Every business misses calls. The question is what happens to the caller when you do. In the UK there are three common answers: voicemail, a human call answering service, and, more recently, an AI receptionist. They are often sold against each other. In practice each is good at different things, and the right choice depends on what your callers actually need.
Voicemail
Voicemail costs nothing and needs no set-up. Its weakness is the caller's behaviour: many people hang up rather than leave a message, especially new customers who have other businesses to try. The ones who do leave a message often leave half the information you need, so the callback starts with questions.
- Best for: very low call volumes from people who already know you.
- Worst for: new enquiries, bookings, and anything time sensitive.
Human call answering service
A call answering service, sometimes called a virtual receptionist, is a team of people who answer your calls in your business's name, take a message, and pass it on. Some can book into a shared diary. Pricing is usually per call or per minute, often with a monthly minimum.
- Strengths: a real person on the line, good with upset or confused callers, and nothing to build.
- Weaknesses: cost rises with every call; receptionists work from a script and usually cannot see inside your systems; busy periods can still mean queues; and the quality depends on who picks up.
- Best for: businesses where many calls are sensitive or emotional, at modest volumes.
AI receptionist
An AI receptionist answers in natural speech, works out what the caller wants, and acts on it: answers the question, books the appointment into your system, or takes a complete message. It can answer any number of calls at once and is available at 3am on a bank holiday.
- Strengths: answers every call instantly; asks the same complete set of questions every time; can read and write to your booking system or CRM; cost per call is low and does not rise with peaks.
- Weaknesses: it can misunderstand unusual requests, it needs testing and tuning after launch, and some callers simply prefer a person.
- Best for: high volumes of routine calls, bookings, out-of-hours enquiries, and businesses that lose work to missed calls.
Side by side
- Answers instantly at any volume: AI yes; answering service mostly; voicemail no.
- Books into your own system: AI yes, with an integration; answering service sometimes, into a shared diary; voicemail no.
- Handles an upset or vulnerable caller well: answering service best; AI should hand over; voicemail no.
- Cost as calls increase: AI low and per minute; answering service rises per call; voicemail free.
- Complete, consistent details every time: AI yes; answering service usually; voicemail rarely.
The combination that works best
For most growing businesses the strongest set-up is layered. The AI receptionist answers every call first and handles the routine ones completely. Anything sensitive, complex, or outside its scope is transferred to a person, either your own team or an answering service, with a written summary so the caller does not start again. Voicemail becomes the last resort rather than the default.
That keeps the human time for the calls that need it, which is where both the cost and the quality of an answering service are best spent.
How to choose
- 01Count your missed calls for a fortnight, and note when they happen.
- 02Sort a sample of calls into routine (bookings, hours, prices, status) and sensitive (complaints, distress, complex advice).
- 03If most are routine, start with an AI receptionist and a handover rule for the rest.
- 04If most are sensitive and volumes are low, a human answering service is likely the better fit.
- 05If you already use an answering service, put an AI first line in front of it and compare the bill after a month.
We build AI receptionists that hand over properly, to your team or your existing answering service. If a human service on its own is the better answer for your calls, we will tell you.
