Still, I think his point is the weakest link still the PSTN hop, no 
matter where it will happen.
If you had only VOIP end-to-end, G.722 would be good, but in any step 
going via PSTN (the PRI idea only solve one side of the PSTN 
call..unless you have the PRI in both ends of the call with G.722 ?)
As people move forward into VOIP and peering, G.722 (and others) will 
come into play I guess, meanwhile, only for interoffice VOIP calls I guess ?
