Best VOIP Provider for Small Business Australia (2026)

This guide compares the VOIP providers that actually serve Australian small businesses in 2026 -- covering real monthly pricing, NBN compatibility, support quality, and contract terms. Most small business owners don't need to know which handset to buy. What they need first is a provider: the company that supplies your phone number, routes your calls, manages your cloud PBX, and picks up the phone when something goes wrong. By the end of this guide, you'll know which AU-based and international providers are worth shortlisting, what separates them, and what questions to ask before you sign anything.

Top VOIP Providers for Australian Small Business

What Does a VOIP Provider Actually Cost in Australia?

Pricing for Australian VOIP providers breaks down into three components: the per-seat monthly plan fee, call costs (often included or capped), and optional add-ons like 1300 numbers, call recording, or CRM integrations. Here is what realistic budgeting looks like for a typical small business.For a 3-5 seat business taking mostly inbound calls, expect to pay between $75 and $150 per month all-inclusive at the entry level. That covers your hosted PBX, your phone numbers, voicemail-to-email, ring groups, and basic call routing. It does not cover handsets, which are a separate one-off cost (typically $80-$250 AUD per desk phone, check current prices from AU distributors).For a 10-15 seat operation with higher outbound call volume, a 1300 number, and call recording, realistic monthly spend is $350-$600 per month. Some providers bundle calls; others charge per minute. If your team makes many outbound calls, a bundled plan is almost always better value. If you are mostly inbound, a lower per-seat rate with pay-as-you-go calls can work well.International VOIP providers like 8x8, RingCentral, and GoTo Connect publish pricing in USD on their global sites. When you see '$30 USD/user/month', convert that to AUD and add GST. At the time of writing that is roughly $47-$50 AUD per user per month before any discounts. AU-based providers like Maxotel and net2phone price in AUD from the start, which removes the currency risk and makes budgeting simpler.

Provider-by-Provider Breakdown

Maxotel

Maxotel is an AU-based VOIP provider operating as a specialist for the SMB market. Their positioning is consultative -- they ask how your business works before recommending a plan, which makes them well-suited to businesses that haven't set up a proper phone system before. That includes a large share of the AU market, where many businesses are still running analog phones through the green port on their ISP modem without realising they have alternatives.Pricing starts at roughly $25/seat/month for a hosted PBX plan, with month-to-month contracts available. Their local AU support team handles full setup, handset configuration, and number porting -- services that larger international providers often charge extra for or hand off to resellers. For a 1-10 seat business that wants someone to walk them through the whole process, this is a genuinely strong option.Where Maxotel is less strong: advanced analytics dashboards, large-scale CRM integrations, and enterprise-tier call centre features. If your business has 30+ seats or needs deep Salesforce or HubSpot integration, the international players have more mature tooling in those areas.

8x8

8x8 is a US-headquartered provider with AU infrastructure and local support. Their platform is mature and full-featured: ring groups, auto-attendant, call queuing, voicemail-to-email, call recording, and an analytics dashboard that goes well beyond what most SMB providers offer. If you need to measure call volume by team, track missed call rates, or generate reports for management, 8x8 handles this well.Pricing in AU is roughly $35-$55 AUD/user/month depending on tier, billed annually. Month-to-month options exist but at a premium. One caution: the 8x8 admin interface is comprehensive but not simple. A non-technical business owner setting it up alone will find it more complex than a specialist AU provider. Factor in either IT support or onboarding assistance when budgeting.8x8 has AU data centre options, which matters for call latency and for businesses with data residency requirements. Their AU support team is responsive in business hours. International calling rates are competitive if your team makes regular calls to the US or UK.

RingCentral

RingCentral is one of the largest VOIP and unified communications platforms globally, and they operate in Australia with AU-based support. Their strength is breadth: phone calls, video meetings, team messaging, and fax (yes, still relevant in healthcare and legal) all in one platform. For businesses already invested in Microsoft 365 or Google Workspace, RingCentral integrates cleanly with both.Entry-level plans start around $35 AUD/user/month (annual billing), with mid-tier plans at $50-$65 AUD/user/month when you factor in AU pricing and GST. The admin portal is powerful but has a learning curve. For teams of 5-30 seats that have some IT support available or a tech-comfortable admin, RingCentral gives you room to grow without switching providers.The limitation for very small businesses: RingCentral is designed to sell to mid-market buyers. The onboarding experience assumes some technical comfort, and their support model favours self-service documentation over hand-holding. If you want someone to call and walk you through your first ring group setup, Maxotel or net2phone will give you a better experience at the 1-5 seat level.

