Frequently Asked Questions

"Most of mobile computers have an embedded microphone and speaker. Make sure that your microphone is good enough by trying to record your speech. In order to get better audio quality and avoid echo, you may use headset, Blue Tooth, and wired headset etc; We strongly recommend you to install the latest version of operating system, sound and network drivers, and DirectX (check with dxdiag.exe, it should be 9.0 or higher). Check your Internet connectivity by pinging your party's IP address. A proper response time is below 100 ms unless the party you are calling is from Down Under. If the ping time seems too large, you Internet connection is too busy now. Try to stop any other activity. If the problem persists, ask your Internet provider or system administrator to fix it. For the best voice quality, use the G.711 codec on broadband, on dialup try the G729, iLBC, or other codecs."
