Calling ahead only gets you on the wait list. They do not do a true table reservation. I use the app on my phone know matter how big my party is. It always cuts the wait time.
Yes just call ahead to reserve a table
Yes call and reserve a table
Yes, you can call ahead the same day to reserve a table or get on the waiting list before you arrive. It's helpful, especially if you have a large group (more than 5 or 6). Make sure you check in at the reception desk upon arrival. And when you call, they can tell you how long it will be until your table is ready.
You can also use their app to reserve.
You may be able to do call ahead...each location may vary.
