I don't use OpenVXI for reasons like - dead project, performance, reliability, non-scaling architecture, wrong dependencies - and so on. We have a target of 20,000 sessions on my laptop alone - and I have already secured that and more. We can do more, but we start running out of memory. What I expect out of FreeSWITCH/CCXML/VXML is that we can scale up as much as FreeSWITCH can without CCXML/VXML being the show-stopper. Then OpenVXI came out it was adopted by tier1 companies that still use the stack today. Some people consider that a reference, but they fail to understand that those companies have the strength needed to pick up half-done-work and make it right. Though the ones I know of still struggle with performance issues. <snip> So when it was first invented, people tried to sell the editors for money, the only implementation were commercial and there was no real acceptance to it. The first open source VXML stack was dependency-ridden and archaic to even build for many years. </snip>
