On the call

Feels like talking to a person.

Natural back-and-forth for the caller, full control for your team.

  • Natural conversation

    Real time · interruptions

    Replies in real time and lets the caller cut in mid-sentence — it stops, listens and carries on, instead of talking over them.

  • Live call monitor

    Listen · whisper · take over

    Watch calls as they happen. Listen in, whisper guidance to the AI, put the caller on hold, transfer, or take the call yourself.

  • Transfer or take a message

    Warm transfer · tasks

    Hands callers to the right department or number. If nobody picks up, Aiva Chat takes a message and creates a task for your team.

Architecture

How a call flows through Aiva Chat.

Five steps from ring to reply — and what happens at each one.

  1. Customer dials

    Your number, bought in the dashboard or linked from Twilio. Aiva Chat answers 24/7 — or after your desk phones ring first.

  2. Language matched

    Auto-detects the caller’s language, or uses the one you pinned.

  3. Context loaded

    Your knowledge base and business hours — plus the caller’s HubSpot contact, if connected.

  4. Actions taken

    Books a free time (checked against your hours, staff and Google Calendar), sends a Stripe payment link, transfers, or calls your custom action.

  5. Aiva Chat speaks

    Replies in real time and handles interruptions. After the call: transcript, summary and outcome.

Real-time replies — and the caller can interrupt at any point, just like with a person.

Voice FAQ

Yes — natural speech that replies in real time, with 10 voices to choose from. It handles interruptions gracefully instead of talking over the caller.

Buy a number in the dashboard (US, Canada, UK or Australia), or bring in any number you already have on your Twilio account with Sync Twilio — that’s the way to use a number from another country, such as India. Want to keep your current business line? Our team helps you port it — porting is a manual process, so allow some time.

By default it auto-detects the caller’s language and replies in it. You can also pin one of 13 — English, Hindi, Gujarati, Spanish, French, German, Italian, Portuguese, Dutch, Arabic, Mandarin, Japanese or Korean — or use bilingual mode.

Yes, with or without a connected calendar. It checks your hours, staff and rooms, its own appointment book and, if you’ve connected Google Calendar (through a service account today), that calendar’s busy times, offers open times and books one — or, for services that need your approval, takes a request. Callers can ask for a specific staff member where the service allows it, and confirmation texts and reminders follow automatically. See how bookings work.

Yes. Aiva Chat warm-transfers to the department or number you choose. If nobody answers, it takes a message and creates a task. Your team can also listen in, whisper or take over live from the call monitor.

Yes — single calls or bulk outbound campaigns from a CSV or your contacts, with do-not-contact checks and an 8am–9pm calling window.

Calls can be recorded through Twilio. Before any recording starts, the caller hears a spoken recording notice. Every call also gets a transcript, a summary and an outcome label.

Immediately, 24/7 — no hold music, no menu tree. You can also have your desk phones ring first and let Aiva Chat catch the rest, with business hours and an after-hours mode.
