Tim,
Is this the same system that was showing such lousey numbers for iLBC? Dave and I conferred on that and he thought there might be something wrong with that system or in that case the hardware floating point. As I remember on the surface from its specs one would not think that. Do you have any other hardware to do a comparison with? Some systems just don't work as well as others even though they are suppose to. I suspect you could run some benchmarks to see.

I think you might be comparing apples and oranges. A ping is icmp protocol at the ip level and over a set period of time while the Asterisk statistics are cumulative over the entire time it has been running. It shows loss of iax udp packets which can be expected. Unless the loss is excessive over time I would not worry about it. There is never any guarantee that a udp packet is going to make it to its destination. If it were really bad you would hear it in the audio. There is a way to actually ping tcp and udp connections but I have never done it. My connections show the same minor loss over extended periods of use. Are you actually having a problem?

Anyone know why regular ping would show no loss, yet IAX shows there is loss? I’ve even seen localhost connections with IAX loss. Which makes me think there is something other than a network problem.
Here’s an example… 0% loss ICMP ping yet 7% IAX loss:
