Meta released the Cloud API Calling allowing user to call companies through WhatsApp. Companies have to be registered as WhatsApp business

This "API" was on beta in Brazil, Indonesia,etc. It is now globally available.
It is a highly requested feature, due to the public availability on WhatsApp.
It is important to associate this idea to another one "outbound whatsapp with RCX UI" https://ideas.ringcentral.com/forums/966594-ringcx/suggestions/48515087-outbound-whatsapp-within-rcx-agent-ui
it will allow to send messages directly to a customer while on call. (in this case, template are not required)
user initiated calls to business are free and there is a cost for business initiated. The pricing guide is attached to this initiative.
SIP with webRTC is available https://developers.facebook.com/docs/whatsapp/cloud-api/calling/sip
