FreeSWITCH
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 media gateway or a media server to host IVR
applications using simple scripts or XML to control the
callflow.
The software supports 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 also support both wide and narrow band codecs
making it a 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.
It is capable of being embedded into other projects, as well
as being used as a stand-alone application.
