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 current stable release of Freeswitch is 1.2.1, released on 14-August-2012. Older releases and other files are here, along with digital signatures you can use to verify your download. Installation instructions are here; they favor retrieving the current source code from our git repository, and that's generally a safe approach to take as well.
The stable 1.2 series is available in Git branch v1.2.stable (changelog). 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.
If you wish you have an even newer experimental version you can use the Master branch (changelog) from Git. New features will only be added to the Master branch. This will have the newest, latest & greatest features, but due to upgrading of the bundled libraries it may 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.
Any previous 1.0 release (eg 1.0.4, 1.0.6) is now ancient and will contain a range of resolved bugs, and you should seriously consider upgrading to 1.2.

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.
