I add this line in our in/out contexts:
exten => h,1,Noop(QOS=${RTPAUDIOQOS})

Then grep for 'QOS' in asterisk-verbose (assuming you have verbose logging on). I'm sure you could output it anwhere else as well with a system call/echo.

OK, how do you get such information -- at times it would be very useful
to know.

I’ve been dumping these to the verbose logs for some time and monitoring them, but I have not been able to determine why the numbers are so far off. I am more concerned with the packets lost due to priority queuing within our network.
