We have a team of 17 advisors that uses Nextiva and it has worked out exceptionally for us. I have used several other phone systems and Nextiva has by far had the least down time or problems where we cannot make/receive calls. It is also extremely easy to use. I also like the fact they are constantly trying to improve and you see new features or updates regularly which means to me they aren't satisfied with just good enough, they want to be better.
