No, it just means there won't be a 'call' option when clients send you a booking request. If you select After you've booked a stay then clients you currently have a stay with or repeat clients can call you from the app, while Anytime means current and repeat clients as well as unbooked/unconfirmed clients can call you thru the app. If you select Never then there is no option to call you. You can further select that option on a client by client basis, so you could select "never" now, but if there's a client you want to be able to call you, you can change the settings on the clients booking page.
