Now that's combining the worst of all worlds - now I need to speak (which is inconvenient by itself) to mute phone, thinking of proper speech in advance, and it also takes more time than typing. And I don't get "instant" response benefit of a phone call. No ability to send any data longer than few characters (no links, no data sets). Disruptive in the office. And if it was sent via anything non-phone then it is highly possible that quality would be garbage.
