AI receptionist versus a traditional answering service
Both answer your phone when you cannot. The difference is what happens next, and how the bill behaves when you get busy.

A traditional answering service is a team of people in a contact centre answering under your business name. An AI receptionist is software doing the same job. Both solve the same first problem, which is that your phone is ringing and nobody is picking it up.
They diverge on three things that matter: what happens when calls arrive together, what the service can actually complete, and how the price responds to volume.
Capacity, which is the real difference
A human answering service staffs for expected volume. When your calls spike, and spikes are exactly when this matters, callers queue. Ask any provider what their answer time looks like in their busiest hour rather than on average.
Software answers every call at the same instant. Fifty simultaneous calls is not a harder problem than one. For a taxi firm on a Saturday night, a heating engineer during the first frost, or an accountant in late January, this is the whole argument.
What each can complete without you
Most traditional services take a message and send it on. Better ones will book into a diary if you give them access, and the best operate as a genuine extension of your team, which costs accordingly.
An AI receptionist is generally built to complete the task: answer the question from your own information, book into the calendar, take the details and send you the transcript. The gap is narrowing from both directions, but a message is not a booking, and a booking is the thing that makes money.
Easier to hear than to read about
Callwise answers your phone the way this article describes. Ring it, ask it something awkward, and see whether it holds up.

A person can handle the call that does not fit any script, and will notice that a caller is upset before they say so. That is real and worth paying for on the calls that need it.
Software never has an off day, never forgets a qualifying question and writes down everything. On the eighty per cent of calls that are routine, consistency beats judgement. On the other twenty per cent it does not.
Cost behaviour
Human services are priced per call or per minute because their costs are per call or per minute. That model is honest but it means your bill rises with your success, and out of hours often carries a premium.
AI services are increasingly flat monthly, because the marginal cost of another call is near zero. For a business with volatile volume this converts an unpredictable cost into a fixed one.
How to choose
If your call volume is low, steady, and your calls are long and unusual, a human service is a reasonable choice and may be the better one.
If your volume spikes, if calls arrive together, if most of them are routine bookings and questions, or if you need genuine round the clock cover without a surcharge, the software case is strong.
Whichever you pick, ring their own line before signing. Both kinds of provider can be tested in ninety seconds by becoming a customer.
Questions people ask
Can I use both?
Yes, and it is a sensible pattern. Software answers everything, handles the routine, and escalates defined call types to a human team so people are reserved for the calls that need them.
Do callers know the difference?
A good assistant says it is an assistant. Most callers care far more about being answered immediately and getting booked than about who did it.

AI receptionist versus a human receptionist
These are not the same product and pretending otherwise helps nobody. One of them greets people at the door and knows your customers by name. The other one works at three in the morning.
Switching from an answering service
The switch itself takes about a day. The contract you are already in is usually the thing that takes three months.
What UK call answering services really cost
Published rates and final invoices are rarely the same number in this industry, and the gap is almost always in how time is rounded.
Hear it answer a call
Ring the assistant and ask it the awkward question your customers always ask. If you like what you hear, it will book you in there and then.
