Most of the support questions regarding voice calls are about sound
quality, absence of sound, and encryption. I focused on writing these
first (and will fill in the simple steps for making a call at a later date).

Please review the accuracy of my description of end-to-end encryption
(particularly the section labeled "Limits of end-to-end encryption"),
since I only have a cursory understanding of the concepts.
In the Troubleshooting section I could use some help with the
recommended bandwidth and interpreting the call info statistics (see the
"Poor Internet connection" bullet). Would this section also benefit from
recommended codecs for particular uses, or will that just confuse the
situation?
Could processing power of the computer or device be a factor in audio
quality, if a CPU intensive codec is used?
I wrote, "Windows Audio Session API (WASAPI)" is recommended for Windows
Vista or later. "Port Audio" is recommended for Linux. What is
recommended for Mac OS?
