You can’t rely on your broadband provider or your VoIP company to tell you — they don’t know. The only way to find out if your connection has what it takes is to put it to the test.

Java-based testing of your "VoIP connection quality" that is run by Brix Networks, a company that sells testing and monitoring tools for VoIP systems.
