What is VoIP?

VoIP, or Voice over Internet Protocol, is a practical phone technology that routes calls over the internet instead of the traditional copper telephone line.

So rather than paying for a separate phone network, your calls travel as data, much like email or video calls.

For Australian businesses, VoIP means lower call costs, more useful features, and a phone system that works just as well in the office as it does on the go.

It’s also a smart move away from legacy copper networks, especially as the NBN (National Broadband Network) becomes the standard for reliable connectivity across homes and businesses in Australia.

Our Diverse VoIP Phone Solutions in Australia

VoIP phone systems can be tailored to suit the way your SME works, not the other way around. At OSIT, we offer three VoIP options designed to support different business needs, so you can choose the set-up that makes the most sense for your team.

  • Cloud Hosted PBX

    Enjoy the benefits of enterprise-level calling without the expensive on-site equipment or monthly spend.

    Combine enterprise-grade functionality with flexibility, low cost, and easy management.

    Traditional phone systems tend to keep your team tied to the desk. A cloud-hosted PBX gives you a different way to work, letting your team make and receive calls from almost anywhere using desk phones, laptops, mobiles, or web apps.

    Cloud-hosted PBX is considered a flexible VoIP phone system in Australia. In fact, it’s become the ideal choice for modern SMEs with hybrid and remote teams.

    At Office Solutions IT, we do more than roll out VoIP phones. We work with you to build and maintain a business communications setup that fits your wider IT environment and manage the whole thing on your behalf. 

    Our cloud-hosted PBX services are powered by UCXpress and UCXcel, two platforms we trust to make business communications simpler for Aussie SMEs.

    UCXpress suits businesses that have more phone extensions than active daily callers. Rather than paying per seat, you pay for the call capacity you actually use. This is a cost-effective fit for teams where not everyone is on the phone at once.

    UCXcel brings cloud voice, video, chat, and collaboration together in one unified communications platform. Powered by Cisco Webex and used by 95% of Fortune 500 companies, it gives hybrid teams more than a phone system; it gives them a simpler way to stay connected and work together.

    Why you might want this:

    ✔️ Access to advanced phone system features

    ✔️ Flexible calling from desk phones, laptops, mobiles, or web apps

    ✔️ Reporting and analytics for call volume insights, missed calls, wait times, and team performance

    ✔️ Microsoft Teams integration to business phone system

    ✔️ Scalable as your team grows, with no cabling or technician visits

    ✔️ Fully managed by OSIT

    ✔️ Intelligent call routing, call queues, hunt groups, and automated greetings

  • Microsoft Teams Phone

    Unleash the full power of Microsoft Teams by integrating it into your business phone system.

    Never switch apps every time someone needs to make a call ever again.

    There’s more to Microsoft Teams than chat, channels, and video meetings.  When it’s connected to your phone system, your team can make and receive business calls directly in Teams using your existing business phone numbers.

    If that’s not the simplest way to modernise communications while getting more value from your existing Microsoft 365, I don’t know what is.

    That’s why at Office Solutions IT, your VoIP phones are designed to work within the bigger picture.

    As a Microsoft Solutions Partner, we bring together M365, Teams Phone, direct routing, networking, cyber security, cloud, and user adoption to build business communications that work where your people already work.

    Our Teams Phone service runs through UCTeams, a Microsoft-certified Direct Routing platform. We take care of the setup, number porting, and ongoing management, so your team can make and receive calls in Teams from day one.

    Why you might want this:

    ✔️ Consistent business phone experience for on-site, hybrid, and remote teams

    ✔️ One platform for calling, collaboration, and day-to-day communication

    ✔️ Better call handling to help reduce customer wait times

    ✔️ Track call activity, response times, call volumes, and communication performance

    ✔️ Make & receive calls through Teams using existing business phone numbers

    ✔️ Manage your business comms through the Microsoft ecosystem

    ✔️ Bring calls, meetings, messaging, and collaboration together on one platform

    ✔️ Managed end-to-end by a certified Microsoft Solutions Partner

  • Still on a Legacy PBX?

    Modernise your phone system without replacing existing infrastructure (that’s still doing its job).

    Set a middle ground between legacy telephony and a full VoIP phone system.

    If you’ve got an on-premises PBX that’s still doing its job, replacing everything from scratch isn’t always the smartest move. And to be honest, not every business is ready to move off their existing phone hardware entirely, and that's okay.

    With SIP Trunking, you can modernise your business communications without ripping out the phone system you’ve already invested in.

