I have been testing AxVoice for nearly a month now. I works, but sound could be better for other party. Some complain of "breaking up" sounds. It could be my setup on my asterisk and not AxVoice.
I would like to test with other AxVoice beta users to see if type of connection makes a difference.
I am not happy with their voice quality either. Same "breaking up" sounds. Out of all previous providers ( voip.net, acanac.com), this is the worst one.
I think of canceling at the end of the first month.
