Agency

Autonomy level: autonomous system that can listen, speak, and hold natural phone conversations like a human... take actions such as booking appointments or updating systems without relying on rigid scripts or human intervention
“An AI voice agent is an autonomous system that can listen, speak, and hold natural phone conversations like a human. It uses speech recognition, large language models, and text-to-speech technology to understand callers, respond intelligently, maintain context, and take actions such as booking appointments or updating systems without relying on rigid scripts or human intervention.”

Human oversight: hands off to a person when the conversation calls for it
“AI phone agents handle repetitive, high-volume work like appointment booking, order status, and qualification, which frees your team for calls that need judgment or empathy. Most Retell AI deployments run a hybrid model: the voice agent takes the routine volume and hands off to a person when the conversation calls for it.”
