How do you set iPhone to only ring for VIPs?

To set your iphone to only ring for VIPs, first, open the Contacts app and designate important contacts as VIPs by tapping "Add to VIP" under their contact details. Next, go to Settings > Notifications > Phone and turn off "Allow Notifications." Finally, enable "Do Not Disturb" mode and customize it by going to Settings > Do Not Disturb, allowing calls only from your VIP contacts. This will ensure that your phone only rings for those selected individuals.
