WhatsApp Calling
WhatsApp Calling — inbound and outbound, in the browser
Most WhatsApp Business platforms only handle text. FlowsDesigner integrates with Meta's WhatsApp Calling API via SIP trunks, so agents take and make calls right in the dashboard.
What's inside
What you get
- Inbound: customers calling your WhatsApp number ring directly in the agent's browser
- Outbound: click-to-call from any conversation, dial out to the customer's WhatsApp
- TLS-secured media (TURN-TLS-443) — works behind any firewall
- Mute, hold, end — standard controls
- Per-WhatsApp-number trunk provisioning, set up in one click
No second phone needed
Agents work from their browser. No softphone, no dial pad, no WhatsApp Desktop — calls open inline next to the conversation.
Works behind corporate firewalls
Media is forced through TLS port 443 via TURN relay, so it traverses firewalls that block UDP RTP.
Common questions
Does WhatsApp Web (Baileys) support calling?+
No. Only the official WhatsApp Business Cloud API supports calling. WhatsApp Web / QR-linked numbers cannot make or receive SIP calls.
