Class CallStats

This object carry various statistic informations regarding the quality of an audio or video stream for a given Linphone.Call.

To receive these informations periodically and as soon as they are computed, implement the call_stats_updated() callback inside a Linphone.CoreListener. At any time, the application can access latest computed statistics using Linphone.Call.AudioStats and Linphone.Call.VideoStats.
