Do you use a Voice over IP (VoIP) provider such as Skype or Vonage to make long-distance phone calls to your friends, family, or colleagues? If you do, you might want to test your Internet connection's ability to handle this type of traffic.
TestYourVoIP.com will load a Java VoIP client and make a call from your computer to one of their Brix's U.S. or international test location and report the results back to you. This is a free service.
Note: This site requires that Java be installed on your local computer to perform the test.
