I set up a few pbxinaflash many years ago. It had autoprovisioning but was a pain in changes. Mitel is nice but pricey. My friend is looking around and knew I had some voip experience. I hadn't done anything with voip systems in awhile. I checked the pbxact hardware and it's not really impressive. My friend got a quote from them and it was the licensing that got him since freepbx is more about the feature.
