WhatsApp Voice AI

WhatsApp Calling on the Business API

The same number you use for messaging now answers voice calls with an AI agent.

User-Initiated Calls

Customers tap the call button on your verified WhatsApp number — call lands on the AI agent instantly. Works on WhatsApp mobile only (Meta restriction).

Real-Time Voice

Sub-500ms latency via Vertex AI–hosted Gemini Live or OpenAI Realtime. Native audio LLMs, no STT/TTS bottleneck.

Multilingual

All 22 Indian languages plus 100+ international. Native processing, not translation. Auto-detect Hinglish supported.

Same WABA, Same Number

Use your existing WhatsApp Business Account and phone number. No second number, no new business profile, no green tick re-verification.

Function Calling + CRM

AI fetches order status, books appointments, updates leads in your CRM mid-call. Connect any REST API.

Voice + Messaging Together

After the call, send WhatsApp messages with the call summary, payment link, or appointment confirmation. Both channels live on the same number.

From WhatsApp messaging to WhatsApp voice

If you're already on WhatsApp Business API, you're 30 minutes away from voice.

1

Have a verified WhatsApp Business number

If you already use WhatsApp Business API for messaging, your number is ready. If not, register a number under Step 2 in Meta's WhatsApp Business setup flow.

2

Enable calling via Graph API

POST to /<PHONE_NUMBER_ID>/settings with { calling: { status: ENABLED, callback_permission_status: ENABLED } }. Takes 30 seconds.

3

Generate a permanent System User token

Token never expires. Permissions: whatsapp_business_management + whatsapp_business_messaging. Documented step-by-step in our setup guide.

4

Connect to Edesy

Paste phone number, phone number ID, and access token into the Edesy dashboard. Link an agent. Done.

Comparing voice vs messaging on WhatsApp

WhatsApp Voice AI

  • Real-time spoken conversations
  • Higher engagement for emotional / urgent queries
  • Resolves complex issues in one turn
  • Accessible to low-literacy / non-typing users

WhatsApp Messaging

  • Asynchronous conversations
  • Rich media: buttons, lists, payments
  • Searchable conversation history
  • Works on weak data connections

Most businesses run both — voice for inbound enquiries, messaging for follow-ups, marketing campaigns, and rich-media flows.

WhatsApp Business Calling API FAQs

Is the WhatsApp Business Calling API the same as WhatsApp Cloud API?

WhatsApp Business Calling is a feature on top of the WhatsApp Cloud API (the messaging API). Same WABA, same phone number ID, same access token — calling is enabled per phone number with a single Graph API call.

Does WhatsApp charge for calls?

Currently Meta does not charge for user-initiated (inbound) WhatsApp Business calls. Business-initiated (outbound) calls require your account to reach a messaging tier of 2,000+ unique users/day and are subject to Meta's pricing.

Can I keep using my existing WhatsApp Business number?

Yes. If your number is already registered with WhatsApp Business API for messaging, you can enable calling on the same number. No second number required, no green-tick re-verification.

Does it work on WhatsApp Web or Desktop?

WhatsApp voice calls only work on the WhatsApp mobile app. WhatsApp Web and Desktop don't currently support placing voice calls. This is a Meta platform restriction, not Edesy's.

Where can I find the full setup walkthrough?

Our setup guide covers every Meta dashboard click and Graph API call with 19 screenshots. It's the same guide our customer support team uses.
