What is an agent?
An agent is your AI-powered virtual receptionist. It answers phone calls, speaks naturally with callers, retrieves information from your knowledge base, and can transfer calls or trigger actions via connected tools. Each agent is fully independent with its own:- Instructions — personality, behavior rules, and conversation guidelines
- Voice — the speaking voice callers hear
- Knowledge base — documents and website content for answering questions
- Call flow — visual routing logic for transfers and conditional behavior
- Tools — external APIs the agent can invoke during calls
- Phone number — a dedicated inbound number linked to the agent
