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.
FreeSWITCH was originally designed and implemented by Anthony Minessale with the help of Brian West and Michael Jerris. All 3 are former developers of the popular Asterisk open source PBX. The project was initiated to focus on several design goals including modularity, cross-platform support, scalability and stability. Today, many more developers and users contribute to the project on a daily basis.
We support various communication technologies such as Skype, SIP, H.323 and GoogleTalk making it easy to interface with other open source PBX systems such as sipXecs, Call Weaver, Bayonne, YATE or Asterisk.
FreeSWITCH supports many advanced SIP features such as presence/BLF/SLA as well as TCP TLS and sRTP. It also can be used as a transparent proxy with and without media in the path to act as a SBC (session border controller) and proxy T.38 and other end to end protocols.
FreeSWITCH supports both wide and narrow band codecs making it an ideal solution to bridge legacy devices to the future. The voice channels and the conference bridge module all can operate at 8, 12, 16, 24, 32 or 48 kilohertz and can bridge channels of different rates. The G.729 codec is also available under a commercial license.
FreeSWITCH builds natively and runs standalone on several operating systems including Windows, Max OS X, Linux, BSD and Solaris on both 32 and 64 bit platforms.
FreeSWITCH supports FAX, both over audio and T.38, and can gateway between the two.
Our developers are heavily involved in open source and have donated code and other resources to other telephony projects including openSER, sipXecs, The Asterisk Open Source PBX and Call Weaver.

I must confess that I had never heard of Genesys Labs until I read this blog post today. In any case, the author of the blog post has some nice things to say about FreeSWITCH, although I was more interested in his thoughts on setting up secure VoIP. His comments on setting up TLS and dealing with the challenges of certificates and CA's was pretty insightful. If you are thinking about doing TLS and/or SRTP then definitely check out this blog post - it is a good read.
Over at Astricon this story came out: someone got NAILED for $400K in fraudulent toll charges. Ouch, indeed! Remember the mantra: lock down your VoIP systems!
Note: OnSIP was a silver sponsor at ClueCon 2011. They are great folks and we're glad to have them in the FreeSWITCH community!
This story comes from David Rowe, VoIP hacker extraordinaire. This is a reminder that even the best of us can make mistakes and otherwise forget to plug holes that we already know about. I recommend you read up on his experience. It shows that a combination of factors - in this case a characteristically evil SIP ALG and a config file miscue - can conspire to make your system quite hackable.
Let's all be careful out there!
Our buddy Dan York has written a piece about Microsoft's assimilation acquisition of Skype. For better or for worse it is a done deal. I don't know about you but I must confess that I'm keeping my eye on this one. It could be great or it could be a train wreck. In either case I've got the popcorn ready...
We wanted to keep everyone informed of the schedule for upcoming FreeSWITCH training. Darren Schreiber, co-author of the FreeSWITCH book and CEO of the 2600hz project, is the lead instructor. There are beginner and advanced classes as well as a 5-day complete training. Visit VoIP.com for all the details. Also, don't forget that Darren and Company can also offer customized training suited to your specific business and technical needs. Contact them at firstname.lastname@example.org to obtain more information.
Thanks to Darren and all the great folks at 2600hz for helping to expand the reach of the FreeSWITCH community all over the world!
Those of you running Linux/Unix systems no doubt make use of the time zone database. Now it seems a foolish group of astrologers/software developers has actually sued the long-time maintainer of this database, among others. They claim that they have a copyright on the timezone data. All the selacious details are available in this Techdirt post. Keep your eyes open on this one, it should be interesting.
An interesting item just came across my desk. A post over at Boston Review talk's about Susan Landau's new book: Surveillance or Security?: The Risks Imposed by New Wiretapping Technologies. It is quite an interesting read. If you are at all interested in Internet security and privacy, especially with VoIP communications, I highly recommend reading this article.
