Hi Geoffrey,

you probably do this already, but i've found the ASR rate (200 OK - failures) 
which we generate from our accounting a really helpful value to quickly notice 
a QoS problem for a certain carrier. Especially if you can compare against 
past data, like the last day, or last week. If you then add NER (200 Ok - 
"carrier failures") it gives you an even better picture.

You probably should be able to build something like this also with the htable 
approach Daniel suggested and some web graph tool.

Cheers,

Henning
