Voicemail vs answering service vs AI receptionist
Every clinic misses calls: during treatments, at lunch, in the evening and at weekends. There are three ways to handle them. Here's an honest look at each, including where an AI receptionist isn't the right fit.
The problem with missed calls
When a business doesn't answer, many callers simply don't leave a message. In a 2025 survey of 1,000 consumers by CallRail, only 42% said they leave a voicemail, 21% said they immediately call another business, and 78% said they had taken their business elsewhere after failing to get through by phone. It was a US survey and it measures what people say rather than what they do, but anyone who has listened to a quiet voicemail inbox on a Monday morning will recognise it.
For a clinic, one lost new patient can be worth hundreds or thousands of pounds, so the question is which option catches the most of those calls for a sensible cost.
At a glance
| Voicemail | Answering service | AI receptionist | |
|---|---|---|---|
| Who answers | Nobody. A recording. | A person at a call centre, reading your notes. | An AI voice trained on your clinic's facts. |
| Available | 24/7 | Depends on the plan. Often office hours plus extra for evenings and weekends. | 24/7, including several calls at once. |
| Can answer questions | No | Basic ones from a script. Usually not detailed treatment or price questions. | Yes, from the treatments, prices and policies you give it. Takes a message for anything else. |
| What you get | A message, if they leave one. | A message by email or text. | An email with name, number, reason, best time and the full transcript. |
| Callers who hang up | Many | Few | Few |
| Medical advice | n/a | Should never give it | Never gives it. Worried patients are flagged urgent. |
| Typical cost | Free | Monthly fee plus per call or per minute charges. | A flat monthly fee. |
1. Voicemail
Good for: clinics that rarely miss calls, or whose callers are mostly existing patients who will happily leave a message.
The catch: new enquiries are the callers least likely to leave a message. They're often ringing several clinics, and the first one that answers tends to get the consultation. You also don't know who rang and hung up unless you check call logs.
2. A human answering service
Good for: clinics that want a real person on every call and are happy with a message-taking service.
The catch: the person answering is usually covering many businesses from a script, so detailed questions about treatments, prices or finance often get "someone will call you back". Pricing is commonly a monthly fee plus a charge per call or per minute, so a busy month costs more, and evening and weekend cover may be extra.
3. An AI receptionist
Good for: clinics that get a steady flow of enquiries outside the times someone can answer, and want those callers to get real answers straight away.
A well set up AI receptionist answers in your clinic's name, handles common questions from the facts you give it (treatments, price ranges, finance, consultations), takes appointment changes for your team to confirm, and emails you every caller. It answers every call at any hour, and several at once.
The catch: some callers would always rather speak to a person, so it should be honest that it's an AI and always offer a callback. It should never give medical advice or confirm bookings it can't see. And it's only as good as its setup: an AI that doesn't know your prices or policies will frustrate people, so it needs building around your clinic and checking regularly.
Which should you choose?
- Hardly any missed calls? Voicemail is fine.
- Want a human voice and only need messages taken? An answering service works.
- Missing new enquiries in the evenings, at weekends or during treatments? An AI receptionist catches them and answers their questions, usually for less than a person.
Whichever you choose, you keep your existing number. All three work by diverting the calls you can't answer. Our guide to diverting calls shows how on BT, mobiles and cloud phone systems.
