The Three Cost Categories You Need to Understand
Every VOIP cost falls into one of three buckets. Understanding these separately stops providers from obscuring the true total.First, recurring monthly costs: your plan fee per user, call charges (per-minute or included), and any add-on fees for features like call recording, additional numbers, or 1300 services. This is your ongoing operational cost and the one providers advertise most prominently.Second, one-time setup costs: number porting fees, provisioning charges, configuration time, and any initial hardware. These are often invisible in the advertised price but can easily add $500 to $2,000 to your first invoice.Third, hardware costs: the IP desk phones, headsets, or conference devices your team will use. Hardware is a one-time capital expense but needs to be factored into year-one budgeting. A team of five with decent desk phones is looking at $500 to $2,000 in hardware alone before a single call is made.Monthly phone system plan Costs: What AU Providers Are Charging
Australian cloud phone system plans sit in three clear tiers. The ranges below reflect current market pricing from providers including Maxotel, 8x8, RingCentral, net2phone, and Vonage. Always check current pricing directly with providers before committing.| Basic / Entry | Standard / Business | Premium / Advanced | |
|---|---|---|---|
| Typical Cost (AUD) | ~$15 to $25 per user/month | ~$25 to $40 per user/month | ~$40 to $60+ per user/month |
| What Is Usually Included | 1 DID number, voicemail, basic call routing, softphone app | Everything in Basic plus call recording, ring groups, IVR, auto-attendant, voicemail-to-email | Everything in Standard plus CRM integration, analytics dashboards, priority support, unlimited local/national calls |
| What Is Usually Extra | Call recording, additional numbers, 1300/1800, advanced IVR, CRM integration | CRM integration, dedicated account manager, international calling, some provider-specific add-ons | Advanced contact centre features, custom API integrations, dedicated infrastructure |
How Call Charges Work in Australia
AU VOIP call pricing has three categories: local/national calls (geographic 02/03/07/08 numbers), mobile calls (04xx numbers), and international calls. The distinction matters because mobile call rates are significantly higher than landline rates, and many 'unlimited' plans only mean unlimited landline calls.Typical AU VOIP call rates to watch for (these are add-on or per-minute rates where calls are not included in the plan):| Typical Rate (AUD) | Notes | |
|---|---|---|
| Local / national landline | ~$0.04 to $0.09 per minute | Often included in Standard and Premium plans |
| Australian mobile (04xx) | ~$0.10 to $0.22 per minute | Inclusion varies by provider and tier; check fair-use terms and excluded destinations. |
| 1300 number (outbound to) | ~$0.12 to $0.25 per call or per minute | Varies significantly by provider |
| International (NZ, US, UK) | ~$0.03 to $0.12 per minute | Depends on destination and plan tier |
| International (other) | ~$0.10 to $1.00+ per minute | Africa, Middle East, Pacific Islands vary widely |
One-Time Setup and Porting Costs
Setup costs are where new VOIP customers are most frequently surprised. These are the fees that do not appear in the advertised monthly price.| Typical Range (AUD) | Notes | |
|---|---|---|
| Number porting (per number) | ~$0 to $50 per number | Some providers include standard porting; complex ports (DDI ranges, 1300 numbers) cost more |
| 1300/1800 number porting | ~$30 to $150 per number | More complex than geographic number ports; commonly several business days to two weeks |
| System provisioning / configuration | ~$0 to $500 | Self-serve providers may include this; managed setup varies widely |
| IVR / auto-attendant setup | ~$0 to $300 | DIY via portal is free on most providers; professional setup is charged |
| DID number acquisition | ~$2 to $10 per number/month | Ongoing cost, not one-time, but often included in plan for first number |
| Contract exit fee (existing provider) | ~$0 to $500+ | Check your current contract before switching, some lock-in contracts carry exit fees |
Hardware Costs: Phones, Headsets, and Conference Devices
The reverse framework applies here: choose your service provider and plan first, confirm hardware compatibility, then purchase handsets. Buying hardware before you have a provider is one of the most common and costly mistakes in the VOIP setup process. See our guide to the best VOIP phone systems for small business for a full rundown on what to look for.| Typical Cost (AUD) | Notes | |
|---|---|---|
| IP desk phone (entry) | ~$100 to $180 | Yealink T31P, Grandstream GXP1610, basic 2-line, suitable for most SMBs |
| IP desk phone (mid-range) | ~$180 to $300 | Yealink T54W, Grandstream GXP2170, colour screen, more line keys, better audio |
| IP desk phone (premium) | ~$300 to $450 | Yealink T58W is a touchscreen model with video capability; Poly's Edge E550 is a 12-line-key phone with a 5-inch colour display and no camera. Poly's older VVX range is being wound down, so price the Edge E series for a new deployment. |
