Installs in a flash. Very professionally done!

I checked out the website and burnt a cd. It works! and its free. Hell they've even got a flash movie that runs you through the setup. We don't have a web based fax server so we're going to set it up for this first.. and we'll be moving our phone system over. I just don't understand how other vendors like cisco, nortel, avaya etc are going to make any money. Confused...
