[VoiceOps] Matter of quality

[J. Oquendo]

For those on this list who'd be willing to share particularly from say
an ITSP (Carrier) side, off-list, on-list, etc., what are the 
percentages for quality, system issues some of you are using for
baselines/metrics. For example, I have one or two (alright maybe 10-20
at max) common 's:whiner:clients:g' who have caught management's ear.
"My call to a cellular dropped after 120 minutes!@" From my POV, I have
two maybe three common clients who are complaining... "Dropped call,
call sounded garbled, etc., etc., etc" From my perspective, even if I
had 1,000 of these calls in a day, it's less than .5% of the amount of
calls I process. Nevertheless, we as engineers want to perform due
diligence versus blurting the ever popular "told you so." This means
tracking down all other carriers' issues (Comcast filtering anyone), any
potential outages, and so on (you all know the routine).

So long story (rambling) short, what are some of the gauges you guys
(big boys not onesies twosies) use to measure quality metrics (amount of
dropped calls versus successful calls, ARS ratios, MOS, etc). I use a
combo of Acmes, NCites and soon to be Transnexus in the mix. Also, what
pro-grade measurement tools are recommended, less I waste an hour @
CAIDA or similar. Requirements of tools in mind: MOS would be nice,
tracing calls would be nice, storing SIP sessions would be cool. High
volume traffic parsing (think 100s of gigs here) Making coffee, even
cooler! (Beggars can't be choosy). For the vendors on the list selling
tools, please don't solicit, I'd rather hear what peers have to say
rather than spend time on the phone away from the beauty of figuring out
why someone else's configuration/setup doesn't work.
