I like that it is easy for me as an IT person who has limited technical knowledge to use this service because of its ease-of-use features. This software also allows you to manage your phone system from anywhere in the world via internet which is great! There are not any downsides so far about my experience with this product. It's pretty much perfect but if there were something i disliked then maybe it would be better. We have solved our problem of having employees being able to call each other without having to worry about expensive long distance charges or losing minutes by placing calls outside of their area codes.
