AAPT certainly were running SS7 over various SDH technologies when I was last working on their call centre platform a few years back.

With Telstra, it's an EXTRAORDINARLY big deal. You still have to > use specific hardware, and SS7 signaling over ISDN Oh. My bad. I was basing my assumptions on how I've seen voice delivered in the US. Even big ol' bad boy and recalcitrant Telco, AT&T provides SIP over a PNI. At my $DayJob we have a 10G PNI to them. Easily provisioned and managed as just-another-IP-network. I was also under the impression, tho I could be wrong, that voice interconnects in the US are increasingly over private IP networks with SIP. I assumed Australia was doing the same. You are clearly saying "not so". But ISDN? I still have nightmares over Telstra-variant LAPD state-machines from the dark ages. I thought all that stuff was archaeological by now. Next thing you'll be telling me is that Telstra still carry voice over an ATM transport or some archaic plesiochronous network.
