I notice that the slight latency over ordinary mobile voice calls does degrade the quality of conversations. People interrupt each other, or wait because they are worried about interrupting someone, more often than IRL convos.

Some carrier should make low-latency phone calls a competitive advantage. This is an easy thing to measure and quantify (i'd use average latency between two popular distant points, e.g. NY<->SF, plus 1 standard deviation) and so it's easy to advertise.
