VoIP for Small Business Australia: The Complete Setup Guide
A step-by-step guide for Australian small businesses on how to switch to a VoIP phone system, from choosing a provider to setting up your hardware.

Switching your small business to a VoIP (Voice over Internet Protocol) phone system is one of the most impactful upgrades you can make. It cuts costs, increases flexibility, and provides a suite of professional features that were once only available to large enterprises. This guide will walk you through the entire process, step-by-step, for a smooth transition.
Step 1: Assess Your Needs and Internet Connection
Before you start, take stock of your requirements:
How many users do you have? This will determine the number of licenses you need.
What features are essential? Do you need call recording, an auto-attendant (IVR), or CRM integration? Make a list of must-haves and nice-to-haves.
Do you want to keep your existing phone number? Most providers offer number porting.
Most importantly, check your internet connection. VoIP relies on a stable, high-quality internet connection. Run a speed test to check your upload and download speeds and latency (ping). For reliable call quality, a business-grade NBN connection is strongly recommended.
Step 2: Choose the Right VoIP Provider
Not all VoIP providers are created equal. Look for an Australian-based provider that offers:
Transparent Pricing: Clear per-user, per-month pricing with no hidden fees. Check what's included in the monthly fee (e.g., standard calls, support).
Local Support: Having access to an Australian support team who understands the local market is invaluable.
Scalability: Choose a provider that makes it easy to add or remove users as your business grows or changes.
A Strong Feature Set: Ensure the provider offers the features you identified in Step 1. A provider like Click2Call includes advanced features like AI-powered transcription and an AI Receptionist even in affordable plans.
Step 3: Select Your Hardware (or Go App-Only)
One of the biggest benefits of VoIP is that you don't necessarily need traditional desk phones.
Softphones (Apps): Most providers offer free desktop and mobile apps that turn your computer or smartphone into a fully-featured business phone. This is the most flexible and cost-effective option, perfect for remote teams.
VoIP Desk Phones: If you prefer a physical handset, you'll need to purchase VoIP-compatible phones. Brands like Yealink and Grandstream are popular choices. Your provider can usually supply pre-configured phones for a plug-and-play experience.
Headsets: A good quality USB or Bluetooth headset is essential for clear, hands-free communication, especially when using softphones.
Step 4: The Onboarding and Porting Process
Once you've signed up with a provider, the setup process begins:
Configuration: Your provider will work with you to configure your system. This includes setting up your auto-attendant ("Press 1 for Sales..."), voicemail, call groups, and business hours.
Number Porting: You will need to sign a Porting Authority Form (PAF) to give your new provider permission to move your phone number from your old carrier. This process is managed entirely by the provider and can take 5-30 business days. Do not cancel your old service until porting is complete.
Hardware Delivery: If you ordered desk phones, they will be shipped to you.
Step 5: Go-Live and Training
On the scheduled "go-live" day, your number will be active on the new system. Here’s what to do:
Plug in your phones: If you have desk phones, simply plug them into your office network. They should automatically connect to the system.
Install the apps: Download the softphone apps onto your computers and mobiles and log in with the credentials provided.
Test everything: Make some inbound and outbound calls to ensure everything is working as expected.
Train your team: While modern VoIP systems are intuitive, a quick training session on how to use the new features (like call transfer, conferencing, and checking voicemail) will ensure a smooth adoption.
Conclusion
Making the switch to VoIP is a straightforward process that delivers immediate benefits for Australian small businesses. By choosing a reputable local provider and following these steps, you can unlock a more powerful, professional, and cost-effective communication system that will grow with your business.
Frequently Asked Questions
Absolutely. You can port your existing 1300 or 1800 number to your VoIP provider, or they can supply you with a new one. All incoming calls to your toll-free number will be routed through your new VoIP system.
This is a key advantage of VoIP. If your office internet fails, your provider can automatically forward all incoming calls to a designated backup number, such as a mobile phone. This ensures you never miss a customer call, even during an outage.
