Same-thread context
Agents see chat history, order notes, and bot transcript before they answer — unlike a blind PSTN call.

WhatsApp Calling for Business
WhatsApp calling for business is voice (and expanding video) inside the same Cloud API thread as your chats. Customers tap call on your business profile; agents see prior messages before they pick up. User-initiated calls are widely available; business-initiated calls need consent and are blocked in some countries. You still need a 2,000+ daily messaging limit and calling enabled on the number.
Keep the sale in WhatsApp. Add official Business Calling so support and sales can jump from chat to voice without asking the customer to dial a separate number — then send the follow-up template in the same thread.

Key Capabilities
User-initiated calls
Customers tap call on your business profile or in the thread wherever Cloud API calling is enabled.
Business-initiated calls
Outbound WhatsApp calls need prior user consent. Blocked in USA, Canada, Egypt, Vietnam, and Nigeria — India supports inbound and outbound.
Routing with the shared inbox
Send the call to the assigned owner or a calling queue instead of whoever has the founder’s phone.
After-call follow-up
Drop a Utility summary, payment link, or ticket note in the same conversation when the call ends.
Policy-safe by default
Official Cloud API calling — not grey VoIP apps, not call blasting from a personal WhatsApp.
Popular Use Cases
High-intent sales
Close a quote or site visit on a voice call without leaving the WhatsApp lead thread.
Complex support
Jump to voice when a chatbot or agent cannot finish troubleshooting in text.
Relationship verticals
Real estate, education counselling, and healthcare intake — voice plus a written recap.
Frequently Asked Questions
What is WhatsApp calling for business?
It is Meta’s WhatsApp Business Calling API: voice calls over VoIP inside the same Cloud API conversation as your messages and templates. Agents keep chat context; customers never leave WhatsApp.
Do I need the WhatsApp Business app to receive calls?
No. Calling on Cloud API is handled in your BSP inbox (Ominiflow) once Meta has enabled calling on the number. The free Business app is a different, single-device product.
Can my team call customers on WhatsApp first?
Only with prior user consent, and not in every country. Business-initiated calling is blocked in the USA, Canada, Egypt, Vietnam, and Nigeria. User-initiated (customer calls you) is the safe default worldwide.
What are the setup requirements?
A verified Cloud API number, typically a 2,000+ daily messaging limit, calling enabled by Meta on that number, and a BSP that surfaces calling in the team inbox. Details: https://ominiflow.com/blog/whatsapp-calling-for-business-guide
Does WhatsApp calling replace a phone system?
No. It sits beside PSTN and AI voice. Use WhatsApp calling when the customer is already in the chat thread; keep a regular number for people who never installed WhatsApp.
