Hi, Basically pjmedia clock is controlled by sound device clock (or master clock if you use null sound device). Sound device/master clock interval is implisitly set by combination of its attributes, i.e: samples per frame, channel count and clock rate. For example: samples per frame = 160 channel count = 1 clock rate = 16000 the interval will be: (160 / 1 / 16000) * 1000 = 10 ms Please note that some sound devices may have clock drift, so the interval is not exactly 10 ms, and even sometimes there is burst e.g: clocked 5 times sequentially in a very short period then the next clock comes after about 5*10 ms.
