Asterisk Opensource vs. Aterisk business Edition

What is the difference?
I’m just curious. I think Asterisk is awesome though, and I’d like to start playing around with it.

ABE isn’t bleeding edge like AOS is. I sell ABE to my clients because of the support and the fact that I feel Digium deserves to get paid for the wonderful work that is being done. I run AOS in my office because I like to see the latest greatest and if it breaks I can fix it.

The company line is that ABE is stable while AOS might not be. Yes, clients of mine have found bugs in ABE but so far Digium is working on getting them fixed for us. I will continue to have my clients buy support just because of that.
