Welcome To FreeSWITCH

The World's First Cross-Platform Scalable FREE Multi-Protocol Soft Switch


FreeSWITCH is a scalable open source cross-platform telephony platform designed to route and interconnect popular communication protocols using audio, video, text or any other form of media.  It was created in 2006 to fill the void left by proprietary commercial solutions. FreeSWITCH also provides a stable telephony platform on which many telephony applications can be developed using a wide range of free tools. More

FreeSWITCH Community,

After nearly 2 years of non-stop development, FreeSWITCH has evolved from an idea and an empty directory into a fully operational soft-switch capable of withstanding the loads 8-10 times as large as anything else they were able to deploy in the past with other software according to the reports from our early adopters.

I am happy to announce the immediate availability of FreeSWITCH 1.0 “Phoenix“ (Release Candidate 1). The Phoenix symbolizes the rebirth of a new era and I hope this new release will be the first step in a new age of voice-over-IP development we can all benefit from.

We anticipate the official FreeSWITCH 1.0 “Phoenix” release date to be Monday, May 26th 2008. We will have a formal release presentation at this year’s ClueCon 2008 August 5th-7th 2008. http://www.cluecon.com

I would like to thank our community for the testing, bug reporting, code contributions, feedback and financial donations that helped us get this far, especially those who were involved from day 1.

Please take this opportunity to test drive FreeSWITCH as we will be making it available as binary packages for the first time to practice for the official 1.0 release. The code and arrangement of the configuration will not change apart from bug fixes and tweaks from this point forward. As always, the code will still be available in svn at the usual place.

For download instructions please stay tuned to:

The packages will be online soon.

Thanks Everyone!

HD-Telephony: HIP or Hype?

Submitted by admin on Wed, 01/16/2008 - 20:03

Since the advent of the High Definition Television, The HD phenomena has spread far and wide in recent years making the “ordinary” “extraordinary” with the addition of a simple 2 letter prefix. The telecommunications industry is no exception with the strengthening concept of HD-Telephony. Is it all hype or is there an actual benefit to better sounding phone calls? How does this affect the hardware and software designed to keep us connected? As a software developer in this field, I hope to shed a little light on the topic and separate the facts from the misconceptions.

Release Candidate 1 on the way!

A few new features have been developed in the last few months.

We added:

* SRTP support: Make calls with secure RTP 

* mod_spidermonkey_curl: Now you can get and post http data from javascript.

* mod_dialplan_asterisk: A dialplan module similar to the asterisk dialplan syntax.

* mod_cdr_csv: A templated CSV CDR module.

* mod_tone_stream: Play tones anywhere a file can be played.

* USER channel, a way to call a user in the directory as a channel. 

* mod_voicemail: a full featured enterprise scale voicemail application tied to the core directory that can be used with a local sqlite database or shared across multiple boxes with ODBC. It supports mutiple greetings, fully customizable keys for every function, fully customizable email template, ability to forward messages to your email once you have listened to them, urgent messages with accurate urgent/non urgant message counts in mwi and templatable ivr prompts via the FreeSWITCH phrase macro interface.

*mod_limit: a small application to allow restriction of certian simotaneous resources in the dialplan which also works locally with sqlite and at an enterprise scale with ODBC.

A Few New Features

Submitted by admin on Tue, 10/02/2007 - 21:23

As we move another step closer to our 2nd beta, we added a few more features this week.

1) The channel variable RECORD_STEREO=true will make the record_session
application record a stereo file with the read and write streams in
seperate channels. For the more seasoned developer, this also means the
media bugs have a capability to return audio in mixed or stereo form
for other applications as well.

2) The addition of mod_fifo. This module makes it possible to park
many calls in a fifo queue and unpark them in the order in which they
were received. This will make it possible to make parking and call
distribution applications. The module sends events detailing stages of
callflow as well as an api interface command to generate a full report
of the call state. And is purely dynamic with no configuration necessary
to support an infinite amount of fifo queues.

Its been a long and hard road but we are finally at Beta1. Please download, test and report any bugs on Jira.

In addition I would like to point out that Cepstral sponsored work on OpenMRCP so the world could benefit from MRCP v1 and v2 integration for accessing ASR and TTS resources. FreeSWITCH and its team of great people were instrumental in making sure OpenMRCP became a reality.  Here is the news release from Cepstral about OpenMRCP.
