This is an even more egregious violation of someone’s attention than IM.
We tried to use mumble on one team with push-to-talk and it only lasted a few hours.

If I can receive a message, respond to it four hours or a day later, and receive a phone call for anything more urgent than that, I'm happy to use IM platforms for collaboration.
Additionally the social protocols are different. An email requires (some level of) planning and completeness. An IM can include just one question without reams of context, or it can involve a long detailed back-and-forth.
Questions over IM can be resolved in minutes or hours. Questions over email somehow morph into hideous monstrosities that waste days without anyone being satisfied with the answers.
And of course your mileage may vary, different organizations are different, etc...
Isn't that exactly Slack with the "Do not disturb" mode on does or email?
