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.

SureVoIP, a UK ITSP based in Scotland and FreeSWITCH
Suretec recently got approval from Ofcom, the U.K. communications regulator, to assign U.K. telephone numbers. Therefore, SureVoIP can assign phone numbers across the United Kingdom and Northern Ireland. The company is also authorised to supply global numbers for over 60 countries.
This is unique in the Scottish market, because other companies act as "middle-men" between clients and service providers.
SureVoIP is partnering with British Telecom (BT) through a VoIP Interconnect to offer clients added benefits. SureVoIP has also partnered with Xconnect on their Global Alliance program, as well as two other U.K. VoIP carriers.
SureVoIP also provides 24/7 emergency telephone support.
Gavin Henry, managing director of SureVoIP, and founding member of the Suretec Group, said, "Our journey to securing the approval from Ofcom has been long and complex, involving the submission of detailed business plans, demonstrating an in-depth knowledge of the Communications Act 2003, various legal requirements, help from ITSPA (we've worked so hard that we will soon be getting the ITSPA Quality Mark), documentation and a significant investment in equipment throughout the U.K. With out FreeSWITCH and the FreeSWITCH community this would not have been possible."
"Our position as an Ofcom regulated service provider will make us a preferred supplier, as we are ideally placed to offer a holistic and competitive service to clients within the North-east of Scotland and beyond," Henry said. "The applications of VoIP technology are clear and we see it being of particular interest to the oil and gas, shipping, legal and financial industries as they need to make international, reliable and cost effective communications as a basic function."
"FreeSWITCH has been instrumental in passing interoperability testing with all carriers and especially BT. It's scales so well that our hardware usage is kept to the minimum needed to power our reliable and fault tolerant core platform. We also use FreeSWITCH and FusionPBX to power our hosted platforms, oh and let's not forget OpenSIPS and PostgreSQL."
"We're all about Open Source software and it's no secret that millions of customers and consumers worldwide benefit from projects like FreeSWITCH, even if they don't know it. The community behind FreeSWITCH is always so responsive. The IRC channel is brilliant, the mailing list is brilliant as is the commercial support available from the project team, which is also second to none. It's actually quite hard to fault the project at all", says Gavin Henry.
Established in Scotland in 2003, the Suretec Group specializes in open source IT support and consultancy, open source telecoms and training in open source software. SureVoIP is the fourth division within the group, which also includes Suretec Systems, Suretec Telecoms and Suretec Training.
