Running a small business in Australia without a decent phone system in 2026 is expensive. The average Aussie SME spends between $80–$150 per user per month on traditional phone lines — before international calls even enter the picture. This article covers the best VoIP options for Australian small businesses right now, what they actually cost, how local virtual numbers work, and which provider makes the most sense depending on how your team operates.
Key Takeaways:
- Australian SMEs can cut phone costs by 60–80% switching from traditional landlines to VoIP in 2026
- Browser-based VoIP like GlobCall lets unlimited team members share one balance with no per-seat fees — a major advantage over legacy systems
- International calls to Australian landlines run as low as $0.05/min from overseas, making local virtual numbers a practical tool for businesses with global clients

Why Australian Small Businesses Are Dropping Traditional Phone Lines
Traditional PSTN lines through Telstra or Optus cost $50–$100 per handset per month, lock you into hardware, and charge separately for international calls. VoIP costs a fraction of that, works from any device with internet, and scales with you rather than against you. Based on industry estimates, the majority of Australian SMEs with remote or hybrid teams have moved across since 2022.
The NBN rollout helped accelerate this. Once broadband became the standard backbone for Australian homes and offices, the business case for keeping copper-line phones collapsed. You're already paying for internet — VoIP just runs on top of it.
There's also the staffing reality. Small businesses often have 2–10 people: some in-office, some remote, maybe some overseas. A per-seat phone system charges for every single one of them, and that adds up fast.
What Actually Counts as VoIP in 2026?
VoIP — Voice over Internet Protocol — means any call routed through the internet rather than a physical phone line. The category has split into several distinct types, and they're not all equal for business use.
App-based VoIP includes services like WhatsApp, Viber, and similar consumer apps. Free between users, but you can't call regular phone numbers without credits, and they're not built for business workflows.
Hosted PBX / cloud phone systems are purpose-built for business. Think RingCentral, Vonage, or similar platforms. They give you call routing, extensions, IVR menus, CRM integrations — the works. They also come with per-seat fees starting around $25–$45 USD per user per month.
Browser-based VoIP is the newest category. No app to download, no hardware, no SIM. You open a browser tab and call any phone number in the world. GlobCall sits in this space — designed for teams that want low per-minute rates, a shared balance across the whole team, and zero seat fees.
The right answer for most Australian SMEs in 2026 depends on call volume, team size, and whether you need inbound infrastructure or just outbound calling capability.
The Best VoIP Options for Australian Small Businesses in 2026
1. GlobCall — Best for Teams That Call Internationally
GlobCall is a browser-based VoIP service with no per-seat pricing. Your whole team shares one balance, and anyone can make calls from any browser. Calls to Australian landlines cost $0.05/min — competitive for an international rate, and useful if your team is distributed globally and needs to reach Australian numbers regularly.
For Australian businesses calling overseas, the rates matter. Calls to the USA and Canada run $0.02/min. UK landlines are $0.03/min. India is $0.08/min. If your business deals with suppliers or clients across multiple countries, that's meaningfully cheaper than carrier add-ons.
You can also get virtual Australian phone numbers so international clients see a local number when you call — or can reach you on a familiar Australian number even if you're working from Bali or Bangkok.
No seat fees matters more than it sounds. A 6-person team on a $35/seat hosted PBX pays $210/month before making a single call. GlobCall charges only for actual call minutes used, shared across everyone. For small teams with moderate call volume, the saving is real.
The trade-off: GlobCall doesn't include a full PBX suite. No IVR trees, no call queues, no native CRM integration. For a 3-person consultancy that makes outbound calls and wants a professional inbound number, it's excellent. For a 10-person sales team that needs ring groups and call recording, you'll want something more structured.

2. RingCentral — Best Full-Featured Cloud PBX
RingCentral is one of the most widely used cloud phone systems globally, with solid Australian presence. Plans start around AUD $35–$60 per user per month for the Core tier, with higher tiers adding analytics, call recording, and video conferencing.
You get a proper PBX setup: auto-attendant, call routing, voicemail-to-email, team messaging, and integrations with Salesforce, HubSpot, Zendesk, and dozens more. If your business runs on a CRM and you want calls logged automatically, RingCentral delivers that.
The downside is the seat-based model. Part-time staff or occasional callers still cost full price per seat. The per-seat pricing problem hits small businesses harder than large ones.
International call rates through RingCentral can also add up. Their unlimited plans cover selected countries, but many destinations are charged per-minute on top of the subscription. Read the fine print before assuming "unlimited" covers your actual call destinations.