| DECT cordless VOIP handset | ~$150 to $350 | Suitable for retail floors, warehouses, mobile staff within a site |
| USB/wired headset (softphone) | ~$50 to $150 | For staff using softphone apps on a PC or laptop |
| Wireless headset (DECT/BT) | ~$120 to $300 | Plantronics Voyager, Jabra Evolve range |
| Conference phone | ~$300 to $800 | Yealink CP925, Poly Trio C60; check current supported conference-phone models and their documented pickup range. |
| ATA (Analog Telephone Adapter) | ~$60 to $150 | For connecting legacy analog handsets to a VOIP service, not recommended for new setups |

Hidden Costs Providers Do Not Advertise
These are the costs that cause surprise invoices. Read your service agreement carefully before signing.| Typical Amount (AUD) | How to Avoid It | |
|---|---|---|
| Caller ID (CID) fees | ~$2 to $5 per number/month | Ask specifically whether outbound caller ID is included or charged per number |
| Emergency 000 service fee (ESSL) | ~$1 to $3 per service/month | Applicable providers must support free access to emergency calls and maintain required customer-location records; any separate provider fee must be verified in that provider's pricing terms. |
| Regulatory compliance levy | ~$1 to $4 per service/month | Any provider-specific regulatory surcharge should be identified in the provider's published pricing or quote; ACMA does not mandate a fixed per-service retail levy. |
| Minimum monthly spend | ~$10 to $30 per account | Some providers have an account-level minimum regardless of how many users you have |
| Overage on call bundles | Varies | If you exceed included call minutes, overage rates apply, always check the overage rate, not just the included bundle |
| International call surcharges | Varies significantly | Some 'included' international calls exclude high-cost destinations, read the destination list |
| Contract exit / early termination | ~$100 to $500+ per contract | Avoid lock-in contracts where possible; month-to-month plans exist at most price tiers |
| Hardware return fees | ~$20 to $80 per device | If hardware is provider-supplied and you exit the contract, return or retain fees may apply |
Cost Comparison: ISP Bundled VOIP vs Entry business phone company vs Full cloud phone system
The most important cost comparison for Australian SMBs is not between business phone companies, it is between the ISP bundled service most businesses already have and a proper VOIP setup.| ISP bundled VOIP (green phone port) | Entry cloud phone system (e.g. Maxo Everyday PAYG) | Standard cloud phone system (e.g. Maxo Outright / BYO) | Full cloud phone system (e.g. 8x8, RingCentral) | |
|---|---|---|---|---|
| Monthly Cost (5 users, AUD) | ~$0 to $20 extra on NBN plan | ~$75 to $125/month total (5 users at $15-25) | ~$125 to $200/month total (5 users at $25-40) | ~$200 to $350/month total (5 users at $40-70) |
| Capabilities | Typically a single basic phone service with fewer PBX features; capabilities such as call waiting, hold, forwarding and voicemail vary by ISP. | Multiple lines, voicemail, softphone app, basic routing, DID number | Full IVR, call recording, ring groups, voicemail-to-email, auto-attendant, multiple numbers | Enterprise features, CRM integration, analytics, dedicated support, SLA |
| Hidden Cost Reality | Lost leads when second caller gets engaged tone. One missed lead per month likely exceeds the VOIP upgrade cost. | Setup/porting ~$50 to $200 one-time. Hardware if upgrading from analog phones. | Similar setup costs. Hardware. No significant hidden costs if plan is from a transparent provider. | Typically month-to-month but premium tiers may push toward annual contracts. Add-on feature creep. |
Total Cost of Ownership: 5-Person Team, Year 1 vs Ongoing
Real budgeting means looking at year-one cost (which includes setup and hardware) alongside ongoing cost (which is just the monthly service). The year-one figure is often double the ongoing cost, which catches businesses off guard.| Entry Tier (5 users) | Standard Tier (5 users) | Notes | |
|---|---|---|---|
| Monthly plan fee | ~$100/month (5 x $20) | ~$165/month (5 x $33) | Check current pricing with provider |
| Number porting (3 numbers) | ~$0 to $150 one-time | ~$0 to $150 one-time | Many providers include standard geographic porting |
| System setup / config | ~$0 to $200 one-time | ~$0 to $300 one-time | Self-serve portals are typically free |
| Desk phones (5 x entry Yealink) | ~$750 one-time (5 x $150) | ~$1,100 one-time (5 x $220) | Pre-configured option costs slightly more |
| Year 1 total cost (approx) | ~$1,950 to $2,300 | ~$3,080 to $3,530 | Hardware and setup are year-1 only |
| Year 2+ ongoing cost (approx) | ~$1,200/year ($100/month) | ~$1,980/year ($165/month) | No hardware refresh assumed; No hardware refresh assumed; handset service life and support lifecycle vary by model, usage and provider compatibility. |
When Cheap Equals Expensive: The Undersizing Trap
