There are plenty of terrific Asterisk-based commercial solutions available. We've already identified at least five! When you pull back the covers, that's exactly where the FreePBX Distro fits. It's not open source. It's not GPL. Scott trumpets its awesomeness, but that's because Scott makes a living selling it... as a commercial PBX. It turns out that the way other vendors have been treated, FreePBX (the GUI) wasn't much different... without litigation. Can Sangoma fix that? Sure they can IF they want to. But they've been extremely quiet since Jan. 1. That tells me they'd prefer to let this blow over and stick with business as usual. One has to wonder whether Sangoma did its due diligence homework. They certainly didn't speak with us. And remember, the same guys still are in the driver's seat doing things much the same way as best we can tell. The financial incentive package that's part of the Sangoma deal suggests that's unlikely to change anytime soon.
Let me suggest that we take a deep breath and patiently explore what else is available. Then let's objectively weigh the pro's and con's of the alternatives. We also haven't (yet) heard from Digium, and that may include some surprises as well. Will we find the perfect open source, (true) GPL GUI product? Who knows. We sure don't have one with FreePBX unless you want to hire a bunch of lawyers.
I can tell you that the number of available options is staggering, and some of the products are truly amazing. Many of those we've spoken with are interested! Whether we can reach a deal that everyone is comfortable with remains to be seen, but I am optimistic. I also think this process is long overdue given the manner in which some folks have been treated.
