20 The World's First Cross-Platform Scalable FREE Multi-Protocol Soft Switch
22 FreeSWITCH is a scalable open source cross-platform telephony platform designed to route and
23 interconnect popular communication protocols using audio, video, text or any other form of media.
24 It was created in 2006 to fill the void left by proprietary commercial solutions. FreeSWITCH also
25 provides a stable telephony platform on which many telephony applications can be developed using
26 a wide range of free tools.
28 FreeSWITCH was originally designed and implemented by Anthony Minessale with the help of Brian West
29 and Michael Jerris. All 3 are former developers of the popular Asterisk open source PBX. The project
30 was initiated to focus on several design goals including modularity, cross-platform support,
31 scalability and stability. Today, many more developers and users contribute to the project on a daily
34 We support various communication technologies such as Skype, SIP, H.323 and GoogleTalk making it easy
35 to interface with other open source PBX systems such as sipXecs, Call Weaver, Bayonne, YATE or
38 FreeSWITCH supports many advanced SIP features such as presence/BLF/SLA as well as TCP TLS and sRTP.
39 It also can be used as a transparent proxy with and without media in the path to act as a SBC
40 (session border controller) and proxy T.38 and other end to end protocols.
42 FreeSWITCH supports both wide and narrow band codecs making it an ideal solution to bridge legacy
43 devices to the future. The voice channels and the conference bridge module all can operate at 8, 12,
44 16, 24, 32 or 48 kilohertz and can bridge channels of different rates. The G.729 codec is also
45 available under a commercial license.
47 FreeSWITCH builds natively and runs standalone on several operating systems including Windows,
48 Mac OS X, Linux, BSD and Solaris on both 32 and 64 bit platforms.
50 FreeSWITCH supports FAX, both over audio and T.38, and can gateway between the two.
52 Our developers are heavily involved in open source and have donated code and other resources to other
53 telephony projects including openSER, sipXecs, The Asterisk Open Source PBX and Call Weaver.
