But you don't get zoom links via _SMS_ do you?

Almost all links I get via SMS are phishing. The rest is OTP, there is sometimes a link in the same SMS but I _never_ clicked a link in an SMS...

My point is, the inhibition to click a link inside an SMS is very high with lots of users, hence I can't imagine this working well.

Also, it's purely inconvenient. You're not having a conf call at a previously agreed time, you want to call someone, this means it's spontaneous or somewhat urgent...

Most people lead up to an invitation to a video call with text messages (e.g. "When are you free for a video call?") unless they're very familiar with the other party.
