I like how easy it has been to setup since all of our phone lines are in one place now! It's also very secure which my parents have told me they love about this software as well.
There really isn't much else you could ask from an app/software these days so we're satisfied therefor far enough at least for us right know. We've used other unified communications apps before but none were nearly perfect compared to unytalk thus far (yet). Our employees can be more productive while having their hands free by using voice commands through our phones instead of typing out emails.