net2phone

net2phone operates in Australia through a reseller network and is one of the more competitive options for cost-conscious SMBs. Entry plans include unlimited local calls, which suits businesses with high inbound volume where per-minute billing would add up. Starting pricing is around $20-$25 AUD/user/month for the base tier.The trade-off is that because net2phone operates through resellers in AU, support quality varies depending on who your reseller is. If you find a good reseller, it works well. If not, escalations can be slow. Ask your reseller explicitly: who do you call if the phones go down at 9am on a Monday? Get a direct answer before signing.net2phone suits businesses that want solid core VOIP features at a lower price point and have someone in-house (or a trusted IT person) who can handle basic troubleshooting without hand-holding. It is not the right fit if you need end-to-end setup support from the provider.

GoTo Connect

GoTo Connect (formerly Jive) is built for teams that want softphone-first operation -- meaning staff use an app on their computer or mobile rather than a physical desk phone. This suits remote or hybrid teams well, and businesses that have already moved away from physical handsets. GoTo Connect integrates with Microsoft Teams, which makes it a useful bridge for businesses that want Teams for internal communication but need a proper AU phone number and VOIP service for external calls.AU pricing is around $30-$45 AUD/user/month on annual plans. GoTo Connect has AU-based support and local number availability. Their dial plan editor (which controls how calls are routed) is visual and easier to use than most competitors -- a genuine usability advantage for non-technical admins setting up call flows.Where GoTo Connect is weaker: if you need physical handsets as the primary device, their ecosystem is slightly less polished than 8x8 or RingCentral. It works fine with Yealink and Grandstream phones, but the setup experience is more hands-on than a managed provider like Maxotel.

Vonage Business

Vonage Business (now part of Ericsson) has strong AU presence and a well-regarded API platform (Vonage Communications APIs, formerly Nexmo) for developers. If your business needs custom call routing, click-to-call from a CRM, or programmatic SMS alongside VOIP, Vonage's developer ecosystem is hard to beat.For most small businesses, the API depth is irrelevant. What matters is that Vonage's standard hosted PBX plans are competitive (roughly $30-$50 AUD/user/month) and their AU support has improved significantly in recent years. Annual contracts are the standard; month-to-month options exist but at meaningfully higher rates.Vonage is worth serious consideration if your business is growing quickly and you expect to integrate your phone system with CRM (Salesforce, HubSpot, Zoho) or customer service platforms in the next 12 months. The integration depth is genuinely excellent. If you are a 2-person trade business wanting to take calls more professionally, it's more than you need.

What Most Businesses Get Wrong When Choosing a VOIP Provider

Choosing a VOIP provider is not the same as choosing a phone. Most of the mistakes happen before the first call is made.

Mistake 1: Comparing providers on features, not on support model

Every provider in this guide can handle ring groups, voicemail, and auto-attendant. The features are not what separates them for a small business. What separates them is what happens when something breaks, when your number port goes wrong, or when a new staff member needs a phone set up in 30 minutes. A provider with slightly fewer features but genuinely responsive AU support is worth more to a 5-person business than a feature-rich platform with offshore script readers. Ask every provider you shortlist: 'What is your average response time for phone support, and where is that team based?'

Mistake 2: Assuming the ISP phone service is a real business VOIP service

Many Australian businesses are still running their phones through the green ATA port on their ISP-supplied modem. That port provides a single analog phone line -- no ring groups, no hold music, no after-hours routing, no way to transfer calls to a mobile. When two customers call simultaneously, the second gets an engaged tone and calls a competitor. This is not a VOIP business phone system. It is an analog phone using a digital connection. Switching to a proper VOIP provider fixes all of this, typically for less than $30 per seat per month. The cost of staying on the ISP ATA -- in lost leads and missed calls -- is almost certainly higher than the cost of upgrading. See our guide to VOIP vs traditional phone systems for the full breakdown.

Mistake 3: Signing a 24-month contract before testing call quality

Call quality on a VOIP service depends partly on the provider and partly on your NBN connection -- specifically your upload speed, latency, and jitter. A provider that works perfectly for a business on a Fibre to the Premises (FTTP) connection may have quality issues on an older Fibre to the Node (FTTN) service with marginal upload speeds. Most reputable providers offer a trial period or month-to-month onboarding. Use it. Test with real calls in your real office before committing to a 12 or 24-month contract. If a provider won't let you trial before committing to a long contract, that tells you something.

