About Call Sure: Why we built Call Sure.
Built out of a real need, by people who have spent decades building business software.
Our own line runs on Call Sure
Business API's own calls, answered and put through by the same service you can try.
Our story
Answering the phone was the part I could never get right.
I'm Andrew. I started my first company 25 years ago, and today I run Business API. For years, answering the phone was the part of the business I could never get right.
First I looked for a good receptionist. Good ones are hard to find and harder to keep, and we had too many calls to ignore but not enough to keep someone busy all day.
Then I tried answering services. They answered, but they couldn't get across the technical side of what we do. Explaining the technical side of our work to a call centre, and getting back a message that made sense, was a constant struggle. Important calls became vague notes, and the calls I did need to take came through cold, with no idea who was on the line.
What I wanted was simple: something that answers every call properly, understands the business well enough to ask the right questions, and only rings me when it's worth it. And when it does, it tells me who it is and why before I decide to pick up. We wanted to decide before picking up, so we built it.
Call Sure runs our own phone line first. Every feature exists because we needed it ourselves.

Business API's own phone line is answered by Call Sure, the same service you can try today.
What we care about
The same team, the same standards.
Call Sure is built and run by the team behind Business API, with the same standards.
Calls answered properly
A real conversation, not a phone tree. Callers are greeted properly, asked the right questions and never left on hold.
You decide who gets through
Your phone rings once and you hear who is calling and why before you pick up. Take it, or have a message taken.
Security and privacy first
Encrypted in transit and at rest with industry-standard encryption (TLS and AES-256), two-step sign-in for every client account, call records stored in Australia, and callers' data never used to train AI.
Built in Australia
Based in Southport, Queensland, building for Australian businesses.
