16641/188 = 8852% is not quite 8809% but I suspect it is just a
rounding issue. Of couse it makes no sense to lose more than 100%
but this is just a math formula. I don't think there are any checks
in the asterisk code to make sure the result of the math operation
makes sense.<br>

No you're reading it wrong.<br>

There are 188K received with no loss, and 16441K

This doesn't make any sense to me, either. There
can't be more packages<br>

running exactly the same time.<br>

Lost and Percent (pct) are not calculated by counting
packets. Those are calculated from the sequence
numbers in the RTP frame.<br>
<br>
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.<br>

There are 188K received and 188K transmitted. Pct is
unknown - what's Pct?<br>
<br>

Still 8809 does not sound like a percentage to me
😉 so there is something wrong with either the
label or the value.<br>
From what's in the code, you can see it's clearly
a lost Packet count not a percentage.<br>
So I guess Pct in this case is short for "Packet".<br>

Are you sure? I'm seeing here:<br>
<br>
...........Receive.........
.........Transmit..........<br>
Count Lost Pct Jitter Count Lost Pct
Jitter RTT....<br>
188K 0 0 0.000 188K 16641K 8809
0.000 0.026<br>
<br>
=> This doesn't sound reliable to me: there are
188K packets and 16641K of them are lost?! The Pct
value is fluctuating between about 6009 and 9009.<br>
<br>
Thanks,<br>