3. Vonage Business — Best for API and Developer-Friendly Teams
Vonage Business (now part of Ericsson) is a strong option if your team has technical resources and wants to build custom calling workflows. Their API lets you embed calling directly into apps or CRMs, automate outbound dialling, and build IVR flows without relying on a GUI.
For pure small business use without developer support, Vonage is probably overkill. But for a tech-forward SME — a SaaS company, a fintech startup, anything where calling is embedded in a product — Vonage's programmable voice is powerful. Pricing starts around $19.99 USD per line per month for the mobile plan.
Check the Vonage alternatives overview if you want to compare it directly against other options before deciding.
4. Microsoft Teams Phone — Best If You're Already on Microsoft 365
With Skype sunset in May 2025 and users migrated to Microsoft Teams, Teams Phone has become a natural fit for businesses already in the Microsoft ecosystem. If your team uses Outlook, SharePoint, and Teams for collaboration, adding Teams Phone gives you one unified workspace for calls and messaging.
Teams Phone requires a Microsoft 365 Business subscription plus a Teams Phone licence (around $8–$10 USD per user per month). You'll also need a Calling Plan or Direct Routing setup to connect to the PSTN — either buying minutes through Microsoft or routing through a third-party carrier.
The Teams Phone cost breakdown is worth reading before you commit. Total cost with all add-ons can surprise you — it's often more expensive than the plan-level price suggests.
5. Freshdesk / Freshcaller — Best for Customer Support Teams
If your small business runs any kind of customer support operation — helpdesk, bookings, after-sales — Freshcaller is worth a look. It integrates natively with Freshdesk and gives you a clean call centre setup with queues, IVR, and call routing without the enterprise price tag.
A free tier is available, with paid plans from $15 USD per agent per month. Australian numbers are supported. Freshcaller is specifically designed for inbound support workflows, so if your primary use case is receiving customer calls rather than making outbound ones, it fits well.
6. Aircall — Best for Sales Teams
Aircall is built for sales and support teams that live in their CRM. Deep integrations with HubSpot, Salesforce, Pipedrive, and Intercom. Real-time call coaching, call whispering, and analytics dashboards. Plans start at $30 USD per user per month with a minimum of 3 users.
It's polished. But you're paying for features a 2-person business won't use. If you have a sales team of 5+ making structured outbound calls and tracking pipeline, Aircall's analytics justify the cost. Under that threshold, you're overpaying for the integrations.
7. MyNetFone / Aussie Broadband — Best for Australia-Only Operations
For businesses that primarily operate within Australia — no international calling, local team, fixed office or home office — Australian-specific providers like MyNetFone or Aussie Broadband VoIP are worth considering. They're designed for the Australian network, priced in AUD, and offer local number porting.
MyNetFone plans start from around $20–$30 AUD per month per line and include a local or 1300 number. Support is Australian-based. For a café, a trades business, or any SME that simply needs a local business number to replace their landline, this is the most friction-free option.
The limitation is clear. The moment you need to call internationally or support a team member working overseas, local-only providers leave gaps.
How Virtual Australian Phone Numbers Work (And Why You Might Need One)
A virtual Australian phone number is a regular-looking 02, 03, 07, or 08 number — or a 1300/1800 — that's not tied to a physical location or SIM card. Calls to that number route to wherever you set them: your mobile, your VoIP app, your team's shared browser interface.
A few scenarios come up constantly for small businesses.
You're running a business but working remotely — overseas, interstate, or from home. A local number makes you look established to clients and avoids them seeing a mobile number they might distrust for business contact.
Your clients are in Australia but your team is partly offshore. A Sydney 02 number means clients aren't second-guessing who they're calling.
You're an international business wanting an Australian presence without a physical office. A virtual number gives customers a local contact point without the cost of local infrastructure.
GlobCall offers virtual numbers in 100+ countries. The setup guide for virtual business numbers in Australia walks through costs and configuration in detail if you want specifics.
Research consistently shows that a local phone number increases contact rates compared to a mobile-only contact page — the full explanation of why phone numbers affect website inquiries is worth reading if you're weighing whether to publish a number at all.
Pay-As-You-Go vs Monthly Subscription: Which Model Suits Australian SMBs?
This is the question most small business owners don't ask until they've wasted six months on the wrong plan.
