Incredible PBX™ for Asterisk-GUI provides virtually the same feature set of applications for Asterisk as our previous releases. But this time around, you get a Gotcha-Free PBX with pure and honest open source GPL code. No patent, trademark, or copyright minefields to trip you up. Just abide by the clear GPL licensing terms and copy, embellish, and redistribute to your heart’s content. Incredible PBX for Asterisk-GUI is truly a lean, mean implementation designed to be frugal with memory and extremely versatile in terms of configuration.
