How does Fonazo's AI voice agent work?

Fonazo connects to your business phone number and WhatsApp. When a customer calls, Fonazo answers in under 3 seconds, understands their question in any of 40+ languages, checks your calendar or CRM if needed, books appointments, sends confirmations, and updates your tools — all during the live conversation. After the call ends, it creates CRM contacts and notifies your team automatically.

Is an AI voice agent worth it for small businesses?

Yes. Studies show 62% of business calls go to voicemail and 80% of callers won't leave a message — they call your competitor instead. For small businesses without a dedicated receptionist, an AI voice agent like Fonazo answers every call 24/7, captures every lead, and books appointments while you focus on running your business. Most teams see ROI within the first week of deployment.

Can an AI voice agent replace a human receptionist?

For routine tasks — answering common questions, booking appointments, qualifying leads, taking messages — yes. Fonazo handles these instantly, in any language, without breaks. For complex situations requiring human judgment or empathy, Fonazo seamlessly transfers the call to a team member with full context. Most businesses use Fonazo to handle the 80% of routine calls so human staff can focus on the 20% that need a personal touch.

What languages does Fonazo support?

Fonazo supports 40+ languages including English, Hindi, Hinglish, Tamil, Spanish, French, German, Portuguese, Arabic, Mandarin, Japanese, Korean, Russian, Italian, Dutch, Turkish, and many more. The agent can switch languages mid-conversation if a caller prefers a different language — no separate setup required.

How fast can I set up Fonazo?

Under 2 minutes. You describe your business in a chat, Fonazo asks the right questions and builds your voice agent automatically, then you connect your phone number or WhatsApp Business. No engineering team, no dashboard configuration, no IT department required. You can be answering calls within minutes of signing up.

Is my customer data secure with Fonazo?

Yes. Fonazo is SOC 2 Type II certified, HIPAA compliant, and GDPR ready. All calls are encrypted end-to-end. Three layers of real-time guardrails block prompt injection attempts, prevent data leaks, and keep the agent on-topic. Your customer data is never used to train our models, and you can delete recordings anytime.

How much does an AI voice agent cost?

Fonazo is currently in early access and pricing is not yet public. Waitlist members get founding member pricing — significantly below standard rates — plus white-glove onboarding. Compared to hiring a 24/7 receptionist (typically $30,000-$60,000 per year per person), AI voice agents are dramatically more affordable while never sleeping, never taking sick days, and handling unlimited concurrent calls.

What's the difference between Fonazo and an IVR system?

Old IVR systems make callers press 1 for sales, 2 for support, navigating menu trees that frustrate customers. Fonazo is conversational AI — callers just talk normally. 'I need to book an appointment for tomorrow morning' is understood and handled instantly, no menu navigation required. Fonazo also takes real actions like updating calendars and CRMs during the call, which IVR systems cannot do.

Does Fonazo integrate with my existing tools?

Yes — Fonazo connects to over 2,000 tools including Google Calendar, Gmail, HubSpot, Salesforce, Slack, Zoom, Microsoft Teams, Notion, Airtable, Twilio, WhatsApp, Shopify, Stripe, and more. The agent uses these integrations during live conversations to check calendars, book meetings, send confirmations, and update records in real-time.
