Why the phone still matters for a restaurant
Guests call to ask if you have a table at eight, whether the patio is open, if there's parking, and whether the risotto has mushrooms. Those calls come in at the same moments your host stand is busiest. An AI phone host takes the routine ones off the floor, so the people at the door can look after the people at the door.
How availability works
Apollo keeps the reservation book itself. You tell it when you're open each day, how many tables can be booked in one slot, the largest party one table seats, and how long a slot lasts. When a guest asks for a time, the agent checks that slot first and only books if it's inside your hours and has room. It reads the date, time and party size back before it confirms.
What it doesn't do yet
It books new reservations and adds guests to the waitlist. It doesn't change or cancel an existing booking over the phone, because it can't yet prove the caller is the person who made it. Those calls go to your team, and you change or cancel the booking from the dashboard. It also doesn't sync with outside reservation platforms; Apollo's own book is the source of truth.
Test it on a busy Friday before it takes one
Readiness tests have an AI caller ring your agent and grade the result: it asks what the agent can do, insists on a person, and tries to pull it off topic. Add your own scenarios too (up to 20 per agent), like a guest who wants a table at a time you're closed or asks whether a dish has nuts. Each scenario has to pass 3 runs in a row. You can also share a talk link so your staff can try the agent in a browser. Read more in how to test a voice agent before it takes real calls.
