  3. Echoing

Why: Jitter is the average change in delay between successive packets. When packets arrive at different speeds, a speaker's voice sounds robotic. Microsoft flags average jitter above 30 ms as poor audio quality.

Huh, didn't know that: Microsoft says Teams can adapt to some jitter through buffering, and only notices once jitter exceeds the buffer.