Key Factors When Choosing an Australian VOIP Provider

AU number availability and porting

Confirm the provider can supply a geographic number (02, 03, 07, 08) in your area, and that they can port your existing business number. Number porting in Australia typically takes 5-10 business days under ACMA regulations, though some providers have faster processes. Do not assume the port will be instant -- plan for it, and maintain your old service until the port is complete and tested. Losing a business phone number mid-port because the timeline wasn't planned is a common and preventable problem. See our NBN VOIP setup guide for porting steps and what to check with your provider upfront.

NBN compatibility and call quality track record

Not all VOIP providers handle NBN variability equally well. A provider with AU-based SIP infrastructure (AU data centres, AU peering) will generally deliver lower latency and better jitter performance than a provider routing calls through US or Singapore infrastructure. Ask each provider where their AU SIP servers are located. For businesses on FTTP or HFC, this matters less. For businesses on FTTN with marginal upload speeds (anything under 5Mbps upload), AU-hosted infrastructure can meaningfully reduce call quality issues. For a detailed technical breakdown of VOIP call quality factors on NBN, see our VOIP call quality guide.

1300 and 1800 number support

If you want a 1300 or 1800 number for your business, confirm your provider can supply and manage it. Not all VOIP providers offer this directly -- some require a separate number broker. Most of the providers in this guide support 1300 number supply and routing, but pricing and management interfaces vary. For businesses where a 1300 number is part of the brand (tradies, health clinics, professional services), get this confirmed in writing before you commit to a provider. See our 1300 number guide for what to expect on costs and regulations.

Contract terms and exit conditions

Australian Consumer Law gives businesses some protection on service contracts, but it does not eliminate lock-in costs on hardware or setup fees. Read the cancellation terms before you sign. Specifically: What is the notice period? Are there early exit fees? What happens to your number if you leave -- can you port it to a new provider? A reputable provider will give you straightforward answers to all three. If answers are vague or buried in a 40-page PDS, factor that into your decision. Month-to-month contracts cost slightly more per seat but give you the flexibility to switch without penalty if the service doesn't meet expectations.

Handset and hardware support

This article is about choosing a provider, not a phone. But the two decisions interact. Some providers ship pre-configured handsets direct to your business -- you plug in, you're live. Others provide configuration guides and leave setup to you. For non-technical teams, provider-supplied pre-configured phones save real time. Ask whether handsets are included in the plan or purchased separately, whether the provider will pre-configure them to your account, and whether they support the handset brands you already own. For handset recommendations, see our best SIP desk phone guide.

AU-Specific Considerations for VOIP Providers

The PSTN shutdown and what it means for your provider choice

Australia's copper PSTN network was progressively decommissioned as the NBN rolled out, with the process largely complete by 2025. If your business is still on a legacy copper landline through Telstra, your service may already be on borrowed time. Moving to a VOIP provider is no longer a tech upgrade for most businesses -- it is the default path. The question is which provider to move to, not whether to move. Any provider you choose should have a clear NBN compatibility statement and experience migrating businesses from copper or ISP-ATA setups. For more on the NBN's impact on VOIP, see our NBN VOIP compatibility guide.

000 emergency calling on VOIP

VOIP providers in Australia are required to provide access to 000 emergency services, but there are important differences from traditional phone lines. VOIP 000 calls require your service address to be registered with the provider -- if you change offices or have mobile users working from different locations, your registered address may not match your actual location in an emergency. Confirm with your provider how they handle 000 registration, particularly for remote workers. This is an ACMA regulatory requirement, and any reputable AU provider will have a documented process for it.

Power outages and NBN VOIP

When power goes out, NBN goes out -- and VOIP goes out with it. This is a meaningful difference from traditional copper phone lines, which drew power from the network and kept working during power cuts. If your business needs to remain reachable during power outages (medical clinics, emergency services, essential trades), you need a plan. Options include battery backup units for your NBN equipment and router, a mobile number as failover in your VOIP auto-attendant, or a 4G SIM-based backup connection. Ask your VOIP provider what failover options they support and how quickly your call routing can be switched to a mobile number in an emergency.

Number porting timelines under ACMA rules

Under ACMA's Local Number Portability (LNP) rules, geographic numbers (02, 03, 07, 08 area codes) must be ported within 2 business days of a completed request, though in practice most SMB ports take 5-10 business days when factoring in verification steps and provider processing times. Freephone numbers (1800) and local rate numbers (1300) have different processes and may take longer. During the port window, both your old and new service may have periods of reduced capability -- plan for this, communicate with your team, and keep a mobile number available as a fallback. Never cancel your old service before confirming the port is complete and tested.