Monthly subscriptions make sense when your call volume is high and predictable. If your team makes 2,000+ minutes of calls per month per user, a flat-rate plan often works out cheaper. You know your cost upfront and budgeting is straightforward.
Pay-as-you-go works better when call volume varies, your team size fluctuates, or you have staff who rarely make calls. You pay for what you use, with no wasted spend on idle seats.
For most Australian small businesses with under 10 people, pay-as-you-go VoIP wins — particularly for international calls. A team with 4 people where 2 make lots of calls and 2 make almost none will overpay every month on a per-seat plan. Shared balance models solve this directly.
There's a thorough breakdown of pay-as-you-go vs monthly subscription business phone options if you want to run the numbers for your specific situation.
What to Look for When Choosing VoIP in Australia
Don't get distracted by feature lists. Most small businesses use maybe 20% of what full-featured platforms offer. Focus on what actually determines day-to-day cost and reliability.
Call quality on Australian networks. Not all VoIP services perform equally on Australian broadband, particularly on regional connections or satellite internet. If you're on Starlink, VoIP performance on satellite connections is different from fibre — jitter and latency matter more than raw bandwidth.
Total cost of ownership, not advertised price. Add up the monthly subscription, per-minute rates for your actual call destinations, number hosting fees, and any add-ons you'll need. Compare that total across providers rather than headline prices.
Inbound vs outbound capability. Some services are primarily outbound (browser-based VoIP, calling apps). Others are primarily inbound (support platforms). A few handle both well. Know which you need before you start comparing.
Number portability. Can you bring your existing business number to the new provider? Most reputable VoIP providers support Australian number porting, but confirm before signing anything.
Contract terms. Month-to-month flexibility is worth paying a small premium for, especially if you're testing a new system. Lock-in contracts with small businesses rarely end well when circumstances change.

Frequently Asked Questions
Can I keep my existing Australian phone number if I switch to VoIP?
Most VoIP providers support number porting for Australian geographic numbers (02, 03, 07, 08) and 1300 numbers. The process typically takes 5–15 business days and requires your current provider's account details. Confirm porting availability with your new VoIP provider before cancelling your existing service — some rural or regional numbers have complications.
Is VoIP reliable enough for business calls in Australia in 2026?
Yes, for the vast majority of Australian businesses. On NBN 25 or above, VoIP call quality is consistently good. Issues tend to arise on congested connections or older NBN technology types like FTTN. A wired ethernet connection improves stability noticeably over WiFi. If you're on satellite internet, check provider-specific guidance for VoIP on Starlink.
Do I need special hardware to use VoIP for my business?
No. Browser-based VoIP like GlobCall requires only a computer, headset, and internet connection. Hosted PBX platforms like RingCentral can use softphones on existing devices. Physical VoIP desk phones are optional and mostly chosen for comfort in fixed-office environments. Most Australian SMEs in 2026 run entirely on laptops and headsets.
What's the cheapest way to call Australian numbers from overseas?
Calls to Australian landlines through GlobCall run $0.05/min — one of the lower rates available. Australian mobile numbers typically cost more, between $0.10–$0.25/min depending on the service. Check the full rates page for a complete breakdown. For context on how international calling rates are calculated, the international calling rates explained page covers the mechanics.
How many team members can share one VoIP account?
It depends entirely on the provider model. Per-seat systems charge per user regardless of usage. GlobCall's shared balance model for business allows unlimited team members on one account — you pay for actual call minutes, not headcount. For a small team where some people call frequently and others rarely, shared balance consistently costs less than per-seat pricing.
Wrapping Up
Australian small businesses have more phone system options in 2026 than ever, and more ways to overpay if you pick the wrong model for your situation. Here's what matters most:
- Traditional landlines are hard to justify. NBN infrastructure means you're already paying for internet. VoIP runs on top of that at a fraction of the cost of PSTN lines.
- Per-seat pricing hurts small teams. If half your team rarely makes calls, you're subsidising empty seats every month. Shared balance models fix this.
- Full-featured PBX isn't always necessary. If you need outbound calls and a professional inbound number, you don't need IVR trees and CRM integrations — and you shouldn't pay for them.
- Virtual Australian numbers work for remote and distributed teams. Local numbers build trust with Australian clients regardless of where your team is physically located.
- International rates vary enough to matter. If you call the USA, UK, India, or other markets regularly, per-minute rates compound quickly across a team.
The right system depends on your call volume, team structure, and whether you need inbound infrastructure or primarily make outbound calls. Start by testing actual call quality to your most-used destinations.
