A web phone is a browser-based phone interface that runs without installing anything. Simply navigate the the website, login, and make calls through any supported browser. It is independent of any platform, is ready to set up quickly, and , because it runs in the browser, is always secure and up to date through automatic updates and centralized security management. This does, however, mean that browser updates and security settings will effect your web phone use. You also have more limited configurations and customizations. If your internet connection is weak, you may experience a drop in reliability and performance from time to time.
