I've installed one Allworx and it seems to just fine. Of course, it's a basic system with no special apps other than 1 remote phone. I used to work on Altigen systems a few years ago and hated them. I'm not sure how much they may have improved on them since. As for Toshiba and Comdial, I have no exposure.
Why Voip? Are you networking 2 or more sites? Do you want remote phones. What bells and whistles are you looking for that have you interested in Voip.
