Those are calculated from the sequence numbers in the RTP frame. For example let's say you start the receiver (Asterisk) at Sequence #1....then something happens and it jumps to sequence #5000. The audio might be fine, but now the stats say 4998 packets were lost. Why is there a bizarre sequence jump? Hard to say. I have seen it because of bugs that eventually get fixed on the CPE, or even when there is a change of codec (or re-invite) mid-call. I would not worry too much about this unless you can reproduce it and can address it properly at the CPE level. A packet capture will clearly confirm what I am referring to here. Just look at every Sequence # in the RTP flow and you will see the jump.> >> ...........Receive......... .........Transmit.......... >> Count Lost Pct Jitter Count Lost Pct Jitter RTT.... >> 188K 0 0 0.000 188K 16641K 8809 0.000 0.026 > ^^^^ ^^^^ > There are 188K received and 188K transmitted.
