWITCH™ numbering format is "version.release.maintenance".

Selecting a Version

The primary FreeSWITCH™ releases are:

Bugs or issues with the current public release must be tested using the latest Development release to determine if the problem is already fixed. Issues must be tested using Development before opening bug reports for them to be considered. If the bug persists in Development, then file an issue on GitHub: https://github.com/signalwire/freeswitch/issues

There are breaking changes between minor and major releases, so make sure to check the Release Notes before upgrading to avoid headaches.

If you're using version 1.8 which is tagged End Of Life, you should upgrade to 1.10 NOW.

Download Current Public Release

The latest maintenance level of the current public release of FreeSWITCH™ can be downloaded from freeswitch-files via a browser. For linux, it's easier to copy/paste the command line below. This single long line performs: 1- Determines the latest public release available. 2- Downloads the compressed source file. 3- Decompresses the file into a folder in the current directory. 4- Renames the folder to freeswitch. If you don't want the folder renamed, remove the last && to the end of the line.

FSfile=$(curl -s https://files.freeswitch.org/releases/freeswitch/ | grep -oE "freeswitch-[0-9]*\.[0-9]*\.[0-9]*\.-release\.tar\.bz2" | tail -n 1) && echo Downloading $FSfile && curl https://files.freeswitch.org/freeswitch-releases/$FSfile | tar -xj && mv ${FSfile/.tar.bz2//} freeswitch

Download Current Branch

Download the current branch using the -b argument followed by 'v' concatenated with the release number. The git command creates the freeswitch directory and downloads the FreeSWITCH™ source files, replace # with the release number. 

git clone –b v1.# https://github.com/signalwire/freeswitch.git

Download Development

Download the latest development release using the "git clone" command below which creates the freeswitch directory and downloads the FreeSWITCH™ development source files.

git clone https://github.com/signalwire/freeswitch.git

Installation Methods

The easiest way to get FreeSWITCH™ is to install a pre-built package for your operating system, available for some Linux distributions and Windows.

Debian 11 Package (FreeSWITCH 1.10)

Debian (preferred) The development team uses and builds against Debian. They recommend Debian because of its operationally stable, yet updated, kernel and wide library support. 

Centos 7 Package (FreeSWITCH  1.10)

CentOS 7 and RHEL 7


FreeSWITCH™ is available for source compilation on Unix , Linux, macOS, and Windows for the following reasons:

  • Pre-built binaries are not available
  • You want to see the entire process
  • You want to build the Development version because you require the very latest features or patches, or wish to hack FreeSWITCH

Debian 11 Bullseye Source

1.10 depends on a number of libraries included with Debian 11, which is the distribution of choice for FS core development team. Follow the instructions on the Debian page; refer to Debian Post-Install Tasks for finishing touches.


There is an installer and comprehensive macOS guide containing instructions for setting up FreeSwitch™ on a Mac with features such as autostart, emailing voicemails and log management.


Special notes for building from source on OpenBSD.

Updating Binaries

In version 1.4 the names of a number of configuration settings were changed, so you can not simply use old config files on your new binaries.

Settings of the form sip_*_media have become rtp_*_media because they properly control RTP media streams, SIP has nothing to do with them.

For example, sip_secure_media is now called rtp_secure_media
