I'd say that any restaurant or salon that treats a customer booking a table or an appointment as 'unsolicited' might not stay in business for very long.
Robo-booking being used by people who simple put an entry in their own diary - the robot doing the booking and interaction. The human potential client has used minimal resources and because of the ease of use and lack of interaction will not perceive a cost in the making of the booking. I anticipate they'll change, cancel, noshow at a far higher rate than in-person bookers.
Bookings made might then both block other customers and potentially increase the cost to the supplier of administrating the booking [particularly with a micro-business where the supplier end is an actual person].
This, in contrast, is automated deal-making, targeting phone calls at businesses that want to close a deal. The context is entirely different.
Of course malicious behaviour will not comply, but would at least filter the mainstream products.
That's literally the reason they have phones.
