- Inbound ringing via browser push notifications.
- Outbound dial-out from the agent UI.
- A live call card surfaced in the inbox.

Call permission gate
Customer pre-authorisation, handled
WhatsApp blocks outbound calls unless the customer has pre-authorised your business to call. WBIZ wires the call-permission request into the inbox toast, with a 7-day permission window, so when an agent dials out the gate is enforced and re-requested cleanly.
- A call-permission request wired into the toast.
- A 7-day customer permission window, tracked.
- Handles the call-permission error codes automatically.
- Permission state surfaced on the contact.

Calls and chats in one surface
Calls live next to the same conversation thread
Inbound and outbound calls attach to the conversation thread they belong to, so call history sits right alongside chat history, in the same agent surface with the same contact context. Outbound-call UI polish and a reconnect flow are deferred, but the core call path is live today.
- Call history per conversation thread.
- The same agent UI as the inbox.
- A push notification on every inbound ring.
- Live now, with no waitlist, no flag and no beta.

The end of "please call us at this number"
Customers call your business number on WhatsApp directly. WBIZ wires up the WebRTC signalling, the call-permission gate, the push for inbound ringing, and the in-app call UI. Production needs HTTPS and a TURN server. The core path is live; outbound-call polish and reconnect are on the way.
Permission gate
The pre-authorisation flow surfaced in-app, with a 7-day permission window.
Call history per thread
Every call attaches to the conversation thread, so chat and voice sit next to each other.
FAQ
Calling, answered
Is WhatsApp voice calling live in WBIZ today?
Yes, live now, not behind a flag and not on a waitlist. The implementation is real WebRTC, with an SDP offer and answer plus trickle ICE signalling, inbound ringing via push, outbound dial-out from the agent UI, and a live call card inside the inbox.
Why is an outbound call sometimes blocked?
WhatsApp requires customer pre-authorisation for outbound calls. WBIZ wires the call-permission request into the in-app toast and tracks the 7-day permission window per contact, so the gate is handled cleanly when it triggers.
Do I need any infrastructure to run calls in production?
Two things. The calling page must be served over HTTPS, which the browser requires for WebRTC, and a TURN server is needed so calls work across NAT and firewalls. Both are operational requirements you arrange in your hosting.
Can I record calls?
Call recording, transcription and queueing are not shipped today. The core call path is live, and recording and QA workflows are on the roadmap.
Do customers need to install anything new?
No. Voice calling happens inside the same WhatsApp app they already have. They tap to call your business number directly inside their existing WhatsApp conversation.
