Everything a business phone should do, built in
3CX is a complete phone and communications system. Every feature below is included as standard, with nothing extra to buy.
Hosted on AWS
Your phone system runs in Amazon’s secure cloud, not a box in the cupboard. Prefer it on site? 3CX runs on premise too.
Your desk phone in your pocket
iPhone and Android apps ring with your business number, so you can take calls from the car, the job or home.
Web conferencing included
Video meetings, screen sharing and instant messaging are built in. No extra subscriptions.
Voicemail and fax to email
Messages and faxes land in your inbox, so nothing is missed when you are away from the desk.
Works with Microsoft 365 and your CRM
Click to call from your contacts and see who is calling before you pick up.
Hot-desking and presence
Log in at any phone and see at a glance who is free, busy or on a call.

Cut the phone bill, not the service
Old phone systems charge for line rental, call costs and maintenance. With 3CX you pay one flat price per user, and calls within Australia are unlimited.

VoIP questions, answered
What is VoIP?
Voice over Internet Protocol. Your calls travel over your internet connection instead of old copper phone lines, which is cheaper and far more flexible.
Can I keep my business number?
Yes. We move your existing numbers across to the new system, so customers keep calling the same number.
Is it as reliable as a traditional phone line?
Yes, when it is set up properly on a good connection. We check your internet before we start, and calls can divert to mobiles automatically if your office connection drops.
Can I use my existing phones?
Often, yes. Many existing handsets can connect through an adapter. We will check yours in the free consultation, or you can move to new Yealink handsets on monthly repayments.
Can I use it on my mobile?
Yes. The 3CX app for iPhone and Android lets you make and take calls on your business number from anywhere.
What equipment do I need?
An internet connection and either a desk phone, a computer with a headset, or the mobile app. We supply and set up Yealink handsets if you want them.
How much does it cost?
$55 per user per month for 2 to 50 users, with unlimited calls within Australia and a SIP trunk for one site included. Additional SIP trunks are $50 per month.
