It can also be due to waveApi buffers that are larger than 20 ms, as a consequence several packets are delivered through the capture callback at the same time. Linphone does this also on windows. This must not be a problem thanks to jitter buffer. > Hello, > > I guess that this is caused by Windows timer which is not enough precise > to send packets each 20ms.
