Turn WhatsApp into a full voice channel. Support.Monster brings the WhatsApp Business Calling API to your team — and our engineers integrate it with your CRM, tune the AI behind it, and keep it running.
The WhatsApp Business Calling API is Meta's official voice extension to the WhatsApp Business Platform. It lets businesses make and receive voice calls inside the same WhatsApp thread customers already use to message — with no separate phone line, no app switching and no carrier charge on incoming calls.
Support.Monster is a Meta Business Partner, so we handle the application, verification and configuration end to end. Once your verified WhatsApp number is connected, customers tap the call icon in WhatsApp to reach you, and you can call them back with consent — with your verified business name on display rather than an unknown number.
Messaging is fast, but some problems only get solved out loud. Calling inside WhatsApp gives you both without pushing customers off the app, into a phone tree, or onto an unknown number they will not answer.
Anyone can switch calling on. Making it resolve real problems means connecting your systems, training the agent on your own calls and watching it every week. That is what our engineers do.
Calls, recordings and outcomes land in Salesforce, Zendesk, Genesys or whatever you run — not in a separate dashboard nobody opens.
Transcription trained against how your customers actually speak, in their own language, rather than a generic model that fails on the first call.
When the AI should stop, your agent picks up mid-call with the full history — the customer never starts over.
