What you get with the WhatsApp Calling integration

Built on Meta's WhatsApp Business Calling API with the same voice AI stack we use for PSTN telephony.

Native WhatsApp Calling API

Built directly on Meta's WhatsApp Business Calling API. Inbound calls flow over WhatsApp's WebRTC infrastructure — no PSTN, no Twilio account, no separate line.

<500ms Voice Latency

Native audio LLMs (Gemini Live 2.5, OpenAI Realtime) bypass STT/TTS for sub-500ms response times — fast enough for natural conversation on WhatsApp's WebRTC link.

24+ Languages

Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati and 18+ more, plus English with Indian accent support. Auto-detects Hinglish.

Function Calling Mid-Call

Agent fetches order status, books appointments, updates CRM mid-call. Salesforce, HubSpot, Zoho, Google Sheets, or any REST API.

Automatic Webhook Setup

Link an agent in the dashboard and Edesy programmes Meta's per-number webhook automatically. No copy-pasting URLs into the Graph API.

Same Agent, Multiple Channels

The agent you build for WhatsApp Calls works on PSTN telephony, SIP, or WebRTC widget without rebuilding. One config switch.

Recordings, Transcripts, Analytics

Every call recorded, transcribed, tagged with structured outcome. Searchable history and dashboard out of the box.

Pairs with WhatsApp Messaging

Combine voice with WhatsApp message follow-ups — call summary, payment link, or appointment confirmation sent immediately after the call ends.

WhatsApp Calling integration FAQs

Do I need a Twilio or Plivo account for WhatsApp calling?

No. WhatsApp Business Calling uses Meta's WebRTC infrastructure directly — calls do not touch the public phone network, so no Twilio, Plivo, or Exotel account is required. You only need a WhatsApp Business account and a phone number that isn't already on personal WhatsApp.

How is this different from /ai-voice-assistant/integrations/whatsapp?

That page is about voice → WhatsApp messaging fallback (when a regular phone call goes unanswered, send a WhatsApp message). This page is about an AI voice agent that picks up actual WhatsApp Business calls. Different feature, different setup. Most customers use both.

Can I make outbound WhatsApp calls?

Outbound business-initiated WhatsApp calls require Meta's messaging tier of 2,000+ unique users/day. Until then, most customers use traditional telephony for outbound and WhatsApp calling for inbound.

What does inbound WhatsApp calling cost?

Edesy charges standard voice agent rates (₹4/min pay-as-you-go, or monthly plans from ₹1,499). Meta does not currently charge for inbound user-initiated WhatsApp calls. There is no separate channel premium.

How long does setup take?

Under an hour for a working test setup. Full production also requires Meta Business Verification (1–14 business days). Our setup guide covers every step with screenshots.
