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.
