Basically, when you buy from UReach, the underlying technology is very different. I don't know what UReach runs for sure, but they're what we call BlackBox infrastructures. You have no idea what keeps this company up and running, and given that UReach's CTO is a former Director for the Members of Technical Staff at AT&T, and since UReach has been around forever, it's probably safe to say that they're not running FreeSWITCH as their core (More likely big iron hardware; which is antithetical to a SaaS service like this).

Profig will have a faster feature iteration time period because they're a smaller company, whereas it's much harder for UReach to dev new features. Also Profig has the added advantage of having a small core market: hosted PBX. They aren't (at least at this time) targeting providers; something UReach is doing actively.

TL;DR: Profig runs on a great core, and they don't have 10+ years of embedded stuff to work through so their pace of feature iteration will be higher.

Does that help answer the Question?
