NOTE: A similar test that also provides JITTER results is described here. This is recommended as an additional step in determining if the JITTER on your ISP connection will affect VoIP service.
For either test:
•You can test with two codecs: G.711(high quality) and G.729(lower bandwidth)
•Ensure that your computer is wired directly to your Broadband connection (i.e. do not use a wireless connection at any point).
A wireless connection to the internet will not give a true result since your future VoIP gateway will be wired and enjoy unfettered broadband access. See Using the Gateway with a Wireless Access Point for a further discussion of wireless broadband issues.
•If you are connected to the Internet through a router, ports may be blocked, and the VoIPTest may fail. In this case, verify the results screen to validate if indeed the test failed because "There was a network problem talking to the server". You should rerun the test with complete access to the Internet (i.e. without a router).
•It is preferable to have Java installed on your computer for this test.
•Call Primus TBB Technical Support if you encounter any issues (test fails) or you have further questions.
Some browsers may experience difficulties with this test. For example, Firefox for the Macintosh does not seem to meet the correct Java requirements for this applet to run (although it appears that the latest version running under Tiger does have intermittent success). However, it seems to work fine on Safari without making any changes to the Mac OS Java settings.
