WhatsApp Calling with anynode
Direct customer communication through a familiar channel – now fully integrated into the existing SIP infrastructure
The WhatsApp Business API was originally developed for sending large volumes of messages – calls were not initially intended. Now that WhatsApp Calling is officially available, anynode enables seamless integration of these calls into existing communication workflows.
With WhatsApp Calling in anynode 4.14, companies can receive voice calls from WhatsApp directly within their existing telephony and service environments. The feature uses the official WhatsApp Business Calling API and processes calls like regular SIP sessions – secure, reliable, and centrally manageable. This creates an additional contact channel that many people already know and use every day – without additional apps, gateways, or special clients on the company side.
Why this is relevant
Customers today expect simple and immediate ways to get in touch with a company. WhatsApp is one of the most widely used communication channels worldwide, and many people prefer it over a traditional phone call – especially when it comes to support or follow-up questions.
With WhatsApp Calling, companies expand their inbound channel without changing internal processes: calls arrive exactly where existing workflows and teams already operate.
