What is AI phone agent?

An AI phone agent is software that handles phone calls in a natural spoken voice, answering inbound calls and placing outbound ones, without a human on the line. It listens, responds in real time, and completes tasks like booking or confirming an appointment.

AI phone agent is a common synonym for "AI voice agent" or "AI receptionist," with the emphasis on the phone channel specifically. In healthcare, an AI phone agent answers patient calls 24/7, books into the EHR, and escalates urgent calls to staff.

Echo is an AI phone agent for healthcare that runs both inbound answering and outbound campaigns (reminders, recalls, waitlist offers), is HIPAA-compliant, and speaks 70+ languages.

Hear it for yourself

A real call from inquiry to booked appointment.

Press play and read along. Echo answers, switches language mid-call, reads live openings straight out of the calendar while it is still talking, then writes the booking back into it. Nothing is left queued for staff to finish afterwards.
