What I like most about 3CX is that it truly functions as a digital phone. It's very easy to use—once I open the app, I don't have to keep logging into web pages repeatedly. If I need to go somewhere, I can simply take my laptop with me and stay connected through 3CX, as long as I have a stable internet connection.
