This article explains what the feature is, how it works, the requirements for using it in Indonesia, the types of calls available, estimated costs, and frequently asked questions. ## **1. What Is WhatsApp Business Calling API?** WhatsApp Business Calling API allows businesses to receive and make voice calls with customers using WhatsApp's Voice over Internet Protocol (VoIP) infrastructure rather than conventional telephone networks. These calls take place directly within an existing WhatsApp chat thread. This means that when an agent switches from chat to a phone call, the entire conversation history, order details, and previous interactions remain visible, so customers do not need to explain everything again. This feature complements the WhatsApp Business API (Cloud API), which many businesses in Indonesia already use to send and receive automated messages. **Why Is This Feature Relevant to Businesses in Indonesia?** Indonesia is one of the largest WhatsApp markets in the world, with more than 195 million active users. WhatsApp has become a primary communication channel between businesses and customers across almost every industry. However, there are situations where text messages alone are not enough — problems that are too complex to explain in writing, situations requiring reassurance that only a human voice can provide, or sales negotiations reaching a critical point. WhatsApp Business Calling API bridges this gap without requiring customers to leave the WhatsApp ecosystem they already trust. ## **2. Call Types: Inbound vs. Outbound** WhatsApp Business Calling API distinguishes between two types of calls, each with different rules. ### **Inbound Calls (User-Initiated)** - Customers tap the phone icon in your business chat, just as they would when calling a friend. - This is the primary use case for this feature. - **Free** for both businesses and customers, regardless of the destination country. - The phone icon can also be embedded in interactive messages or templates, allowing businesses to direct customers to call directly from a chat response. ### **Outbound Calls (Business-Initiated)** - Businesses **cannot call customers directly** without permission. - Businesses must first send a call permission request through WhatsApp. - Outbound calls can only be made after customers approve the request. - Outbound calls are charged per minute according to Meta's pricing structure (see the Estimated Costs section). - Read another article: [Choppy Internet Phone Calls?

How It Works and Key Features** - **Conversation context is preserved.** Calls and messages remain in the same thread, allowing agents to immediately access chat history, order status, and previous chatbot interactions when answering a call. - **Call icon control.** Businesses can show or hide the phone icon on their WhatsApp profiles. Businesses that are not yet ready to handle incoming call volumes can hide the icon until they are prepared. - **Routing to IVR or a contact center.** Incoming calls can be routed through an Interactive Voice Response (IVR) system or directly to a contact center, rather than ringing on just one phone number. This makes the feature suitable for business-scale operations. - **Verified caller ID.** Calls from businesses display the business name and verified badge, helping customers feel more confident about answering compared with calls from unknown numbers. - **DTMF support.** When integrated with an IVR system, the numeric keypad uses Dual-Tone Multi-Frequency (DTMF) signaling to let customers interact with automated menus during calls. ## **4. Requirements for Using WhatsApp Business Calling API in Indonesia** To activate WhatsApp Business Calling API, businesses generally need to meet the following requirements: 1. **Have a WhatsApp Business Account (WABA)** with a registered phone number in Indonesia or another supported country. 2. **Have a messaging limit tier of at least 1K**, meaning the account can send messages to at least 1,000 unique contacts within 24 hours. Meta and Business Solution Providers (BSPs) generally require this tier before calling features can be activated. 3. **Connect through an official Meta Business Solution Provider (BSP)** or, for certain businesses with direct partnerships, work with Meta's partner team through the Cloud API. 4. **Maintain a good phone number quality rating** (Medium or High), as the number's status and reputation can affect eligibility for advanced features such as calling. 5. **Have an approved use case**, generally falling under the Service, Utility, or Marketing categories, depending on the applicable BSP policies. > **Note:** Calling API availability among BSPs is being rolled out gradually. Some enterprise BSPs already offer full support, while other platforms are still in the process of adding this feature. Always confirm availability with your current BSP. ## **5. How to Activate WhatsApp Business Calling API** The general steps to activate WhatsApp Business Calling API are as follows: 1. **Make sure your WABA is verified** and has a messaging tier of 1K or higher. 2. **Contact your BSP (Business Solution Provider)** to confirm calling feature support and request activation for your account. 3. **Configure call routing** by deciding whether incoming calls should be forwarded to specific agents, a contact center team, or an IVR system. 4. **Enable the call icon** on your WhatsApp Business profile once your team is fully prepared to handle incoming call volumes. 5. **Test inbound call flows and outbound call permission requests** before going live with customers. ## **6. Estimated Costs** - **Inbound calls: Free** for both businesses and customers. - **Outbound calls: Charged per minute**, with rates determined by Meta based on the following factors: - Call duration, calculated in six-second increments and rounded up. - The destination country's calling code. - Monthly call volume. The more calls made to a particular country within a month, the lower the per-minute rate may become. These volume tiers reset every month. - Some BSPs charge additional service fees on top of Meta's rates, such as setup fees, hosting fees, or call markups. Therefore, it is important to ask your provider for a complete breakdown of costs. - Official rates may change at any time, so you should always refer to Meta's official pricing page or your BSP for the latest figures. ## **7. Use Case Examples** | Scenario | Benefits of Calling API | | --- | --- | | Confirming high-value orders or negotiating sales | Close deals faster through more personal voice interactions. | | Complex technical or financial issues | Agents can explain solutions directly without lengthy back-and-forth chat conversations. | | Identity verification or sensitive information | Customers may feel more comfortable sharing information by voice rather than text. | | Customer support requiring quick resolution | Escalate from chat to a phone call without losing the existing conversation context. | | Sales follow-ups (with customer permission) | Outbound calls with verified caller ID can improve answer rates compared with calls from unknown numbers. | ## **8. Frequently Asked Questions (FAQ)** > **Is WhatsApp Business Calling API different from the regular WhatsApp Business API?** Yes. WhatsApp Business API (Cloud API) focuses on text messages, media, and automated templates. Calling API is an additional layer on the same platform, specifically designed for voice calls. Both use the same WABA and WhatsApp chat thread. > **Do customers need to download an additional app to call a business?** No. Customers simply tap the phone icon within the WhatsApp chat they already use every day. > **Can businesses call customers at any time?** No. Businesses must first send a permission request through WhatsApp. Outbound calls can only be made after customers approve the request. > **Is this feature available to all businesses in Indonesia?** The feature is available to Indonesian business numbers that meet the messaging tier requirements and are connected through a BSP that supports Calling API. Availability may vary between BSP platforms because the feature is still being rolled out gradually. > **Can calls be recorded or integrated with existing customer service systems?** This depends on the BSP being used. Many enterprise BSPs support integration with contact centers, CRM systems, and IVR systems for call routing and call logging. > Pricing, requirements, and feature availability information in this article may change at any time in accordance with Meta’s official policies.
