I'm pretty sure no landlines from decades ago come even close to a decently configured voice chat server using e.g. Opus.

- ghaff 10y agoWhich, even stipulating that is the case, is not what most people use. Instead many phone conversations involve "Wait, are you still there" "Can you hear me?" [Shouted] "What?" No, we've most assuredly given up universal quality for convenience and lower prices. We CAN provide high quality but we mostly don't want to make the tradeoffs to do so.
- toast0 10y agoOpus has lot of variables, but if you could get 53k connections consistently with a modem, you were probably getting quality slightly under G.711 (because of robbed-bit signaling and any analog line noise). PCM encoding has a lot less latency than Opus, and circuit switching means essentially zero jitter. If you don't mind adding some latency, and can control jitter, Opus can handle wider bandwidth audio, and is much more bitrate efficient.
