We are CallTech, a Perth company that started life in 1992 as Telemanagement Australia and took the CallTech name in 2009, by which point recording and response work was most of the business. From the beginning we sold and serviced professional telephone headsets under the AAA Headsets name, and have never stopped. We hold headset stock locally in East Perth, and some of the customers buying from us today have been with us from the start.
Along the way we built a lot of custom telephony, from prepaid patient phone systems to call queuing, and ran Perth's biggest 1900 premium number service. None of that is the business today, but it is where we learned how phone systems actually behave, and why customers kept asking us to solve their next problem.
Active Response
In 2003, we were contacted by Perth Airport. In an emergency, they were manually notifying their staff using an Excel spreadsheet, making one phone call at a time. It took about half an hour to get through the list. We wrote them a system that sends an SMS to everyone on the roster, waits two minutes, and rings anyone who has not replied. Notification time dropped to under three minutes. The Perth Airport Response System (PARS) became Active Response. It is still used for every emergency by Perth Airport, and by Emirates across Australia and New Zealand.
On-Call Router
We built Western Power a custom on-call routing system in 2008. Keeping their roster of on-call numbers up to date was error prone. Someone off sick meant a new list for the call centre. So each on-call line was given a fixed phone number, which never changes. Whoever is on duty dials in with a PIN and sets themselves as the diversion for that line. After-hours calls reach the right person, any time, every time.
Recording
When customers started asking us to record calls, we chose Red Box. Its frame-based recording architecture meant less audio lost when something went wrong, and fewer support problems once systems were in.
Red Box is not the only recorder we supply. In 2025 we deployed an Eventide solution for Evolution Mining. Eventide's recorders are purpose-built Linux appliances made for round-the-clock dispatch and emergency call-taking, and is able to log radio metadata like alongside the audio. For a mining site running radio as its primary channel, it's a better fit. We commission and support what suits the site, rather than fitting every site to one product.
Where nothing on the market fits, we build it. In 2018 Codan came to us needing a recorder that could go out with a radio - no server, no network, no rack. We developed Voice Logger: a single channel, VOX-activated recorder based on Raspberry Pi, cheap enough to deploy per radio and completely standalone. That became Recordari, which we sell today for exactly that job. A 3.5mm lead into a handheld radio and you have a recording, at a price point no enterprise recorder reaches.
Today our recorders capture telephone calls and radio traffic for customers around the country and on two floating LNG facilities 200 km off the WA coast. These are the recordings that are required when something goes wrong: an emergency call, a radio exchange with an aircraft, an alarm on a platform. They have to be there, complete and intact, every time.
Who you'll deal with
CallTech is Scott and Steve. We own the company, we sell the systems, we install them, and we answer the phone when something breaks. Nearly all of that is done remotely from East Perth, which is how we look after sites across Australia. meet the team.
