The program works and was fairly easy to setup so I would say that the project is off to a great start. Since the developers are gracious enough to provide the software for free, I think that the users such as myself should provide feedback, but only if there will always be a free version. I've never been interested in demoing the beta to find I have to pay for the good working version. The Proxy Hostname or IP won't accept domain names. Shouldn't be forced to use a STUN server unless necessary. I have had Axon running perfectly fine without it. The Line Status shows my external line being not registered but I can make and receive calls, so it's creating a false alarm.