The cheapest plan in the short term is often the most expensive choice over 12 months. Here is how it plays out in practice.Scenario: a retail business chooses the entry plan at $15/user/month to save money. After three months, they discover they need call recording (for dispute resolution), a proper auto-attendant (staff are manually answering and routing calls), and voicemail-to-email (missed calls are being lost). Each of these is an add-on at $5 to $15 per month. The effective cost is now $35 to $50/user/month, which is higher than the Standard plan they dismissed. They also have the complexity of bolt-on features instead of a clean integrated setup.The correct approach: list the features you actually need before comparing plans. Match the feature list to tiers. If Standard includes everything you need, Standard is the cheapest option, not Entry.Similarly, a business that significantly undersizes its number of simultaneous call paths will experience call failures at busy periods. A five-person practice with only two simultaneous call paths may queue, divert or reject additional calls when demand exceeds that capacity, depending on its configuration. The cost of re-buying lines or upgrading to the correct tier mid-contract is often more disruptive than just sizing correctly at the start.

Australian businesses face a few cost factors that do not apply in other markets. These are worth understanding before you compare pricing from international sources.NBN Connection Type Affects Call Quality, Not Just Cost
Australia's NBN network has several access technologies: FTTP (fibre to the premises), FTTN (fibre to the node), HFC (hybrid fibre coaxial), and FW (fixed wireless). Call quality depends on end-to-end performance, including NBN technology and configuration, congestion, the ISP's network design, available bandwidth and local equipment. Your business phone company is not responsible for NBN congestion, so A higher speed tier may help if available bandwidth is the constraint; diagnose latency, jitter, packet loss, local networking and provider routing before changing either service.VOIP bandwidth requirements are modest: Bandwidth and quality thresholds vary by codec and platform; use the provider's requirements and measured latency, jitter and packet loss for the expected concurrent-call load. The number of calls a connection can support depends on measured upload performance, concurrent non-voice traffic, codec and provider requirements. The VOIP Bandwidth Calculator at needtoknowcomms.com.au/tools/voip-bandwidth-calculator/ can help you confirm your connection is adequate before committing to a service. For more detail, see our article on NBN and VOIP compatibility in Australia.The PSTN Shutdown and What It Means for Your Costs
Legacy fixed-line services have been migrated or disconnected progressively as part of the NBN rollout, but Australia did not complete a universal PSTN switch-off in 2025. Many businesses now use IP-based voice, but some legacy or non-NBN voice services remain and digital infrastructure does not automatically mean the customer has a VoIP service. The question is whether you are on an ISP-controlled ATA with no visibility or control, or a proper cloud phone system service where you own the service relationship.The practical cost implication: if you are still on an ISP ATA, you are paying for a VOIP service already (it is bundled into your NBN plan) but receiving far fewer features. Moving to a dedicated business phone company is not an additional cost on top of your current setup, it is a substitution. The incremental cost varies with provider, users, call paths, included calls, numbers and hardware; compare an itemised quote with the voice charges already included in your internet service.1300 and 1800 Number Costs in the Australian Market
Australian businesses frequently ask about 1300 and 1800 numbers when budgeting for VOIP. The key cost to understand: you pay for inbound calls to your 1300 or 1800 number, not just outbound calls. The charge structure is typically a per-call flagfall plus a per-minute rate. Monthly costs for a business receiving moderate 1300 call volume (say 200 calls per month at 3 minutes average) might be $40 to $120/month in call charges on top of the monthly number rental (~$20 to $40/month). For a full breakdown, see our dedicated guide on 1300 numbers in Australia.000 Emergency Calling Requirements and Cost
Providers supplying an emergency telephone service must comply with applicable emergency-call rules, and 000 calls must be free to end users. ACMA does not mandate a $1 to $3 monthly customer levy per service. Any provider that cannot confirm 000 support for your registered business address should be disqualified immediately.Power Outage Considerations
NBN VOIP services go offline when the power goes out, because the NBN modem/router needs power to operate. This is a cost and reliability consideration that analog landlines (which ran on their own phone line current) did not have. Mitigation options: a UPS (uninterruptible power supply) for the modem and router (~$150 to $400), or forwarding inbound calls to a mobile number and using a mobile app or cellular service for outbound calls during an outage, where supported. Most cloud phone system companies include mobile failover as a plan feature or add-on.Australian Provider Pricing Landscape
