There seems to be a fair amount of Overlap - I see that Connect uses what I have used before as Nimbus (WLC) and it works well, but I am unfamiliar with the Zulu Cel Phone App - Which is better and why and which should I be selling/installing - Primarily we are looking at the Cel Phone App, but we do have some people wanting Web - is UCP still an option? Or has that been replaced by Zulu or Connect?
