A customer taps the call button in your WhatsApp chat, and your agent picks up — the same agent, with the same voice, knowledge and tools, that answers your phone line and your website. No phone number to rent, and nothing for the customer to install: they are already in the chat.

​
Turning it on

  1. On Connect WhatsApp, press Calls on the number.
  2. Switch on WhatsApp calls and save.
That is all. Switching it on also turns on Answer calls for the agent on that number, and gives it a voice if it had none. Its WhatsApp row on the Voice page shows On — it follows this switch, and every agent has it on by default.
The WhatsApp calls switch is the one that decides. While it is off, this number answers no calls — even if the same setting is on in Meta’s WhatsApp Manager. Switching it off turns the agent’s WhatsApp row off too, and leaves the website and phone as they are.

​
The settings

The settings are read from WhatsApp each time you open them, so a change made in Meta’s WhatsApp Manager shows up here too. Pick each time from the list, or type it however you like — 09:00, 9 am, 18:00 and 6 pm all work. Switching call hours off really turns them off at WhatsApp, even if you cleared the days first. Call hours are edited one range a day here. WhatsApp allows two a day; a second range set in WhatsApp Manager is kept as it is unless you edit that day. Customers don’t see your hours listed anywhere — not on your profile, not in the chat. They meet them when they call outside them: WhatsApp offers to chat or to request a callback, and shows when you’re next available. WhatsApp applies a change straight away, but a customer’s phone can take up to 7 days to pick it up; opening your business’s chat info page on that phone refreshes it at once. To test your hours, call from another phone at a time they’re closed.

​
Who can use it

WhatsApp only enables calling for businesses with a daily messaging limit of at least 2,000 people — unique people you start conversations with in a rolling 24 hours, counted across your whole business, not per number. Every new business starts lower. The quickest way up is verifying your business; otherwise Meta raises it as you send messages people engage with (how limits rise). The Calls window states your business’s limit. If it is under 2,000, it says so over its settings and holds the Save button until it is.
WhatsApp Manager may show an older per-number limit, often 250. That figure does not decide calling — the business-wide one does, and it is often already 2,000.
While WhatsApp calls is off, the other settings in the window are greyed out.

​
What it costs

A WhatsApp call is billed at your voice per-minute rate — the same as a phone call — for the time your agent is on it, rounded up to the next whole minute. Calls your customers make to you cost nothing from Meta.
