I have avoided phone calls for years, to the extent possible. Especially for one-to-one communication. They are a combination of low-fidelity (no video so no facial cues, often poor quality sound) and intrusive (a ‘foreground’ activity that makes it hard or impossible to multitask). So, as much as possible, I’ve steered people toward consumer video tools like Skype or Hangouts (high fidelity X foreground), or chat tools like Messages or Slack (low fidelity, background).
