If you don't see **Agent Studio** in the left menu, contact your account team. The AI Voice Agent is currently unavailable to customers in the UK. ## Before you begin Read [AI Voice Agent Overview](/s/article/ai-voice-agent-overview) first. It explains how an agent is organized into workflows, intents, segments, and actions. ## What the agent can do during a call For each segment, you choose one of these actions: | Action | What happens | | :- | :- | | Qualify | Asks one question and sorts the caller into a segment. It doesn't transfer or end the call. | | Inform | Gives the caller information, with no transfer. | | Inform & Route | Answers the caller's question, then transfers them to the phone number you set. | | Request Callback | Collects the caller's number, preferred time window, and reason, and saves them to the call record. The agent doesn't place the call; a person or your outbound team follows up. | | Support & Escalate | Tries to resolve the caller's issue using your knowledge sources. If it can't, it transfers to the phone number you set. | | End Call | Speaks a closing line, then hangs up. | On every call, the agent can also: * Answer questions from your Knowledge Sources. This is a default action and is always on. * Use what Invoca knows about the caller's web journey, such as the last page they visited, when **Utilize Digital Journey Context in Conversations** is turned on. * Collect details from the caller into the info fields you choose under **What To Collect**. Captured fields can be sent to other systems through integrations or custom webhooks. * Fire the Signal you attach to an action when that action completes, so the outcome appears in your reports. ## Key terms | Term | What it means | | :- | :- | | Agent Studio | The area of Invoca where you build and manage AI agents. | | Agent Name | An internal name for the agent, used in your agent list and campaign setup. Callers don't hear it. | | Brand Name | The name the agent uses for itself and your company during calls. | | Brand Conversation Rules | One-line rules the agent follows on every call, such as required disclosures or topics to avoid. | | Workflow | How the agent behaves on one channel. The Voice workflow holds the intents, segments, and actions. | | Intent | A reason for calling, described in plain language so the agent can recognize it. | | Qualify | An action that asks one question to sort callers into segments. | | Segment | A group of callers within an intent, defined by their answer to the Qualify question. | | Action | What the agent does for a segment. | | What To Collect | The info fields the agent asks for and saves on the call. | | Signal | An outcome tag that fires when an action completes. | | Knowledge Sources | Web links and documents the agent can use to answer questions. | | Preview Chat | Starts a live test call to the draft version of your agent. | | Draft and Go Live | Your changes stay in the draft until you select Go Live, which pushes them to production. | ## How the AI Voice Agent relates to the AI Messaging Agent The AI Voice Agent handles live phone conversations, and the AI Messaging Agent handles text conversations. The AI Voice Agent can use the same AI framework as your AI Messaging Agent, so you can reuse the same training data, conversation patterns, and conversion workflows. ## Related topics - [AI Voice Agent Overview](/s/article/ai-voice-agent-overview.md) - [Activate Your AI Messaging Agent in Invoca](/s/article/activate-your-ai-messaging-agent-in-invoca.md) - [Building Your AI Messaging Agent in Invoca](/s/article/building-your-ai-messaging-agent-in-invoca.md) - [Agent Voice ID](/s/article/agent-voice-id-overview.md) - [AI Voice Agent Actions](/s/article/ai-voice-agent-actions.md)
