From the same people who brought us Hotel Inn, we have a video conference call in real life:

Amusingly, despite having worked from home for over 10 years, I’ve never done a video call for work. It’s funny because in theory they should be superior, but I can count on a single hand the times I’ve been on a conference call at work and wished that we had video to go with the audio.

One tip I can give about conference calls over the phone for anyone new to them is to invest in a high quality set of headphones that puts sound into both ears. It was way easier to understand people when both ears are hearing the same thing and your brain can process what it hears in the way it’s used to. The quality is important, too, because if there is no distortion on the audio, it’s much easier to tell what people are saying. This applies not just to the fundamental frequency which their vocal cords are producing, but also to the higher frequencies produces by the mouth (called “formants”) which help to distinguish sounds like “ba” “ta” and “da” or “eh” and “ee”. A high quality speakerphone (which can do full duplex) will work, too. Cheap speakerphones are almost worse than nothing, though.
