We continue improving Zingaya to provide with the best possible sound quality. New version of the widget uses special bandwidth check feature that helps to detect the audio codec which will be used for the call and check if call is possible with currently available bandwidth and ping. If detected bandwidth or ping isn’t good enough for a good call quality system will notify about that and will ask to call again later [when network connection is good enough].
We are working on another few updates for significant increase in speed and performance of our website and widget in Europe and Russia. Stay tuned!
