possible to come up with something that had better sound quality than an
system designed 100 years ago.

The sound quality you get is highly dependent on available bandwidth, his
outging and your incoming. For example, when I have called home from London
the other person usually complained about sound quality when I used the
mobile data network but not when I used the hotel WiFi.

Yes it is. Home internet connections are a poor medium for real time voice and
video. Real time data needs a minimum fixed bandwidth. The POTS service with
its dedicated lines provides this.

Dedicated or prioritized (QoS) bandwidth for VoIP over DSL is no problem.
My DSL router is configured with a dedicated port for the VoIP adapter to
achieve this, together with some configuration on the DSLAM side.

POTS does not have sufficient bandwidth for video.

QoS won't help you if there is congestion at the exchange or anywhere along
the line.

While this is true, if you get a VoIP number from your internet provider,
the calls will not be routed over the regular Inernet, so this will not be
a problem. The point beeing that it's perfectly possible to provide the
same quality as POTS over IP.

Most office telephone systems are run over IP these days, indeed. Much
cheaper to install only one set of wiring.

Oh don't they just. If a bridge or router dies the phone system dies and
if you want to move a phone the bloody thing takes 2 minutes to reboot.
Its pathetic.

Which doesn't help if the congestion is between your exchange and your
Internet provider (on the BT wholesale backhaul, normally). Which is
where the congestion experienced by most domestic users in the UK
occurs, unfortunately.

It is, but only at some expense.