Australia has a healthy market of cloud phone system companies serving SMBs. The major players and their positioning as of early 2026:Maxotel is an Australian-owned specialist business phone company with SMB-focused plans and local support. Known for consultative onboarding and transparent pricing. Current public pricing starts at $9.95 AUD per user per month for Everyday PAYG, while the included-calls Outright/BYO plan is $29.95 per user per month. Check current pricing at maxo.com.au.8x8 is a US-based enterprise business phone company with an Australian presence. Strong on unified communications, analytics, and large-team deployments. 8x8's current Australian pricing should be confirmed through an AUD quote because its public AU pages do not establish this range reliably. More appropriate for 20+ seat deployments. Check current pricing at 8x8.com/au.RingCentral is another US-based provider with a significant AU customer base. Similar positioning to 8x8. RingCentral's current Australian RingEX pricing is quote-based; request a current AUD per-user quote and confirm the contract term. Strong on integrations (Salesforce, Microsoft 365, Google Workspace). Check current pricing at ringcentral.com.au.net2phone Australia offers SMB-focused cloud phone system with competitive pricing on Standard and Premium tiers. Confirm net2phone's current Australian availability, AUD pricing, contract term and support location directly before including it in this comparison. Check current pricing at net2phone.com.au.Vonage (now part of Ericsson) serves larger AU businesses and contact centre deployments. Pricing is typically at the higher end of the market and better suited to 20+ seat teams with integration-heavy requirements.For SMBs comparing AU providers on features rather than just price, see our full guide to the best VOIP phone systems for small business in Australia. For a deeper look at the hosted versus on-premise decision, see our guide to cloud phone system versus on-premise PBX in Australia.What Most Businesses Get Wrong About VOIP Pricing
After working through AU business communications, the same pricing mistakes appear consistently. Here are the three that cost businesses the most money.Mistake 1: Comparing Monthly Plan Fees Without Factoring in Call Charges
A plan advertised at $15/user/month sounds cheaper than one at $28/user/month. But if the $15 plan charges $0.18/minute to Australian mobiles and your team makes two hours of mobile calls per day across five users, you are adding ~$540/month in call charges. The $28 plan that includes unlimited mobile calls costs $140/month for five users, a saving of $400/month. The advertised price is almost meaningless without understanding what is included versus charged extra.Mistake 2: Ignoring Year-One Costs and Only Comparing Monthly Fees
Business owners comparing business phone companies typically look at the monthly fee and ignore setup, porting, and hardware costs. These one-time costs can easily add $1,000 to $3,000 to your first-year total. Get an all-in year-one quote from any provider before committing, not just the monthly plan fee. A good provider will give you this without being asked.Mistake 3: Treating the ISP ATA Service as 'Free'
Many Australian SMBs are running their business on the free phone service bundled with their NBN plan, treating it as a $0 cost because it appears on the same bill as their internet. This is a false economy. Basic ISP voice services usually provide fewer PBX features, but second-call handling depends on whether call waiting, forwarding or voicemail is enabled. At $50 to $150 per month for a proper cloud phone system service, the cost is recovered by retaining a single additional customer call per month for most businesses. The ISP ATA is not free, it charges you in lost leads.Your Next Steps: How to Budget for VOIP Accurately
Before you request a quote from any business phone company, work through this checklist. You will get better quotes and avoid the common surprises.Step 1: Count your users and concurrent call paths. How many staff need a phone? How many simultaneous calls do you expect at peak? (Hint: peak simultaneous-call demand varies by business; use call records or measured peak traffic rather than a fixed percentage of headcount.)Step 2: List the features you actually need. Ring groups? Call recording? Auto-attendant? Voicemail-to-email? CRM integration? Do not pay for features you will not use, but do not undersize either.Step 3: Estimate your call volume. How many calls per day? What mix of landline, mobile, and international? This tells you whether unlimited call plans save you money or cost you more.Step 4: Get an itemised quote from at least two AU providers that includes setup, porting, and hardware, not just the monthly fee. Compare year-one total cost, not just the monthly plan price.Step 5: Ask every provider: what is included in the plan, what is an add-on, and what are the overage rates? Get the answers in writing before you sign.Step 6: Check your NBN connection type and speed. Confirm your upload speed and jitter are adequate for your expected simultaneous call load. Use the VOIP cost calculator to model your expected monthly costs before talking to any provider.Once you have worked through these steps, you are ready to get a recommendation.
