A few months ago I began compiling a list of IP PBX products and other telephony platforms that are either directly Open Source, or are commercial products that have spawned from various open source projects. These include core open source platforms like Asterisk, Freeswitch and FreePBX, as well as commercial products developed and maintained by “for profit” companies.
I stopped counting at 101. It’s amazing to see the sheer range of choice out there for businesses and individuals seeking a VoIP communications solution. If you have developed or currently market a VoIP capable IP PBX product, and I neglected to mention you, please feel free to add your comments and I will put you on the list.
