The company I work for here in NC sells their products exclusively, although about 80% is hosted. I'm not particularly impressed with what I've seen, but I spend most of my time supporting their base of customers with digital systems. When I participated in helping troubleshoot one of their hosted installations, I didn't see it as very sophisticated. Much like 1A2 with a few flexible keys. Everything is optional, meaning that adapters and other gadgets are required for basic functions such as music on hold or paging, but that's pretty much the case with a lot of IP systems. It seems like most of our customers that are choosing it are ones with dead systems who are in a pinch to get something up cheap and easy. Zultys offers their own hosting, and with a good dealer relationship, they are able to turn installations around the next day. The phones are a bit larger than I think they need to be, meaning and the styling is a bit basic, but they're solid and the speaker/handset audio quality is excellent.
