The Open sourced complete PBX, Asterisk has reached another milestone. Now the version 1.2.0 has been released. I am a long time user of this complete VOIP PBX purely in software, and have been impressed with it ever since I first got it. I even met Mark at a trade show a few years back and I even like the guy too, not only his software. On the trade floor he took time to walk me through the inner working of the System.
According to Mark Spencer and Kevin P. Fleming, this release of Asterisk contains over 3,000 improvements on version 1.0, including hundreds of new features and applications.

If you are interested you can download it from ftp.digium.com FTP servers, as well as the Digium CVS servers (under the ‘v1-2-0′ tag).

They also said that they want to extend Their thanks to all the community members whose contributions have made this release possible; without their coding, support, testing and other involvement Core developers would not have achieved this milestone!