SIP ALG: the hidden NBN call quality killer

SIP ALG (Application Layer Gateway) is a feature built into many routers and NBN modems that attempts to help VOIP calls pass through NAT -- but in practice it causes more problems than it solves. Symptoms include one-way audio (you can hear the caller but they can't hear you), calls dropping after exactly 30 seconds, or registration failures on your VOIP handsets. If you experience any of these issues after switching to a new VOIP provider, the first troubleshooting step is to disable SIP ALG in your router's settings. Most VOIP providers will tell you to do this as part of setup. If yours doesn't mention it, ask.

What Switching to a New VOIP Provider Actually Looks Like

The process of switching to a VOIP provider is more straightforward than most businesses expect. Here is a realistic sequence for a 1-10 seat business starting from scratch or moving from an ISP ATA setup.Step 1: Shortlist 2-3 providers. Use this guide to identify 2-3 options that fit your size, budget, and support requirements. Contact each one -- not just to get a quote, but to assess how they handle the conversation. A good provider asks about your business before pitching a plan. A bad one leads with price.Step 2: Confirm your NBN connection type and upload speed. Most VOIP calls require 100Kbps upload per concurrent call. Check your current upload speed at speedtest.net or fast.com during business hours. Confirm your NBN connection technology (FTTP, HFC, FTTN) with your ISP -- this affects what quality you can expect and what router settings may need to change.Step 3: Decide on handsets or softphones. Will your team use physical desk phones, a softphone app on their computer, a mobile app, or a mix? Decide this before selecting a plan, as it affects which features you need and whether you are buying hardware. For physical phones, see our SIP desk phone guide for AU-available options.Step 4: Submit your number port request. If keeping your existing number, submit the port request to your new provider early -- before your old service contract ends. Provide the exact account details from your current provider (account number, service address, authorised contact). Discrepancies between your porting details and your current provider's records are the most common cause of porting delays.Step 5: Set up your call routing before go-live. Configure your auto-attendant, ring groups, after-hours voicemail, and any other call routing before the number port completes. Test with internal calls first, then with calls from a mobile. Do not go live until you have heard the call routing working correctly end-to-end.Step 6: Go live on the ported number. Once the port is confirmed, test an inbound call from an external number. Check that 000 emergency calling is working and registered to your correct service address. Confirm voicemail-to-email is delivering. Disable SIP ALG on your router if you haven't already.Most businesses complete this process in 1-2 weeks. A specialist VOIP provider should guide you through each step. If you are doing this alone without provider support, our NBN VOIP setup guide covers the technical steps in detail.

Specialist Provider vs MSP: Which Do You Actually Need?

You will sometimes hear that you should go through a Managed Service Provider (MSP) for your phone system rather than directly to a VOIP provider. MSPs have a legitimate role -- but it is not the 1-10 seat business doing basic inbound and outbound calls.An MSP makes sense when your phone system is one part of a larger IT infrastructure project: multi-site rollout, complex Active Directory integration, custom SIP trunk configuration across multiple locations, or a team that genuinely cannot manage any IT internally. In those cases, an MSP's ability to manage the whole stack has real value.For the 1-10 seat business that wants to take calls more professionally, a specialist VOIP provider like Maxotel handles the entire process end-to-end -- provisioning, porting, handset configuration, call routing setup -- without an MSP in the middle. Adding an MSP layer adds cost and a second point of contact for support. For most SMBs, it is not necessary.If you are unsure, ask the MSP or provider directly: 'What specifically would an MSP handle that you wouldn't?' A good specialist VOIP provider should be able to answer that honestly. If the answer is 'nothing in your case', go direct.

Your Next Steps Before Choosing a VOIP Provider

Before you contact any provider, work through this checklist. It takes about 15 minutes and will make every provider conversation significantly more productive.1. Count your seats. How many people in your business need to make or receive calls? Include reception, back office staff who occasionally take calls, and remote workers. This is your seat count.2. Count your concurrent call paths. At your busiest time, how many calls could realistically be happening simultaneously? A 5-person business where only 2 people are ever on the phone at once does not need 5 lines. This number drives plan sizing.3. Note your current phone number(s). Write down every business number you want to keep. Confirm which provider currently holds each number -- you will need this for port requests.4. Check your upload speed. Run a speed test from your business internet connection during business hours. Note the upload speed. Anything below 5Mbps upload needs a conversation with your provider about call quality.5. List your must-have features. Ring groups? After-hours voicemail? 1300 number? Call recording? Voicemail-to-email? CRM integration? Rank them as essential, nice-to-have, and not needed. This prevents upselling into features you will not use.6. Set your budget. Know your maximum monthly spend before any conversation. Include handsets if you need to buy new ones (budget $80-$250 AUD per desk phone).With that information in hand, use our Get a Recommendation form to tell us what you need. The Need to Know Comms Team will point you to the most suitable provider for your specific situation -- no sales pitch, no provider relationship that biases the recommendation.