    SIP trunking is a simple way to enjoy the cost and flexibility benefits of VoIP phones while you plan your next step at your own pace.

    At Office Solutions IT, we work with the phone systems you already have.

    When you’re ready to move to a fully managed cloud phone system, we’re already familiar with your setup and can help make the transition straightforward. So if your legacy phone system isn’t ready to retire just yet, you can still get the flexibility and functionality of a modern VoIP setup without starting from square one.

    Not sure whether SIP trunking is the right fit? We’re happy to review your setup and give you a straight answer.

    Why you might want this:

    ✔️ Reduce call costs on your existing phone system without replacing it

    ✔️ A lower-disruption first step toward a full VoIP migration

    ✔️ Route calls to a modern VoIP network to reduce communication costs

    ✔️ Add extra channels and services without major infrastructure changes

    ✔️ Redirect calls to alternative numbers, mobiles, backup locations, or other offices

    ✔️ Incremental migration path to adopt VoIP while preserving your existing phone setup

    ✔️ Access DID numbers, number porting, Microsoft Teams integration, call forwarding, disaster recovery, and more

FAQs About Our VoIP Services in Australia

VoIP (Voice over Internet Protocol) is a phone system that routes calls via the internet instead of the traditional copper landline.

VoIP phone systems in Australia work by converting your voice into data packets, sending it over the internet, and converting it back into clear audio at the other end. The result is a phone system that’s more cost-effective than traditional telephony and better suited to the way modern businesses work.

And VoIP isn’t just limited to voice calls. It can also support video meetings, messaging, and CRM integrations, bringing your business communications together on one platform.

Australian businesses switch to VoIP providers for a few practical reasons. Here are the big ones:

  • Australia’s copper telephone network is being phased out and replaced with NBN.
  • VoIP phones significantly cost less than traditional phones
  • Your team enjoys the flexibility that VoIP phone systems offer
  • Easily scalable as your business grows, without needing a technician on site every time you add a user
  • Can be integrated with tools your team already uses, including Microsoft Teams and CRMs

Yes!

VoIP is a smart fit for small businesses looking to optimise their phone systems.

It eliminates expensive on-site PBX hardware and PSTN costs and is easily scalable. And it also lets you access features like auto-attendants and call queues without costing you an arm and a leg.

Absolutely!

The thing with having a VoIP phone system for your Australian SME is that your systems will have the capacity to deliver reliable and quality calls when it's set up properly.

And since phone systems rely on resilient cloud infrastructure, they also need a stable internet connection for optimum call quality.

That’s why OSIT looks at your network first and helps you choose the right VoIP setup for the way your business works. The result is clearer calls, better reliability, and a phone system that’s a big step up from traditional landlines.

At Office Solutions IT, we only provide purpose-built IT solutions.

Meaning, we only build IT solutions that you need.

We look at your systems and only recommend the right fit for the way your business works. And if your business scales, we can adjust your systems along with it.

The same goes for your business VoIP in Australia. What you need is what we'll implement, and we do it proactively.

No more, no less. Just enough.

VoIP service costs vary in Australia because the right setup depends on how many users you have, the features you need, and the pricing model that makes the most sense for your team.

At Office Solutions IT, we offer per-user, pay-as-you-go, and fixed-fee options, along with the assessment and setup needed to get everything working properly from day one. Whether you’ve got a team of under 10 or a few hundred people across the business, we can help you put the right phone system in place.

Reach out to us for a tailored business VoIP solution for your Australian SME today.

Definitely!

OSIT can port all your Australian phone numbers (standard landlines, mobile numbers, 1300 and 1800) into your shiny new VoIP system without disrupting incoming calls.

Yes! VoIP phones integrate pretty well with Microsoft Teams.

And if you want to turn Teams into a full business phone system, we can help with that too.

As a certified Microsoft Solutions Partner, Office Solutions IT can help assess, integrate, and maintain your Teams and VoIP phone system, so it works properly for your Australian SME from day one.

Yes, VoIP phones require reliable internet to work seamlessly.

Even the best VoIP setup in Australia will only perform as well as the network behind it. So if your internet is patchy, your business communications will be too.

Fortunately, at OSIT, we provide both: the right VoIP phone system and the reliable business internet to support it.

Enjoy the benefits of VoIP without the hassle

With Office Solutions IT, you can gain all the flexibility of modern phone systems without the cost blowouts or business disruption.
