I use this software for my business to call customers, schedule appointments, receive email messages etc all from one place! It's very user friendly also it has an excellent customer support team that help me with any issues or problems i have using their product.
There are some minor features which could be improved such as having more options when scheduling meetings but overall its great! The best thing about this service/software is how easy they make things simple by putting everything in front of you so there is no need searching through files for something specific.
