Interesting thank you for the writeup! I tried to find a comparison of sound latency for old phones, modern mobile and e.g. MS Teams, but couldn't find any. I didn't know there were echo cancellation in old time phones: https://en.m.wikipedia.org/wiki/Echo_suppression_and_cancellation https://en.m.wikipedia.org/wiki/Echo_suppression_and_cancell... Is it maybe the background noise filters that mess up sound latency in Teams? I used to play with friends over a privately hosted Ventrilo server back in the days, and the conversations were always crystal clear and felt like instant. Maybe the VOIP providers just timeshare calls too much in their servers or have bad routing of packages.
