WhatsApp Voice Calling — Message and Call in One Thread
Customers can call your business from WhatsApp without leaving the chat. Your team handles inbound calls and permission-based outbound calls on the same verified number you use for messaging, broadcasts, and inbox — powered by Meta's WhatsApp Business Calling API.

What is WhatsApp voice calling on CampaignHQ?
WhatsApp voice calling lets businesses receive and place VoIP calls with customers on the same WhatsApp Business number used for messaging. On CampaignHQ, calling sits alongside your shared team inbox, chatbots, and automations — so a chat can escalate to a voice conversation without switching apps or losing context.
Meta supports two paths: user-initiated calls (customers tap call in WhatsApp) and business-initiated calls (your team requests call permission inside an active conversation, then places the call). Both run on the official WhatsApp Business Platform Cloud API.
Same number
Voice and messaging on one verified WhatsApp Business number.
In-thread escalation
Move from chat to call without leaving the WhatsApp conversation.
Agent-ready
Route calls through your team inbox and support workflows.
Phone tag vs in-app WhatsApp calling
Customers already message you on WhatsApp. Native calling keeps support in the channel they trust — no separate phone line or callback number.
Disconnected support
Chat here, call somewhere else
- Customers copy a phone number and leave WhatsApp
- Agents lose chat context when switching to PSTN
- No record of call intent in the messaging thread
- Harder to tie calls back to campaigns and bots

Outbound calls
Call back with explicit permission
For business-initiated calls, CampaignHQ follows Meta's permission flow — request approval in an active conversation, then place the call within the allowed window once the customer opts in.
- Permission requests inside open conversations
- Compliant outbound calling per Meta limits
- Ideal for sales follow-up and high-intent support
- Works alongside templates and automation steps
