Agent
An AI-powered virtual assistant configured to handle phone conversations for a specific business workflow.
In Stellar, an agent is a fully configured AI voice assistant designed for a specific task: qualifying leads, booking appointments, confirming events, or handling inbound calls. Each agent has its own system prompt, knowledge base, voice settings, and workflow logic.
Agents operate autonomously once deployed. They answer or place calls, follow conversation flows, make decisions based on caller responses, and execute actions like booking calendar slots or updating CRM records. All of this happens without human intervention.
The key difference between a traditional IVR system and an AI agent is flexibility. IVR follows rigid menu trees. An AI agent handles natural conversation, adapts to unexpected questions, and can reference business-specific documents to give accurate answers.
