I also miss reliable decent quality phone calls. I sometimes give up on Facetime/Whatsapp/Signal and switch to standard mobile call, or vice-versa, and I can hear that the calls through apps have much richer sound quality, when it's working. The voices are much less tinny, but the delays, echos and periods with just no connection, don't seem much better than standard mobile calls. And the delays and reliability of both is worse than analogue landline calls used to be.

I suppose that's to be expected moving to wireless tech, but local analogue landline calls used to be so fast that they had lower latency than a conversation across a room. I know we've gained a lot and I wouldn't trade VOIP for going back to only mobile, or giving up both to going back to landline, but it is a shame quality isn't higher.
