Standard RTCP loss counters (fraction lost, cumulative lost) count packets that never arrived, while packets that arrive too late for the jitter buffer are reported separately as discards in RTCP XR. A call can therefore sound choppy while basic RTCP shows little loss, and heavy jitter should be checked in that case.
