Technical Tip
Question –
How to get the best voice quality?
Answer – 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, G.722.1 codec on
broadband, on dialup try the G.729, iLBC, or other codecs;
For more information, read
the FAQ.
