What is a 24/7 AI receptionist and what does it do?

A 24/7 AI receptionist is a voice agent that answers your business calls around the clock, so no caller reaches a busy tone or voicemail. It books appointments, answers questions from a knowledge base you update in plain language, takes messages, and transfers genuine emergencies to a person when configured. Kalvo works across three channels: phone calls, a website chatbot, and email, with WhatsApp coming soon. It handles many calls at once, so ten people ringing at the same time all get answered without waiting. You decide how it runs: fully automatic, or in approval mode, where drafts wait for one-tap approval before anything goes out. Because the knowledge base is yours to edit, the answers stay accurate. Update your opening hours, prices, or services in plain sentences, and callers hear the current details straight away. There is no script to code and no phone tree to maintain.

What happens to calls at night and on weekends?

Calls at night, at weekends, and on public holidays are answered the same way as during office hours. Kalvo picks up on the first ring, helps the caller, books appointments, and takes messages. Nobody hits voicemail or a busy tone, so enquiries that used to vanish after hours are captured. This matters because around 62% of calls to small businesses go unanswered, and most of those callers do not ring back. They try the next name on the list. Every missed call outside staffed hours is a booking, a quote, or a new customer that quietly goes elsewhere. With Kalvo answering at all hours, that after-hours demand turns into booked appointments and clear messages waiting for you in the morning. You can run it fully automatic, so it acts on every call, or in approval mode, where any drafted reply waits for your one-tap approval before it is sent.

Can it reach a real person for a genuine emergency?

Yes. When you configure it, Kalvo transfers genuine emergencies to a real person straight away. You define what counts as urgent for your business, and the agent recognises those calls, then puts them through to the number you choose. Everything else is handled or taken as a message, so only true emergencies interrupt anyone. This keeps genuine urgent calls moving without waking you for routine questions. A burst pipe, a dental emergency, or a locked-out customer can reach a person, while appointment changes and general enquiries are dealt with quietly in the background. You stay in control of the rules. Set the transfer number, decide the hours it applies, and adjust what counts as an emergency whenever your needs change. If nobody is available to take a transferred call, Kalvo takes a detailed message instead, so the caller is never left with nothing and you have the details to follow up fast.

How does it go live on your existing number?

Kalvo works on the number you already use. You either point that number at Kalvo, so it answers every call, or set a divert that sends callers to Kalvo only when you do not pick up. Nothing changes for your customers, they ring the same number, and setup takes minutes. Pointing the number at Kalvo suits businesses that want every call answered by the agent first. A divert suits those who still take calls themselves and want cover only for the ones they miss, whether the line is busy, out of hours, or nobody is free. Once the number is connected, you fill the knowledge base with your hours, services, and common answers in plain language. From there Kalvo is live and answering. You can adjust the wording, transfer rules, and approval settings at any time, and changes take effect straight away without any technical work.

Common questions

How fast is setup?

Setup takes minutes. You connect your existing number, either by pointing it at Kalvo or setting a divert, then add your hours, services, and common answers to the knowledge base in plain language. Once that is in, Kalvo is live and answering calls. You can refine the wording and rules whenever you like.

Can I keep my existing number?

Yes. Kalvo runs on the number you already use, so your customers keep ringing the same one. You either point the number at Kalvo, so it answers every call, or add a divert that reaches Kalvo only when you do not pick up. There is no need to publish a new number.

Can it transfer urgent calls to a person?

Yes, when you set it up. You decide what counts as urgent, and Kalvo transfers those callers to a real person at the number you choose. Routine calls are handled or taken as messages, so only genuine emergencies interrupt anyone. If no one is free, Kalvo takes a detailed message instead.

What does it cost?

Kalvo has three monthly plans. Starter is £49 a month for 100 minutes, Growth is £99 a month for 400 minutes, and Pro is £199 a month for 1000 minutes. Every plan answers calls, the website chatbot, and email, books appointments, and takes messages. Pick the plan that fits your call volume.

How is my data handled under UK GDPR?

Your data is handled under UK GDPR. Call details, messages, and knowledge base content are used to run your receptionist and answer your callers, nothing more. You stay in control of what the agent knows and can update or remove it at any time from your dashboard.
