Short answer: Plenty of restaurants still take bookings only by phone, or keep their best slots off the booking apps. With OsmO connected to your AI app, you type the request once and OsmO places the call: it asks for your date, time and party size, offers the backup times you gave it, and reports back what the restaurant said.
Give one clear request: the restaurant, the day, the time, how many people and any backup times.
You usually do not need the number: your AI app or OsmO looks up the listed one.
Keep card details out of the request. If the restaurant wants a deposit, you can finish that part yourself.
An answered call uses 3 credits; your 50 free credits cover about 16 calls.

The full guide
What to tell your AI
Imagine a friend is ringing for you and you have ten seconds to explain. These four details cover almost every booking:
- Which place: the name and the area, for example "Marlow's on 5th Avenue".
- When: the day and time you want, plus one or two times you would also accept.
- How many: the party size, and whether you need a high chair, step-free access or a quiet table.
- Whose name: the name the booking should go under.
What happens on the line
- Your AI app checks the details with you and asks OsmO to place the call.
- The restaurant's listed number is looked up (by your AI app, or by OsmO itself in ChatGPT, Claude, Grok and other connector apps) and dialled from the OsmO number for your country.
- If a phone menu answers, OsmO listens and picks the reservations option.
- It asks for your first choice, then your backups, and confirms the name and party size.
- When the call ends, your AI app shows what was agreed and anything you still need to do.
When it is better to ring yourself
Some bookings are better done in person. If a restaurant asks for a card number to hold the table, leave that to you: keep card details out of the request, and OsmO reports what the restaurant needs so you can finish it. The same goes for big events where the venue wants to talk through a menu or a contract.
Tip: if you are flexible, say so. "Any time between 7 and 9" gives the restaurant more room than a single slot and makes a yes more likely.
What it costs
An answered call uses 3 credits however long it lasts, and a call nobody answers is free. The 50 credits you get on sign-up cover about 16 answered calls. If the restaurant does not pick up, nothing is charged and you can ask your AI to try again later.
Questions people ask
Do I need the restaurant's phone number?
Usually not. Give the name and the area: your AI app can look the number up, and in ChatGPT, Claude, Grok and other connector apps OsmO finds the listed number itself. If you already have it, give that instead.
Can it call several restaurants at once?
Yes. Your AI can call several places in a row, and in ChatGPT, Claude, Grok and other connector apps OsmO can ring up to five numbers from one request, then you compare the answers.
Does it cost more if I am kept on hold for a long time?
No. An answered call uses 3 credits whatever its length, so a long hold costs the same as a short call.
Which countries does it work in?
You can sign in with a mobile number from the United States, Canada, the United Kingdom or Australia (India too). Calls are placed from the OsmO number for your country.
