FreeSWITCH | Communication Consolidation

FreeSWITCH is an open source telephony platform designed to facilitate the creation of voice and chat driven products scaling from a soft-phone up to a soft-switch. It can be used as a simple switching engine, a PBX, a media gateway or a media server to host IVR applications using simple scripts or XML to control the callflow.

We support various communication technologies such as SIP, H.323, IAX2 and GoogleTalk making it easy to interface with other open source PBX systems such as sipX, OpenPBX, 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, 16 or 32 kilohertz and can bridge channels of different rates.

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.

Our developers are heavily involved in open source and have donated code and other resources to other telephony projects including openSER, sipX, The Asterisk Open Source PBX and Call Weaver.

a Spec Sheet is available on our Wiki.

How does FreeSWITCH compare to Asterisk?

How does FreeSWITCH compare to Asterisk? Why did you start over with a new application? These are questions I’ve been hearing a lot lately so I decided to explain it for all of the telephony professionals and enthusiasts alike who are interested to know how the two applications compare and contrast to each other. I have a vast amount of experience with both applications with about 3 years of doing asterisk development under my belt and well, being the author of FreeSWITCH. First I will provide a little history and my experience with Asterisk, then I will try to explain the motivations and the different approach I took with FreeSWITCH.
