An average medical practice misses 30 to 40 calls per day — during lunch breaks, consultations or the Monday-morning surge. An AI phone assistant for appointment booking answers those calls around the clock, matches free slots against practice software such as Doctolib, samedi or the internal calendar, and sends each patient an SMS confirmation. For the medical assistant team this means far fewer phone interruptions, more time at reception and zero forgotten callbacks.

How it works in practice

01An incoming call is answered in English by the AI phone assistant within one ring.
02The AI identifies the request type: new appointment, rescheduling, cancellation or follow-up question.
03For appointment requests it asks for insurance type, reason for visit and preferred time window.
04It checks live availability against the practice calendar and offers three matching slots.
05After confirmation the appointment is booked, an SMS confirmation is sent and a reminder is triggered the day before.

Business case

An average two-physician practice in the DACH region handles roughly 600 calls per week, of which 18 to 25 percent stay unanswered. If only 60 percent of those missed calls are converted by an AI phone assistant into booked appointments, the additional monthly revenue ranges from 4,000 to 7,000 euros depending on fee schedule — at a bhomy Pro plan of 279 euros per month on annual billing.

Language models are obtained through an inference broker; the providers, some of them based in the USA, are disclosed in the DPA.
