Kallorix or the BT AI Receptionist?

The short version

BT's AI Receptionist is a general virtual assistant for businesses of many kinds, sold by the minute through BT Business and, according to BT's page, built on RingCentral. Kallorix is an AI receptionist built specifically for UK trades, with published flat prices.

What we say about the BT AI Receptionist comes from business.bt.com as it read on 11 October 2026. Products and prices change, so check their site for the current details. If anything here is out of date, email us and we will correct it.

What the BT AI Receptionist offers

According to BT Business's website, it is a virtual assistant that answers incoming calls around the clock. It can handle bookings, capture enquiries and pass calls to a person when needed.

• Set up in minutes and trained on your website, your frequently asked questions or documents you upload
• Handles several calls at once, with personalised greetings
• Can run all day and night or match your opening hours
• Triages calls to the relevant person
• Usage shown in a customer portal

The examples on BT's page include a dog grooming salon, a car dealership, a bike shop and a deli.

What Kallorix offers

Kallorix answers the calls you miss as your business, asks the questions your trade needs and texts you the job.

• Built from your website in about two minutes; you check it before she takes a call.
• Question sets for sixteen trades, each kept short.
• A job text straight after the call: name, number, where, what, how soon.
• A link texted to the caller to share a location or a photo.
• An urgent caller tried on your mobile once; a free time offered from your calendar.
• Works with any UK network. If yours can't divert, your Kallorix number rings your mobile first.

How each is priced

BT's page does not show monthly prices. It says minutes are sold in bundles of 100, from 100 up to 14,000 a month, and that the service is billed on inbound minutes. Administrators are emailed at 80% and 100% of usage. At 100% the service switches off unless more minutes are bought or overage is enabled; overage is off by default, is charged per minute at a higher rate, and can have a spending cap. The contract is monthly rolling.

BT also lists an optional one-hour education session at £150. Its page mentions a free demo that you book, and a promotional discount on its smaller packages that was running when we looked.

Kallorix publishes its prices:

• Starter: £39 a month, 250 minutes
• Growth: £99 a month, 500 minutes
• Maximus: £149 a month, unlimited minutes with a fair-use ceiling of 3,000

There are 7 days free and no contract. If your minutes run out, your phone still rings as normal. A caller you miss hears that you will ring back, and we text you their number, so the enquiry is not lost. We never charge for going over.

Why trades choose Kallorix

These are the differences that matter most to a trade business, set against what BT publishes about its own service.

• You can see the price. Ours is published. BT's page shows no monthly prices.
• Your calls don't stop at the limit. BT's page says that at 100% of your minutes the service turns off unless you buy more or enable overage at a higher rate. With Kallorix your phone still rings, the caller hears that you will ring back, and we text you their number. The enquiry is never lost, and you are never billed extra.
• Try it now, without booking a demo. Give us your website and ring your own receptionist in about two minutes. No card, no appointment with sales.
• No paid set-up session. BT lists an optional £150 education session. Ours is set up from your website, and we make changes for you on request.
• She asks what your trade needs. BT's examples are salons, shops and dealerships. Ours is built for the trades.
• The job by text, with a location pin or a photo from the caller when it helps.

Who the BT AI Receptionist suits

• Businesses that already buy their phones and broadband from BT Business and want one supplier.
• Organisations that prefer a large, established provider.
• Businesses with a team, where calls need directing to the right person or department.
• Shops, salons and offices that mainly take bookings and answer opening-hours questions.
• Larger organisations that need thousands of minutes a month.

Who Kallorix suits

• Sole traders and small trade firms who want to see the price before talking to anyone.
• Trades whose callers have an urgent job and need the right questions asked.
• Owners who want to hear their own receptionist first, without booking a demo.
• Businesses that want a missed caller's number even when the allowance has run out.
• Anyone on a network or tariff that can't divert calls.

A note on size

We are a small company and BT is a very large one. That cuts both ways. A large supplier offers a familiar name and a wide range of services. A small specialist can set up the particular thing your trade needs: when a recovery firm asked for calls to be handed to a named driver, we built it for them.

Neither is a reason on its own. What matters is how your calls are answered.

How to decide

If you want everything from one large supplier and your calls are mostly bookings and general questions, BT's product is a sensible fit. If you are a trade and the value of a call is in the details, try the specialist.

The honest test is to hear both. Build a free Kallorix demo from your own website, or from your trade and town if you have no site. It takes about two minutes and needs no card. Ring it as an awkward customer, read the text it sends you, and compare that with what you hear elsewhere. Choose whichever would win you the most jobs.
