Business Phones · 3CX, VoIP & Yealink
We design, install and support 3CX phone systems and VoIP for small businesses across south-east Melbourne. Keep your numbers, answer from a desk phone, laptop or mobile, and deal with one local team in Narre Warren.
What We Do
Old copper lines and ageing phone systems are being switched off across Australia. A modern VoIP system gives you more features and far more flexibility.
A full-featured business PBX, hosted in the cloud or on your premises, configured around how your team actually works.
Keep the numbers your customers already know. We manage the move from your current provider.
A professional greeting and “press 1 for sales” menus that send callers to the right person first time.
Share incoming calls across your team so customers are answered quickly, even at busy times.
Yealink handsets, cordless phones and headsets supplied, configured and installed.
Make and receive calls on your business number from a mobile or laptop, in the office or on the road.
Voicemail messages delivered straight to your inbox, so nothing is missed after hours.
New starters, menu changes, after-hours messages and troubleshooting handled by a local team.
Switching Over
We run the new system alongside the old one until everything is tested, so your business is never off the air.
We look at your current phones, numbers, call flow and internet connection.
A clear plan for menus, queues, extensions and handsets, with a quote.
The system is set up and tested before a single customer call touches it.
Handsets installed, apps set up on mobiles and your numbers ported across.
We show your team how it works and stay on for changes and support.
Why Quantum
Most VoIP complaints, such as choppy audio, dropped calls and one-way sound, are network problems, not phone problems. A phone company will blame your internet. Your internet provider will blame the phones.
We look after the whole chain: router, WiFi, switches, internet and the phone system itself. As your managed IT provider, we find the real cause and fix it.
Using Microsoft Teams? We can connect your phone system with Microsoft 365 as well.
Tell us how many staff and lines you have and we will recommend the right setup, with no obligation.
FAQs
In most cases, yes. Landline, 1300 and 1800 numbers can usually be ported across to the new system. We check your numbers before you commit and manage the porting so there is no gap in service.
Not always. Many businesses use a mix of Yealink desk phones for reception and desks, plus the 3CX app on mobiles and computers for everyone else. If your current handsets are compatible, we can often reuse them.
Calls can be set to divert automatically to mobiles if your office connection drops, so customers still get through. For sites that rely heavily on phones, we can add a backup internet connection.
Yes. With the 3CX app, staff make and receive calls on the business number from a mobile or laptop anywhere, without giving out a personal number.
Most NBN business and home connections handle VoIP comfortably. We test your connection and network first, and fix WiFi or router issues that would affect call quality before you go live.
A typical small office is set up and tested within a few days. Number porting is handled by the carriers and usually takes longer, so we run the new system alongside the old one until your numbers move across.
