From FreeSWITCH Wiki
Welcome to the community documentation wiki for FreeSwitch, a telephony construction kit for building everything from softphones to full Class 5 switches. You can embed Freeswitch into a soft- (or hard-) phone or OpenWRT router, hook it to PRI circuits through FreeTDM and hardware interfaces such as the Sangoma A100 line, or use it to build an office PBX phone system -- from scratch, or using packaged add-ons like FusionPBX.

FreeSwitch has a large and active development community, mailing lists and an IRC channel, an annual convention, and more. It's licensed under the MPL; the Mozilla Public License.
Which version should I use?
The stable 1.2 series is recommended for use. This is available in Git but also as a tarball. Although the tarball has the latest official stable release, there may be more recent patches to the stable branch in the v1.2.stable Git branch, therefore Git is still the recommended option.
The stable 1.2 series is available in Git branch v1.2.stable. Patches to the 1.2 series will be made here and periodically released as the next 1.2.x version. Since not every patch will mean a newer version you will get the very latest patches to the stable series by using this branch. This branch is a moving target - the checkout date and revision will form part of the version number.
The current stable release in a tarball of FreeSWITCH is 1.2.8, released on 02-April-2013. Older releases and other files are in the archive, along with digital signatures that you can use to verify your download.
If you wish to try an even newer experimental version you can use the Master branch from Git. New features will only be added to the Master branch. This will have the newest, latest, and greatest features, but due to upgrading of the bundled libraries it might be less stable than v1.2.stable for a short while. If you use this branch you should test the installation before allowing users to use it to confirm it is stable. You can then use 'git checkout' to install the same tested revision on all your systems.
NOTE that this is a formal change of development practice; Master used to be the recommended deployment target for all users, and now the tarballs and the Git stable branch serve that purpose. Older documentation/tutorials may still exist recommending using Git, but these will now be out-of-date.
Any previous 1.0 release (eg 1.0.4, 1.0.6) is now ancient and will contain a range of bugs that have since been resolved in newer releases, so you should seriously consider upgrading to 1.2 stable.
When upgrading please review the Release Notes page to see whether there are any behaviour changes since previous versions.
See the Download & Installation Guide.

What Is FreeSWITCH™?
| FreeSWITCH™ is an open source communications platform written in C from the ground up. Licensed under the MPL 1.1 and running natively on Windows, Mac OS X, Linux, *BSD, and other Unix flavors, potential users are given many choices on how and where to run the software.
With a desire to not reinvent the wheel, we've designed FreeSWITCH to take advantage of as many existing software libraries as possible. It has a modular, extensible architecture, with only limited and necessary functionality in its core. Optional modules can be employed to add virtually any functionality desired by the user.
