Yeah, but also in an era of vastly less inter city capacity for long haul. Properly implemented Opus on a network with under 1% packet loss sounds great.
Yeah but how often are two people connected by networks that maintain <1% PL and low jitter for the entirety of a length of a call?
I'm thinking of just shipping 79xxs to my close friends and telling them to plug them directly into their routers, but even that will go to shit around 20:00 local as their residential networks overload.
The weakest link is absolutely the residential class last mile contended access networks. I've regularly seen 0.00% packet loss for weeks at a time on business class connections between two points in the continental US, but when one end is slightly flaky, all bets are off.
