> you have to dial the number

It must have been at least a decade since I actually dialled into a video conference using a phone, on any conferencing platform - I always connect audio via my laptop or phone, which I use with a Bluetooth headset.

I was actually having this conversation with a bunch of colleagues the other day, and every person in the call said the same thing, only difference was some used a USB headset, rather than Bluetooth.
