Where WhatsApp Calling Is Available and Which Providers Support It

WhatsApp Business Calling lets a company receive and place voice calls inside the WhatsApp app itself, with no 1-800 numbers and no PSTN. Before turning it on, it helps to understand the real map of countries with WhatsApp Calling and the providers that support it, because availability is not uniform: it depends on who starts the call.

Inbound vs. outbound: the distinction that changes everything

There are two call types, governed by different rules:

• Inbound (user-initiated): the customer starts the call by tapping the call button on your business profile. Available in virtually every country where Meta's Cloud API operates, and it is free.
• Outbound (business-initiated): your business starts the call to the customer. It is paid, requires prior customer consent, and has broad coverage with a few exceptions.

This is the point that trips people up: a country can allow inbound calls without any issue and still block outbound.

Countries where outbound is NOT available

As of now, business-initiated outbound calls are not enabled when the business number belongs to:

• United States
• Canada
• Egypt
• Vietnam
• Nigeria

In these cases inbound still works: customers can call you, but you cannot start the call over WhatsApp. There is also a gray zone in Turkey and some Gulf countries (such as the UAE or Saudi Arabia), where certain providers restrict outbound; there it is best to verify case by case with your BSP.

Regions excluded by sanctions

Due to international regulation, WhatsApp Business Platform does not operate in sanctioned regions: Cuba, Iran, North Korea, Syria, and the areas of Crimea, Donetsk and Luhansk. There is no Cloud API there, and therefore no WhatsApp Calling in either direction.

Availability at a glance

Providers are global, not country-specific

A common misconception is to look for "the WhatsApp Calling provider in my country." In reality, the feature is enabled by global BSPs (Business Solution Providers) running on the same Meta Cloud API. The same provider can serve a business in the US, in Spain, or in India.

Requirements to activate WhatsApp Calling

Regardless of country, you need:

1. A number on the Cloud API, not on the WhatsApp Business app or regular WhatsApp. Once a number is migrated to the API, it no longer works in the app.
2. Customer consent for outbound calls, logged and demonstrable.
3. Audio over WebRTC/SIP: there is no interconnection with the traditional telephone network (PSTN).
4. Meeting the platform's operational threshold (advanced capabilities unlock past a minimum volume of conversations in a 24-hour window).

How to choose a provider

Since they all run on the same API, the differentiator is not "who has WhatsApp Calling," but what each builds on top: a unified inbox, CRM, automations, reporting and, above all, what they do with the voice channel. That is where an inbound call stops being just a ringing phone.

Where AI voice fits in

Answering every live call does not always scale. On top of WhatsApp Calling, Omnifox adds an AI voice agent and IVR that picks up the inbound call, understands the customer, routes by language, and resolves or transfers to a human, all within the same thread and alongside the rest of your channels (Instagram, Messenger, Telegram, Webchat, SMS) and your sales CRM.

Frequently asked questions

Do I need a provider based in my country? No. BSPs are global and enable the feature on the same Cloud API, regardless of where your business is registered.

Do inbound calls cost anything? No. Calls started by the customer are free in supported countries.

Can I call customers without permission? No. Outbound requires prior, logged and demonstrable consent; calling without it violates Meta's policies.

Does it work with my current WhatsApp Business number? Only if you migrate it to the Cloud API. Once migrated, the number stops working in the app and is managed through the API or a platform like Omnifox.

Does it replace my phone system? No. It is voice over data (WebRTC/SIP) with no PSTN interconnection, designed to handle calls inside WhatsApp, not to replace your traditional telephony.

In short

• Inbound: almost everywhere, free.
• Outbound: broad, except the US, Canada, Egypt, Vietnam and Nigeria, plus the Turkey/Gulf gray zone.
• Providers: global, not country-specific.
• Requirements: a number on Cloud API, consent for outbound, and audio over WebRTC/SIP.
