We’ve all been there: typing feels too slow, but switching to a completely different channel to make a call is a hassle. Now, there’s a better way.
WhatsApp Cloud Calling BETA is now generally available on our business messaging platform WOZTELL. Your customer-facing teams can seamlessly switch from text chat to voice — all within the same conversation window. No hanging up, no redialing, no switching platforms.
Why This Matters
The numbers speak for themselves: 76% of consumers want the flexibility to switch between calling and messaging depending on their needs in the moment. The question was never whether customers prefer voice or text — it’s that they want both as an option.
Until now, the WhatsApp Business API didn’t support calling — only the Business App did. That meant businesses relying on the API for customer communication were limited to text, and had to direct customers to a separate phone line whenever a voice conversation was needed. Agents juggled multiple systems, and customers had to re-explain their issues from scratch. That costs time and patience.
WhatsApp Cloud Calling closes that gap.
What Can It Do for Your Business?
Replace Cold Calls with Warm, Permission-Based Conversations
Cold calls from unknown numbers suffer from low pick-up rates and low trust. WhatsApp Business Calling API flips that dynamic entirely. Because every call is preceded by at least one WhatsApp interaction a broadcast reply, a chatbot flow, and most importantly, a permission to call. Your sales team only calls leads who have already engaged. The call comes from a recognisable, verified WhatsApp Business profile, not a random number, and the full chat history is visible on screen before the agent even dials.
Real-world proof: Cartão de Todos reported a 26% increase in conversions and a 50% reduction in average conversion time after implementing WhatsApp Business Calling API over just one month.
Turn Your Hotline into a Smarter Customer Experience
Traditional IVR hotlines are costly, frustrating, and increasingly out of step with how customers want to communicate. With WhatsApp Business Calling API, you can replace the “press 1 for English” experience with a chat-first journey: a bot handles triage and simple queries, and a WhatsApp call is offered only when it genuinely adds value — escalating from the same thread, with full context already on screen.
The results speak for themselves. MyRepublic in Indonesia shifted 63% of call volume into WhatsApp, with CSAT up 13%. SICAR Solutions saw 20% faster case resolution and a 35% improvement in first-contact resolution.
