Packet switched voice was such a mistake. Even under great conditions it is ROUTINELY worse than the worst days of circuit switched and TDM.

Kids these days will never know how great phones worked in the 80s and 90s. Fuck.

Give me that circuit switched reliability over high res audio with occasional/intermittent/unavoidable packet loss and jitter any day of the week.

The holiday bombing in Nashville provided clear evidence of what we've lost in terms of PSTN resiliency. I don't think there would have been region-wide loss of service for greater than 24 hours in say 1994.

Who cares about reliability, it is not as if lives depend on it. /s

If I look at the availability of phone service in my home (German metro area, cable) it is way below anyone would gave dared to provide in the TDM/ISDN times. I strongly believe only the redundancies people have with also having a mobile phone has allowed this to continue with lives being lost and regulators clamping down.

Are there statistics, or is this personal experience?

I've never had a landline phone fail, but I also haven't had one for about 12 years.

I have had a landline phone fail--a tree fell over on the next block down and took the wires along. Also, many years ago, I was in a building where we found the phones would work without power, but they wouldn't ring. While waiting to go home, we would resort to "polling"--pick up a line and see whether anyone was on it.

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.

[sneak]

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.

[walrus01]

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.
