In my experience:
30/6 is always Tier 1 TDM
6/6 USA
60/60 Mexico
1/1 has always been grey routes that are great one day, and terrible the next.
Damn Lucent and their TNT's :)

We've been using Verizon to terminate to Russia. Their ASR's have been
HORRIBLE. They would regularly reject 50% or more of calls during peak times
with SIP server side final responses (500+). They informed us they don't offer
any sort of SLA's... pretty funny for a tier one carrier. How can you report
problems when there is no standard by which to measure quality? Qwest offer
SLA's, but it's so damn complicated, we are still trying to understand it.
Doug.
