I've seen an increase in G722 calls and I've seen a few AMR-WB calls get through too for our International vendors. Its still relatively new for them outside of the IPX/VoLTE market. I've had a large PTT ask to help with end to end testing for AMR-WB with them. A handful of International vendors are supporting G722 with us but still only Inteliquent for domestic. Does Ribbon/Sonus charge extra for it even in passthrough modes preventing the rest of the domestic carriers from using it?
Rural Call Completion is definitely still a big quality issue. One way audio, foreign country ringback tone, and PDD followed by a 503 is what we test and try to mitigate before customers notice. The race to the bottom pricing has drawbacks. There are several CLECs that I won't put their "Gold" , "highest level" deck in route because its still garbage. Occasionally we will see dropped calls due to incorrectly configured SIP timers. I'm curious to see what happens with quality KPIs when more end destinations start validating/rejecting SHAKEN/STIR calls. Will we get higher PDD because carriers don't deploy their certs in a CDN and someone DDOSes the certificate host? Will end destination carriers finally start rejected the grey route International traffic with nothing or C level attestations?
