I hate to say I told you so, but I told you so:
With almost 1 million VoIP connections tested through its Web site, Brix said that about 20 percent of all calls had unacceptable quality. This is up from about 15 percent of calls made about a year ago.
Let me make this as simple as possible: there are 1 billion people on the Internet today, and they each want more bandwidth. Unless bandwidth is continually added to the Internet, it slows down. VoIP is the first casualty of bandwidth congestion.
Net neutrality only makes this trend worse.
