AI voice agent for WhatsApp calls: what to check before you buy

Customers already call businesses on WhatsApp. An AI voice agent answers those calls for you. It needs the number to run on Meta’s WhatsApp Business Platform, through the Business Calling API, because the WhatsApp Business app rings a phone and waits for a person. Customers keep calling from WhatsApp as usual.

A good AI agent is not a chatbot reading a menu. It holds a natural conversation, understands what the caller wants, and does it, or passes the call to the right person.

Use this as the minimum bar.

• Answer every call straight away, including several at the same time
• Speak the caller’s language, with a natural voice and no lag
• Answer only from your information, and say so when it doesn’t know
• Do real tasks: confirm orders, book appointments, check deliveries, create callbacks
• Connect to your systems through an API you control
• Say it is an AI
• Hand to a person when the caller asks or is upset
• Leave a summary and an outcome for every call

Demos are easy to polish. Before you commit, call it yourself, in the languages your customers use, with the awkward questions they really ask.

• Voice: does it sound like a person, without pauses that make callers talk over it?
• WhatsApp calls: does it answer WhatsApp voice calls, or only WhatsApp messages?
• Actions: can it complete tasks during the call, or does it only take notes?
• Handoff: where does the call go when a person is needed, and on which device do they answer?
• Control: can your team listen live, whisper, take over and hand back?
• Fallbacks: queues, keypad menus, opening hours and voicemail around the AI
• Data: recording consent, retention, access rules and where data is hosted
• Number: what happens to your WhatsApp Business app on that number
• Price: what is included, what each extra minute costs, and what Meta bills directly

Dialaunch is an AI agent for WhatsApp calls, with your team in control. It answers every WhatsApp call, in any language your customers speak, in HD voice with no lag, using what you teach it: your website, your catalogue and your own answers. It confirms orders, books appointments in Google Calendar, checks deliveries, creates callbacks and calls your systems through an API you connect. It says it is an AI, and it transfers to your team when the caller asks or is upset. Every call gets a summary, key moments and an outcome.

Your team can listen to any call live, whisper, take over in one click and hand the call back to the AI with the full context. Handoffs ring on the phone your team already uses: their own WhatsApp, a SIP desk phone or softphone, or the browser. Around the AI sit keypad menus, queues with hold music, opening hours with holidays and time zones, voicemail, fallbacks and reporting, and you place the AI wherever you want in the flow.

The same AI can answer your regular phone line through your own SIP trunk, and WhatsApp, Instagram, Messenger and email messages land in a shared inbox. EU hosting is available, recording is off by default with a consent message and automatic deletion, and Dialaunch is GDPR-ready.

Setup takes about 15 minutes on your side with a guided flow, and Meta’s approval of the number can take 1 to 3 days. Once connected, the number stops working in the WhatsApp Business app and the app’s chat history doesn’t move over, so you can connect a different number if you want to keep the app.
