Not conflating mobiles with VOIP are you? Mobiles go from bad to
unuseable with excessive delay. Our VOIP has minimal delay (and I
suspect most of that is our interleaved ADSL), Bandwidth more than a
POTS line and no "donald duck" compression artifacts.

No bother here Dave, in fact call quality on 4G via Vodafone is very
good indeed..

... a tone dialer never works via a microphone any more.

I've not tried it, VOIP signals keypad presses outside the voice
channel for "press 1 for..." menu systems.

Until these companies do things so it sounds as good as a normal line
they can stuff it.

Our VOIP is better than a call carried over the POTS line used to
carry the VOIP... 3 ish miles of twisted pair takes it's toll on
analogue signals. Compared to VOIP a POTS call is lower level, lower
bandwidth, with some added noise/hum and sometimes dialing pulses.
