Why Kallin
24/7 AI Receptionist
Your AI receptionist answers every call, day or night, so you never miss a lead or sale.
Connect Top UK Providers
Bring numbers from BT, Sky, Virgin Media, Vodafone, O2, EE, Three, and more — or use a fresh Kallin number.
Full Customisable Dashboard
Customise voice prompts, welcome messages, call flows, and routing rules from one dashboard.
Human Handoff
Forward calls to a real human when needed — we can provide a secondary number for live transfers.
How Onboarding Works
Getting started with Kallin is simple. A dedicated onboarding agent sets your account up for you so you can go live quickly.1
Sign Up
Create your account at kallin.co.uk. It only takes a couple of minutes.
2
Meet Your Onboarding Agent
A Kallin onboarding agent will reach out and configure your account for you — including a default Kallin number assigned automatically, so you can start straight away.
3
Use Your Own Number (Optional)
Want to keep your existing number? Let your onboarding agent know and they’ll walk you through how to connect or port it across. You don’t have to — a fresh Kallin number works just as well.
4
Set Up Human Call Forwarding (Optional)
If you’d like the AI to forward certain calls to a real human, we can set this up and provide a secondary number for live transfers.
5
Go Live
Once your prompts, welcome messages, and routing are configured, you’re live — and Kallin starts answering every call, 24/7.
