Calendly for Voicemail - does this exist? Should it?

Basically I hate being randomly interrupted by phone calls, but would be happy if people were able to schedule a meeting with me directly in the phone call.

Interaction would be something like:

1. Voicemail system says "Paul is heads down right now, press 1 to book a 30 minute meeting on Zoom, press 2 to leave a message"
2. If the caller hasn't signed up they would receive a text message with a web based sign up flow to link their calendar.
3. The VM system would compare the calendars and say "Does 2pm tomorrow work for you? Press 1 to accept Press 2 to find a later time".
4. The VM system would book the meeting with Zoom link.

Would anyone use this?

Thanks!
