I love being able to be in my office but still have access to all of my calls with clients, customers etc without having to pick up my phone or walk over there! This is also great for when you are at home because it allows me to make sure everything goes smoothly if something does go wrong during the day while I am working remotely. None really - just works well! It's super easy to use so anyone can get involved right away. We were looking for an alternative communication system to our current one which was not as effective or user friendly. The benefits we've noticed since switching include improved productivity, better customer service and overall increased employee morale.
