What you can build
Inbound reception
A phone number that answers instantly, qualifies callers, books appointments, and transfers to humans when needed.
Outbound campaigns
Automated calling campaigns with a parallel dialer, retry rules, calling windows, and voicemail handling.
Multi-step call flows
Visual flows with specialized agents, conditions, data collection, HTTP tools, and warm transfers.
Web voice & chat
Embed the same assistants as a voice or chat widget on any website.
Core concepts
How a call flows
- The call starts. A caller dials your number (inbound), or the assistant places the call from a campaign, a single test, or the API (outbound).
- The assistant listens. It follows what the caller says as they speak and detects when a turn is finished.
- It decides what to say. Its prompt or flow, plus any tools and knowledge base it has access to, produce the next reply or action.
- It speaks. The reply comes back in the assistant’s selected voice.
- It acts. It answers questions, collects information, books an appointment, or transfers to a person when the conversation calls for it.
- Everything is recorded. The transcript, recording, and outcome land in History automatically — ready to review or build an automation on.
Built for Europe
Consent announcements with optional recording are built in, and recording can begin only after the caller agrees. Calling windows and do-not-contact lists help teams follow their privacy and outreach requirements.Where to go next
