At this point, we are only using the phone service part of the system. We haven't started using the sales part of the system yet. But so far, we love it! Several things that have helped our office communication is the ability to put notes immediately after the phone call and that we can all see the notes for every client all day. Also, the ability to text our clients all within the same program. And, I like that when we call for help, a real person answers and helps you on the first call versus having to be passed around until you finally get to the department that can help you, like a lot of other phone companies. There are many many other features that we love. So glad we switched to DYL! I have already referred 2 other collegues because it has help us so much. Thank you!
