The telephone answering service that books the job, not just the message.
Callsy answers every call in one ring, books the appointment into your diary, and texts a confirmation. 24/7, out of hours, and when your line is busy. So you never lose another customer to an engaged tone or a voicemail.
What your telephone answering service does
Answers every call, 24/7
No hold music, no engaged tone, no missed calls. Callsy picks up on the first ring, day and night, so a caller never reaches your voicemail and rings a competitor instead.
Books into your diary
It reads your diary, offers real slots, and books the appointment on the call, then texts a confirmation. A message service can't do that.
Takes and passes on messages
For anything it doesn't handle directly, it captures a clean, structured message and sends it to you by SMS or email in seconds.
Qualifies and routes callers
It asks your questions, captures the details, and warm-transfers the calls that need a person straight through to you or your team.
Covers out of hours and overflow
Evenings, weekends, bank holidays, and the calls your team can't reach when the line is busy. The hours you lose the most calls are the hours Callsy works hardest.
Speaks in your business's voice
A custom greeting and answers trained on your business. Callers reach a helpful, professional agent, not a generic call centre reading a script.
The basics
What is a telephone answering service?
A telephone answering service answers your business calls when you can't, so a caller always reaches someone instead of an engaged tone or voicemail. Traditionally that means human operators who take a message and pass it on. An AI telephone answering service like Callsy goes further: it handles the call, books the appointment into your diary, and follows up by SMS, 24/7. The result is simple: every call gets answered and actioned, even the ones a busy team would miss.
A human answering service charges per call or per minute and hands you a message. Callsy costs a flat monthly fee, works 168 hours a week, and turns the call into a booked appointment before the caller hangs up. Most UK businesses use it for the calls they were already losing: out of hours, during the rush, and when the line is engaged.

Telephone answering service FAQ
What is a telephone answering service?+
A telephone answering service answers your business calls when you can't, so a caller always reaches someone instead of an engaged tone or voicemail. Traditionally it's a team of human operators who take a message and pass it on. Callsy is an AI telephone answering service: it answers 24/7, handles the call, books the appointment into your diary, and follows up by SMS, rather than just taking a message you have to ring back.
How is an AI answering service different from a traditional one?+
A traditional telephone answering service is human operators who answer and take a message, then you call the customer back. An AI answering service answers instantly, resolves the call itself, books into your diary, and confirms by text, without per-minute call-centre pricing or the callback delay. For out-of-hours and overflow especially, the AI books the job while a human service is still writing down a name.
Does it work out of hours and at weekends?+
Yes. Callsy answers evenings, weekends, and bank holidays with no extra staffing. Most businesses lose the majority of their missed calls outside 9-to-5, so out-of-hours cover is where a telephone answering service pays for itself fastest.
How much does a telephone answering service cost in the UK?+
Traditional UK answering services usually charge per call or per minute, so a busy month adds up quickly. Callsy is a flat monthly fee for round-the-clock cover, so a few booked jobs typically pay for the whole month. There's a free trial, and if it doesn't pay for itself in 30 days you don't pay.
Is it compliant with UK data and marketing rules?+
Yes. Callsy is EU-built and GDPR-compliant with data hosted in the EU, encrypted in transit and at rest, and it operates in line with UK PECR for calls and messages. It's upfront that it's a digital agent, in line with the EU AI Act's disclosure rule, and you control exactly what it can and can't say.
Will callers know it's an AI?+
Callsy speaks naturally and is upfront that it's a digital agent. Callers care far more about reaching someone who can actually help and book them in right now than about whether the helper is human. A fast, useful answer beats a voicemail every time.
