Allow me to interject.

We were experiencing bug 218762 in our application back in November 2020. It seemed to have been resolved, and we didn't hear of it from users for a few months.

Now it is back. The attachment 426698 from Jeremy sounds exactly like bug 218762 sounded back in 2020. So I would say that whatever the fix for bug 218762 was, it just alleviated the symptoms, but the underlying issue remained, and now it just resurfaced after some code was change somewhere else.

While this does not affect the captured audio (aka audio sent from an iPhone to all other participant) directly, it does sometimes get picked up by the microphone (when headphones are not being used), and echo/noise cancellation algorithms have a hard time isolating and removing the static from the stream, so the stuttering makes its way to all participants of the call.