What is the difference between a VOIP provider and a phone system?

A VOIP provider is the company that supplies your phone service -- your numbers, your call routing, your cloud PBX. A phone system (or PBX) is the software that manages how calls are handled: ring groups, auto-attendant, hold music, voicemail. Most hosted VOIP providers supply both as a bundled service. When someone says 'VOIP provider', they typically mean the company you pay monthly for your hosted phone service. When someone says 'phone system', they mean the call management platform, which is usually included with your provider. See our guide to business phone systems in Australia for a fuller explanation.

Can I keep my existing business phone number if I switch VOIP providers?

Yes, in almost all cases. Number porting is a regulated process in Australia under ACMA's Local Number Portability rules. Geographic numbers (02, 03, 07, 08), mobile numbers, and 1300/1800 numbers can all be ported to a new VOIP provider. The process takes 5-10 business days for most SMB ports. You need to provide your current provider's account details, service address, and authorised contact name accurately -- discrepancies are the most common cause of porting delays. Never cancel your old service before the port is confirmed complete.

How much does VOIP cost per month for a small business in Australia?

For a 3-5 seat business, expect to pay $75-$150 AUD per month for a hosted VOIP plan including your cloud PBX, numbers, ring groups, and voicemail. For 10-15 seats with a 1300 number and call recording, typical spend is $350-$600 per month. Handsets are a separate one-off cost (roughly $80-$250 AUD per phone). International providers like 8x8 and RingCentral publish pricing in USD -- convert to AUD and add GST when comparing against AU-based providers.

Is Maxotel a good VOIP provider for small business?

Maxotel is a strong option for Australian SMBs, particularly for the 1-15 seat market where consultative setup support matters. Their AU-based team, month-to-month contracts, and SMB-specialist positioning make them well-suited to businesses setting up a proper phone system for the first time. Where they are less competitive is enterprise analytics, large-scale CRM integrations, and 30+ seat deployments, where international platforms like 8x8 or RingCentral have more mature tooling. For most small businesses, Maxotel is worth including in any shortlist.

What VOIP provider works best on Australian NBN?

AU-based providers with local SIP infrastructure -- Maxotel, and providers using AU data centres -- generally deliver the best call quality on NBN connections because calls are not routing internationally. For businesses on FTTP or HFC with strong upload speeds (10Mbps+), the infrastructure location matters less. For businesses on FTTN with marginal upload speeds, local infrastructure is a meaningful advantage. In all cases, disable SIP ALG on your router and use QoS settings to prioritise VOIP traffic. See our VOIP call quality guide for the full technical checklist.

Do I need an IT person to set up a VOIP provider?

Not necessarily. Specialist AU VOIP providers like Maxotel handle setup end-to-end, including handset configuration, number porting, and call routing -- you do not need in-house IT. Larger international platforms like 8x8 or RingCentral have self-service admin portals that are manageable for a tech-comfortable business owner but can be daunting without IT support. If you want full setup support without IT, choose a provider that explicitly offers managed onboarding as part of their service. Ask the question before you sign: 'Who configures our call routing, and is that included in the plan?'

What happens to my VOIP if the power goes out?

If your NBN connection and router lose power, your VOIP service goes offline. Unlike traditional copper phone lines that drew power from the telephone network, NBN-based VOIP requires your router and NBN equipment to be powered. Solutions include a UPS (Uninterruptible Power Supply) battery backup for your router and NBN box, which buys several hours of runtime, or configuring a mobile number as a failover destination in your auto-attendant so calls divert automatically if your VOIP service goes unreachable. This is especially important for businesses in disaster-prone areas or where continuous availability is critical.

What is the difference between a VOIP provider and an ISP phone service?

An ISP phone service typically means your internet provider has put your phone number on the ATA (Analog Telephone Adapter) port built into your modem. This gives you a single phone line with no call management features -- no ring groups, no hold, no after-hours routing, no ability to run a proper business phone system. A business VOIP provider supplies a real hosted PBX service with full call management, multiple lines, and proper business features. If you are currently using the green phone port on your NBN modem, you are on an ISP ATA service, not a business VOIP service. The cost to upgrade is lower than most people expect.
