Description:
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.

Not packaged, so too early to request a backport.

[Will Uther (willu-mailinglists)]

It seems that some packages are available here:

http://ppa.launchpad.net/pbxbuntu-drivers/ubuntu hardy main

(which I found here: http://wiki.freeswitch.org/wiki/Quick_Start )

I haven't tried it myself yet, but thought it worth pointing out.

[Will Uther (willu-mailinglists)]

Hi,
  Just leaving notes here for whoever follows. FreeSwitch 1.0.2 will not compile with libtool 2 (which is used in intrepid and jaunty). There are some patches being worked on here:

http://jira.freeswitch.org/browse/FSBUILD-82

to fix that. They apply cleanly to the source of the package I noted above (which is 1.0.2 with some patches).

With that patch, the source builds, but the deb package has a few problems on jaunty.

[Ian Justman (ianj)]

Attempted a build under Jaunty using the latest (1.0.3 from upstream) tarball's bundled debian/ directory. Once deps were installed, the package built cleanly and installed without any issues. Will now have to test to make sure the program actually works.
