You need the ability to enter the code on a numeric keypad when dialing in from an office phone. Compatibility with "ancient" enterprise practices is also important.

Why not a word-based code for most people, and a numerical one for places that need them (can be enabled/disabled in the tenant), and only allows for phone connections?

Ah, that makes a lot of sense. I'd never considered that!
